That means the 4wd switch on your dash is faulty and needs to be replaced.

SOURCE: all gauges on instument cluster not working

In most vehicles there is a wiring harness that runs under your dash to your heater etc. Sometimes the main plug comes loose. If you open up the steering column or somewhere down by your feet on the steering column is the main plug - look in your manual and track the wires with a tester ensuring you have power all the way to whatever is not working. If there is no power at the main plug then you might have a ground problem or a loose wire in the plug itself. Good luck

SOURCE: 95 saab 900 turb0 gauge cluster works intermetanly

I have this problem too and my new Saab mechanic told me that I would probably need a new instrument cluster. He said a brand new one costs $2500 but that he would order me a used one from a car that had fewer miles than mine as you can set them back but not forward. He both diagnosed and temporarily "fixed" the problem by slamming his hand really hard on the dash over the panel and all the lights and gauges immediately started working fine....for now. I haven't had the work done yet (I have a 1998 Saab 900S with 130K) so if anyone has any other ideas about this I would love to know what they are. This issue with the gauges and dash lights has been happening on and off for over a YEAR and this is the first time someone has had any idea what it is. I already had my ignition switched replaced so we know that's not what it was. THANKS

2007 mercury mountaineer wrench light lit. what is that mean?


Wrench Warning Indicator (Base Instrument Cluster)
The instrument cluster receives the powertrain status from the PCM over the HS-CAN. When a powertrain system concern is detected, the PCM sends the instrument cluster a command signal to illuminate the wrench warning indicator. If the 4WD control module detects a failure with the 4WD drive system, the 4WD control module sends a message to the instrument cluster over the CAN to illuminate the wrench warning indicator. On 4.6L engines, if the transmission control module (TCM) detects a failure with the transmission, the TCM sends a message to the instrument cluster over the CAN to illuminate the wrench warning indicator.

It means a trip to the dealer or some other qualified repair shop .

Service 4wd bad accelerator


Hi there:
The FDCM has a code, and for me to be able to correctly diagnose your vehicle..You will need to get that code retrieved by a scantool.\.

The service 4WD indicator gives an indication to the vehicle operator when the Final Drive Control Module (FDCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer case circuit or component malfunction. This indicator is controlled by the instrument cluster logic circuit based upon cluster programming and electronic messages received by the cluster from the FDCM over the Controller Area Network (CAN) data bus.

The service 4WD indicator function of the reconfigurable dot matrix Organic Light Emitting Diode (OLED) display unit is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the OLED service 4WD indication will always be OFF when the ignition switch is in any position except ON or START. The instrument cluster will turn ON the service 4WD indicator for the following reasons:

Service 4WD Indicator Lamp-On Message - Each time the cluster receives an electronic service 4WD indicator lamp-ON message from the FDCM, the service 4WD indicator will be illuminated. The indicator remains illuminated for about five seconds, until the cluster receives a lamp-OFF message from the FDCM, until the cluster arbitrator logic determines that another display request has priority, or until the ignition switch is turned to the OFF position, whichever occurs first.

The FDCM continually monitors the electronic transfer case control circuits and transfer case shift motor/mode sensor assembly to determine the condition of the system. The FDCM then sends the proper lamp-ON or lamp-OFF message to the instrument cluster, also known as the Cab Compartment Node (CCN).

For proper diagnosis of the FDCM, the CCN, the CAN data bus or the electronic communication related to service 4WD indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.

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, have a nice day.

We have an intermittent problem with the instrument cluster. You will be driving along and the entire cluster dies. No tach, no speedometer, no lights, etc. Usually within the next 3 or 4 times the van is...


This is a bad connection within the printed circuit of the instument cluster. It seems to be worse in higher temps, like being in the sun with the windows up for several hours. (I feel it should be a recall) Sometimes a firm tap on the face of the cluster will bring it back, but the only solution at this point is to repace the cluster.

Instrument cluster is going crazy on my 2003 Isuzu Ascender, tach stays at 7000 RPM, fuel gauge all over the place, ammeter says 19 volts, check engine light on & off, among other things.


It may have a faulty cluster. Or possibly could have a charging system problem.
Take it to a dealer and have it scanned for codes.
The instument cluster is a module that can store trouble codes. If the cluster is at fault the new one will have to be programmed to the vehicle to work correctly.

Abs light/traction control light


You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.

Instument Guages


well the issue is youe enitre gauge cluster i do understand that your speedometer is working but it is a cable speedometer not electronic like everything else in the gauge cluster so first i would recomend checking the voltage getting to your gauge cluster then just replace the guagecluster they are really cheap i a salvage and not hard to install at all but the cluster itself is not very comon to go out so make sure you check voltage to it first i wouldnt want you to go through buying and replaceing the cluster and that not fix it
