I have an 06 ford explorer the instrument cluster lights and radio lights don't work


Are these the lights you are talking about ?
Instrument Cluster and Panel Illumination The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the headlamp switch is in either the PARKING LAMPS ON or HEADLAMPS ON position. The level of intensity is adjustable by rotating the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.
Fixed Backlighting When the accessory delay relay is energized, switched voltage is supplied to the non-dimmable components and switches.
Dimmable Backlighting When the parking lamps or the headlamps are in the ON position the smart junction box (SJB) monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable components and switches based on input received from the instrument panel dimmer switch. The SJB also sends a message over the controller area network (CAN) to the audio unit, and the instrument cluster to indicate the backlighting intensity level.
If you don't know about PWM an smart junction box your better off taking your vehicle to a quailified repair shop ! You don't the diagnostic tools or technical information . May have DTC'S - diagnostic trouble codes stored in the SJB (computer ). Do you know where SJB is located ?

  • check that the program card is correctly installed.
  • check the connections to the vehicle.
  • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
  • CAN circuits fault; all electronic control units no response/not equipped, refer to Section 418-00 .
  • No response/not equipped for SJB, refer to Section 419-10 .
  • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the SJB.
  1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

What is the location of fuse for speedometer on 2o04 ford explorer


Speedometer The instrument cluster receives the vehicle speed sensor (VSS) signal from the powertrain control module (PCM) through the standard corporate protocol (SCP) communication network. The instrument cluster monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.
  • The speedometer/odometer is inoperative
  • Circuitry.
  • Powertrain control module (PCM).
  • Instrument cluster.
  • Go To Pinpoint Test L .
PINPOINT TEST L: THE SPEEDOMETER/ODOMETER IS INOPERATIVE Test Step Result / Action to Take L1 RETRIEVE THE RECORDED DTCS FROM BOTH CONTINUOUS AND ON-DEMAND INSTRUMENT CLUSTER SELF-TESTS
  • Use the recorded instrument cluster DTCs from the continuous and on-demand self-tests.
  • Are any instrument cluster DTCs recorded?
Yes
If instrument cluster U1123 is retrieved, REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

For all other instrument cluster DTCs, REFER to the Instrument Cluster Diagnostic Trouble Code (DTC) Index.

No
For inoperative speedometer, GO to L2 .

For inoperative odometer, GO to L3 . L2 CARRY OUT THE SPEEDOMETER ACTIVE COMMAND USING THE DIAGNOSTIC TOOL
  • Connect the diagnostic tool.
  • Key in ON position.
  • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
  • Select the instrument cluster speedometer active command.
  • Trigger the speedometer and scroll in increments of 10% while monitoring the speedometer. The speedometer should increase in increments of approximately 20 km/h (12 mph) for each 10% change.
  • Does the speedometer increase within specifications?
Yes
REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual to continue diagnosis.

No
GO to L4 . L3 MONITOR THE INTEGRATED CIRCUIT DISPLAYS
  • Key in ON position.
  • Monitor the compass, air temperature and message center functions of the integrated circuit display.
  • Do the compass, air temperature or message center displays operate correctly?
Yes
GO to L4 .

No
Go To Pinpoint Test AE . L4 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
  • Disconnect all instrument cluster connectors.
  • Check for:
    • corrosion
    • pushed-out pins
  • Connect all instrument cluster connectors and make sure they seat correctly.
  • Operate the system and verify the concern is still present.
  • Is the concern still present?
Yes
INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. There isn't a fuse just for the speedometer , there are four fuse for the whole instrument cluster . If one of these fuse's were burnt you would have more then just the speedometer not working ! You need to have a scan tool to find out what is up ! you could need a new cluster ! Is the check engine light on ? if not wouldn't think vehicle speed sensor bad , besides speed info for speedometer PCM uses for transmission shift points ! Good luck ,hope this helps !

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

When I put my 1998 Pontiac Transport Montana into gear the ABS and TCS warning lights come on and stay on


The only way to know where the concern is would be to retrieve the trouble codes; without scan tool, this information not provided by the manufacturer.

Self-diagnosis procedures (with the diagnostic scan tool):
- With the ignition switch OFF, connect the diagnostic scan tool (Hi-scan pro) to the data link connector located under side of master vacuum in engine compartment.
- Make sure the ignition switch is in the on position, and then choose correct vehicle and model, proceed to diagnostic data link menu item.
- Choose the inspection item after initializing the unit.
- Press malfunction code detection No. 1 and diagnostic scan tool will display any malfunction code found.
Notice: A malfunction code is a four-digit number that is continuously output until the failure code is erased by the diagnostic scan tool.
- From the list of failure codes, verify the failed part and repair it according to self-diagnosis procedures.
- After repair, erase all malfunction codes stored in the ABS control unit by selecting inspection item (No. 4).

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

ABS light comes on... but no noticble degradation in operation etc.


Most likely a wheel speed sensor, hopefully... The only thing that will change when the ABS light is on is that the ABS will not function as long as the indicator is on. I hope this info helps.

When the airbag system is in functioning condition, the airbag warning light will remain on for about 7 seconds and go out when the ignition switch is set to ON .

If there is any malfunction, the airbag warning light will either stay on or off continuously. In such cases, perform on-board diagnostic in accordance with the specified procedure to determine trouble codes.


  1. Turn ignition switch ON (with engine OFF ).
85091723



  1. Connect DIAG. terminal to No.2 terminal of diagnosis connector located inside lower cover.
  2. Check in accordance with the trouble code indicated by the AIRBAG warning light, and record the trouble codes.
  3. Turn the ignition switch "OFF " and remove the DIAG. terminal from No.2 terminal of diagnosis connector.
85091724


HOW TO READ TROUBLE CODES
The ABS lamp flashes a code corresponding to the faulty parts.

The long segment (1.2 secs on) indicates a "ten", and the short segment (0.3 secs on) indicates a "one".





NOTE: This is the only information provided by the manufacturer for clearing diagnostic trouble codes.

97511505


CLEAR MEMORY
After eliminating problem as per trouble code, clear memory as follows:

Make sure ignition switch is ON (and engine off). Connect one DIAG. terminal (1) on diagnosis connector (2) terminal No.1.

where warning light is flashing, connect the other DIAG. terminal (3) on terminal No. 2 for at least three seconds . After memory is cleared, normal warning light flashing rate resumes. (Warning light flashes every 0.6 seconds (ON-OFF operation.) Memory cannot be cleared if any problem exists.

After clear memory and then DIAG. terminals (1) and (3), extract from diagnosis connector (2)
