VFR 800 F1 2001: The problem i have is: when road

VFR 800 F1 2001: The problem i have is: when road lights are switched on, the indicator lamps on the instrument panel glow dimly. Upon indicating the two lights flash alternately in time with the flasher unit, with the opposite lamp being brighter to the actual direction being turned. The instrument back lights are also affected to a degree. all is fine with road lighting off. Thanks

    The problem will more than likely be corrosion on the PCB on the back of the instrument cluster. It is around £180 to rpelace or you can solder wires across the broken parts, look on the VFR forums, there are many threads. This will also cause all sorts of malfunctions with the instruments.

  • Dave Troughton Jan 10, 2010

    I have since fixed the problem. it was the Printed Circuit Board (PCB)on the back of the instrument cluster. It is a common fault as the PCB has not been treated with a protector. VFR forums have covered it widely and step by step guides are available. It will cause a number of instrument faults, depending upon which circuits are affected by corrosion. The PCB is about £180 to replace, so repairing as i did is worth a go.

Had this exact same problem. It is the earth return in the connector behind the left hand fairing. it tends to corrode and overheat. Best way round it is to make a jumper cable and bridge the earth wire.

Back lighting or warning lights ? check engine , ABS , air bags , seat belt , oil light etc... ?
Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
• Power window switches
• HVAC control head assembly
• Radio
• The instrument panel cluster (IPC)
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

I would have it checked for DTC'S - diagnostic trouble codes stored in the BCM !
DTC B2624 Display Dimming Input Range/Performance
The body control module (BCM) supplies voltage to the instrument panel dimmer switch through the instrument panel dimmer switch signal circuit. The dimmer switch varies the voltage and returns the new voltage to the BCM through the dimmer switch signal return circuit. The BCM uses this voltage to determine the illumination level of the instrument panel lamps.

DTC B2625 Display Dimming Pulse Width Modulation (PWM) Output Circuit Range/Performance
The body control module (BCM) receives a variable voltage from the instrument panel (I/P) lamp dimmer switch. The BCM uses this signal in order to vary the illumination level of the I/P lamps. The I/P dimming lamps output from the BCM is a pulse width modulated voltage supply used to light the I/P lamps. If a malfunction occurs in the I/P dimming lamps output circuit, this DTC is set.

DTC B2662 Park Lamp Switch Circuit Malfunction
The park lamps are controlled by the turn/headlamp switch. Positive battery voltage is supplied to the switch through the EXT LP fuse. When the turn/headlamp switch is placed in the park or head position, battery voltage is supplied to the park lamps. The body control module (BCM) is also connected to the park lamp circuit to sense whether or not the park lamps turn ON when the low beam or high beam headlamps are turned ON. The BCM also uses the parklamp battery positive voltage to power the instrument panel (I/P) dimmer output circuit. If the BCM senses that the low beam or high beam headlamps are ON and the park lamp input is not active, DTC B2662 sets.
Do the park lamps work ?

I have a 2002 Buick Rendezvous and the radio and heater control backlights have shut off simultaneously and now only the vent control and trunk release lights work.


I would take a look see at the ground circuits for the none working lights . The incandescent back lighting lamps are then grounded at G200, G301 and G302. You would need factory service info for the location of the grounds .Like this from buick
G200
Right side of the I/P, secured on the underside of the cross car beam, behind the I/P compartment . The I/P compartment is the glove box ,don't know why they just don't say that . You could also check out the power and ground from the componet that's not working ! You can find factory like service info. from alldata

Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and of incandescent lamps.
• The door switches and the window switches
• The HVAC control head assembly
• The radio
• The instrument panel cluster (IPC)
• The steering wheel controls
• The heated seat switch
• The HUD switch
• The lift glass window release switch and traction control switch
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) displays (radio and HVAC control assembly), incandescent lamps, turn on at maximum brightness. When the park lamps are on and the ambient light sensor indicates low light conditions, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The BCM L fuse in the console fuse block, supplies battery positive voltage to the BCM. The I/P courtesy lamps supply voltage circuit of the BCM, supplies battery positive voltage to all the dimmable lamps. When the headlamp switch is placed in the PARK position, the BCM will then dim the interior lamps to the dimming level indicated by the IP dimmer switch. When the driver selects a dimming setting by moving, the IP dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. The incandescent back lighting lamps are then grounded at G200, G301 and G302. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.
The driver may select parade mode by manually turning on the park lamps during daylight conditions. The front park lamp circuit supplies voltage to the instrument panel cluster, radio and HVAC assembly for a park lamp on input, and the displays will become full bright.

2000 Buick LeSabre - trunk lights, back up lights dont work


Backup Lamp Circuit Description
Battery positive voltage (B+) is supplied at all times to the REVERSE relay coil through the rear fuse block. Battery positive voltage (B+) is supplied at all times from the rear fuse block NSBU Fuse to the REVERSE relay switch. The powertrain control module (PCM) sends a class 2 message to the rear integration module (RIM) indicating that the gear selector lever is in the REVERSE position. The dash integration module (DIM) sends a class 2 message through power moding that the ignition switch is in the ON position. When these conditions occur, the RIM grounds the REVERSE relay coil. The coil is energized, closing the switch contacts. This supplies battery positive voltage (B+) to the backup lamps. The backup lamps are both permanently grounded, so both backup lamps have power and ground, and then light.

Do you know about class 2 serial data communications between control modules ? Do you know there is a fuse box under the rear seat ?

This is information taken from a Buick service repair manual !

