SOURCE: Illumination v. Dimmer

Good day,

The illum wire goes directly to the headlight switch and tells it when to light up, where as the dimmer wire is variable meaning it would dim up or down with your dash light control. Dimmmer is usually only need on factory radio's and not aftermarket. I suggest wiring only to the illuum lead and do not connect dim. Also about the clock make sure your red and yellow wires are not crossed, yellow is a constant hot and red is only hot when the ignition is on, so if they are backwards the radio would loose it's memory when you turn the key off.

Hope this helps

illumination wire does not need to be installed on this model. depending on your car, it may use odd voltage for the dash lights. Clip and tape off the illumination wire going to the harness.

havent a clue without looking at it but this is one of them things best left alone as i have had similar before where it runs through radio,including the alarm and the factory immobiliser cut in.just loop from another circuit to make the lights work

SOURCE: Dim Mode

Make sure the orange wire with white stripe is connected to your dash illumination/parking lamp circuit. There should be a tag on it that says 'ILLUM' (unless the installer clipped it). That should dim the display whenever your lights are on.

If that doesn't do it enough I think your going to have to dial down the brighness - and that will do it for all functions.

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

2011 Jeep liberty, wife said her lights on the radio are not working, said she can not see the clock light or stations , but radio still works? I don't think it's a fuse if the radio still plays.


The lights on the radio are dimmed with the instrument panel dimmer control so usually they are fed with a separate 12 volt signal that is separate from the main radio power. It may have a separate fuse but may not. If it's not a fuse it could be a loose connector going to the radio, assuming the rest of the instrument panel lights are working correctly. I suppose it is also possible that the dimmer control has two sections, one for the radio and one for the panel lights, and the section for the radio is bad. Run the dimmer control back and forth stop to stop a few times, push on it etc. to see if that effects it. I suspect it is somewhere in the dimmer circuit.

SERVICE ELECTRICAL SYS - 106
The IPC illuminates the SERVICE ELECTRICAL SYS -- 106 message in the DIC when one of the following conditions exist:
?€¢
The dash integration module (DIM) detects a malfunction that is related to the ignition switch.


The IPC receives a class 2 message requesting illumination from the DIM.


?€¢
There is a powertrain related code present.


The IPC receives a class 2 message requesting illumination from the PCM. Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
?€¢
Class 2 communication requiring DIM interaction.


?€¢
Control of exterior lamps.


?€¢
Control of front fog lights.


?€¢
Control of the headlights.


?€¢
Headlamps on with wiper input.


?€¢
Hood ajar switch input w/export.


?€¢
Horn relay control.


?€¢
Interior lamps incandescent dimming.


?€¢
Low side temperature for HVAC compressor.


?€¢
Power moding control over Class 2 serial data circuit.


?€¢
Reverse lockout solenoid control.


?€¢
Steering wheel controls input.


?€¢
Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules.


On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle the PMM is the DIM. The PMM receives 4 signals from the ignition switch.
To determine the correct power mode the PMM uses the following circuits:
?€¢
Accessory voltage


?€¢
Ignition 1 voltage


?€¢
Ignition 3 voltage


?€¢
Off/Run/Crank voltage


Your having a module problem , need to have it checked for DTC'S . Dealer only one for that !

2001 Civic dimmer not working


It's not high and low beam, it's the dash lights that are dim. I've hooked up many aftermarket radios but never knew it was a no no to hook up the dimmer/illumination orange wires in a '01 civic. I googled it and seen many others with similar issues like mine but nothing exactly like the issue I have.

All the dash lights work, they are dim though. The radio lights work but they are even more dim than the rest of the dash lights. I have check every single fuse under the dash and in the engine bay. The dim controller does not work at all now. I'm guessing that's the issue and from what I read, the dimmers circuit board is in the instrument cluster. Some can fix it, others can't.


I will probably end up buying a used instrument cluster off of ebay, they are not expensive. Hopefully that fixes it since everything else works.


Oh, yes, the brake lights work.


Ted, I think you answered the wrong question...I mentioned nothing about the battery or the low/hi beams

Dash lights go on and off while driving, then headlights do the same


Test the electrical circuit's ! Look at a wiring diagram so you know what wire's to test . Watch these video's , buy a DVOM - digital volt ohm meter . Learn to test so you don't listen to guesses .
Basic Electricity for Service Techs Ohm law Current Flow Opens Shorts
Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
Electric Testing Techniques You Need to Know Free wiring diagrams here . http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on lighting ,then under subsystem click headlamps . Click the search button then the blue link's . Right away in the first diagram i see the headlamp / panel dimmer switch is a input to the BCM - body control module . I mite think your first response would be to want to replace the BCM ! Reading a discription of how the lights are suppose to work may shed some light on the problem .
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain on until turned off or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated.

Having the vehicle checked for DTC'S - diagnostic trouble codes , BCM - codes ! Need a professional type scan tool . Part stores can't read body codes , dealer or independent repair shop .

DTC B2575
When the body control module (BCM) senses a request for low beam headlamp illumination, the BCM sends a ground signal to the low beam headlamp relay through the headlamp low beam relay control circuit. The headlamp low beam relay will apply voltage to illuminate the headlamps.
DTC B2580
When the body control module (BCM) receives a ground signal from the multifunction high beam or flash to pass (FTP) switch commanding to illuminate the high beam headlamps, the BCM will energize the high beam relay by grounding the high beam relay control circuit.
DTC B2600
DTC B2610
The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuit.
Voltage for the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 2 A fuse in the instrument panel fuse block directly through the BCM to these circuits.

DTC B2620
The BCM directly sends a 5 volt reference voltage to the I/P dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a dimming return and dimming input to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.

Your best bet , take it to a qualified repair shop .

2005 bUICK park avenue ultra, the climate control indicator goes dim, I hit the dash and the light comes on stronger


There are 3 things to think what can be the problem.
1. there is a day/night sensor on the dash.{not working properly}
2. there is a variable dimmer for the cluster illumination. loose connector or terminals.
3. The display itself.{can be defect} loose connection at the display or terminals.
lot of work.

Hope it helps.