Park Lamps
The dash integration module (DIM) supplies battery positive voltage (B+) to the PRK LP relay coil. When the headlamps or park lamps need to be on or when the ignition switch is in the ON position. Battery positive voltage (B+) is supplied at all times to the PRK LP relay switch. When the park lamps are to be active, the DIM grounds the PRK LP relay coil. The coil is energized, closing the switch contacts. Battery positive voltage (B+) is supplied to the rear fuse block RH PARK LP Fuse, LH PARK LP Fuse, and DIMR Fuse. The LH PARK LP Fuse supplies battery positive voltage (B+) to the LH park lamps. The LH PARK LP Fuse supplies battery positive voltage (B+) to the LH park lamps. The LH and RH park lamps are permanently grounded, so all park lamps have power and ground, and then light. The DIMR Fuse supplies battery positive voltage (B+) to the DIM park lamp input for interior lamps dimming, the license lamps, the underhood lamp, and the cornering lamps. The license lamps are permanently grounded, so both license lamps have power and ground, and then light.

The body control system consists of 3 modules:
• The dash integration module (DIM)
• The instrument panel module (IPM)
• The rear integration module (RIM)
Dash Integration Module (DIM)
Battery voltage is provided from the rear fuse block to the DIM. The module ground is wired to ground. Battery positive sense voltage is provided from the rear fuse block to the DIM. This battery input is referenced to the ground sense input at DIM which is wired to the battery negative terminal and to ground. These sense inputs are physically connected to the battery positive and negative terminals for accurate battery voltage readings. The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
Instrument Panel Module (IPM)
Battery voltage is provided from the underhood fuse block to the IPM. Ignition voltage is provided from the rear fuse block to the IPM. The voltage inputs are referenced to the module ground. The IPM is wired to the class 2 serial data line. The various IPM input and output circuits are described in the corresponding functional areas as indicated on the IPM electrical schematics.
Rear Integration Module (RIM)
Battery voltage is provided from the rear fuse block to the RIM. Ignition voltage is provided from the rear fuse block to the RIM. These voltage inputs are referenced to module ground. The RIM is wired to the class 2 serial data line. The various RIM input and output circuits are described in the corresponding functional areas as indicated on the RIM electrical schematics.
Rear Integration Module (RIM)
The RIM functions include the following functions:
• Heated seat controls
• Rear defogger control
• Park relay controls
• Various controls for the interior lamps
• Reverse control for the backup lamps
• Rear compartment lid release controls
• Retained Accessory Power (RAP) control
• Ajar switch and tamper switch inputs from the rear compartment lid
• Vehicle leveling
Your best bet would be to take your vehicle to a qualified repair shop ! No offence but this is complex an a factory or professional grade scan tool is needed , could have DTC'S - diagnostic trouble codes stored .
Body Control System Description
The body control system consists of the following 3 modules:
• The dash integration module (DIM), located behind the instrument panel, under the right dash sound insulator.
• The instrument panel module (IPM), located behind the instrument panel, under the left dash sound insulator.
• The rear integration module (RIM), located behind the rear seat back cushion (upper, left).

Dashboard lights will go out randomly. It has done it for short periods before but it did it for 200 miles on hwy in dark.


The sensor is usually located on the top of your dashboard. You might see it if you look into your vehicle through your windshield at your dash.
I have seen( one time ) that a gps was bright enough that it caused the dash lights not to come on because the sensor thought it was light outside.
Or you could have gotten a bad sensor.

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

How do I fix my 99 blazer the dome lights won't turn on and the 4 who drive won't light up or work


In the instrument panel fuse box fuse # 8 CTSY LP 10A ,that's for the dome lights, fuse panel is left side of IP. What are you talking about 4 who drive won't light up or work ? 4 wheel drive ? Do you have two speed automatic or two speed selectable ?
Switch Indicator Lamps Do Not Light - One or More ? Check fuse #15 IP fuse box 10A 4WD . This is for two speed auto !

Circuit Description

The indicator lamps circuits consist of 5 individual lamps contained inside the mode/range switch assembly, they are AUTO, 4WD, 2HI, 4HI, 4LO and NEUTRAL. The AUTO, 4WD, 2HI, 4HI, and 4LO lamps are contained inside their respective range button. When the ignition is ON, the transfer case shift control module illuminates the indicator lamp that corresponds to the current ATC gear position by providing a ground through a current limiting driver.
The transfer case shift control module flashes each indicator lamp after a shift has been requested and will continue to flash until the transfer case shift control module can complete the shift. After a shift to AUTO, 4WD, 2HI, 4HI, or 4LO is made, the transfer case shift control module will flash that indicator lamp until the transfer case shift control module receives a high voltage signal on CKT 1695 from the front axle switch.
A solid state circuit located inside the switch supplies ignition voltage to the lamps. The solid state circuit also receives voltage whenever the headlamp switch is in park or headlamp position. When the solid state circuit receives voltage from the headlamp switch it will reduce the voltage that it supplies to the indicator lamps, dimming the lamps when the headlamps are ON.

Could have connection issues at the BCM - body control module , lose ground . The BCM controls all the thing's your have problems with .
Turn Signal Lamps
When the turn signal switch is place in either the right or left turn position, the turn/hazard request circuit is pulled low, through a resistor. The body control module (BCM) uses the resistors to determine if the left or right turn signals have been requested. The BCM then supplies an ON-OFF voltage to the turn signal lamps and turn signal indicator on the selected side of the vehicle. The turn signals receive a ground at G101, G401, or G403.

When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

Engine Coolant Indicator(s)
LOW COOLANT LEVEL
The IPC illuminates the low coolant warning indicator when any of the following occur:
• The BCM detects a low coolant level condition for at least 30 seconds. The IPC receives a class 2 message from the BCM requesting illumination.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds .

The thing to do first would be to hook up a factory or professional type scan tool an check for Instrument cluster or BCM DTC'S - diagnostic trouble codes . Then checking connection 's at the BCM , testing power an grounds .
