Hello,

Last weekend I noticed 1/4 of the speedometer of my car had no light. I don't know how much time it has been like this but I don't think it can be much...

There are two things I've done that could have produced some kind of electrical malfunction: I changed the plate lights to LEDs and my wife plugged her phone to the lighter plug during some hours. I removed the LED plate lights for the old ones and I've replaced the fuse number 12 which is the one assigned to the cluster and the lighter plugs... but nothing changed.

It's weird cause during the weekend, I guess it changed from no light at all to a little bit... I don't know if it's just the light of the rest of the speedometer being transmitted to that segment, but it looks that it has recovered (by itself) a little bit.

Looking for solutions I've found there's a procedure to reset the cluster to check if every led works, but my cluster doesn't have a "reset trip" / odometer button... Is there another procedure for this diagnostic?

Or any other fuse I could try to replace?

Any idea or help will be greatly appreciated.

Thank you in advance!!

I've made the cluster test work by pressing down one of the arrow buttons (I think it's the up one ) . It tested all the light intensities and moved all the gauges but in the end the illumination intensity of the failing segment never recovered the usual look... The right-down part still has a very weak illumination...

I also tried changing other fuses related to the cluster and interior illumination without any success...

Any idea??

Sorry to hear about the Instrument Cluster (IC) issue your having. It sounds like your issue may be related to a faulty LED unit.

The IC has several serviced components. The gauges, indicators, electronic display unit, electronic circuit board and housing are only serviced as an assembly and cannot be adjusted or repaired. If a gauge, an LED unit, the electronic display unit, the electronic circuit board, the circuit board hardware, the cluster overlay or the cluster housing is damaged or ineffective, the entire IC unit must be replaced. The cluster lens, hood and mask are available for separate service replacement.

The instrument cluster (IC) (also known as the Instrument Panel Cluster/IPC) for this vehicle is located directly in front of the driver, above the steering column opening. The mounts and the electrical connections, are concealed within the instrument panel behind various trim panels and the cluster itself. The IC contains various indicators, analog gauges, an electronic display unit and an integrated circuit board. The electronic display unit displays odometer information and several indicators, some of which are model dependant.

The optional Electronic Vehicle Information Center (EVIC) makes use of the IC electronic display unit. The EVIC feature provides display options of the outside ambient temperature, compass headings, average fuel economy, elapsed time, numerous textual warning messages, reminder indicators and certain diagnostic information.

The IC includes an electronic display unit. The electronic display unit is soldered to the electronic circuit board, and is visible through a window with a smoked lens between the tachometer on the left and speedometer on the right. The dark lens prevents it from being clearly visible when it is not illuminated.

The odometer information is displayed within the electronic display unit. The odometer information is stored in the IC memory. This information can be increased when the proper inputs are provided, but the information cannot be decreased. The odometer can display values up to 999,999 kilometers (999,999 miles). The odometer latches at these values, and will not roll over to zero.

The odometer display does not show leading zeroes, does not have a decimal point and will not show values less than a full unit (kilometer or mile). The unit of measure (km or miles) for the odometer display is shown in the electronic display in the same color and at the same lighting level as the odometer values. The unit of measure for the odometer can be selected using the customer programmable features function of the Integrated Center Stack (ICS) screen module. The odometer has a RENTAL CAR mode, which will illuminate the odometer information in the display whenever either front door is opened while the ignition switch status is OFF or ACCESSORY.

During daylight hours (exterior lamps are OFF) the electronic display unit is illuminated at full brightness for clear visibility. At night (exterior lamps are ON), the electronic display unit lighting level is adjusted with the other cluster general illumination lamps using the panel lamps dimmer function of the interior lighting dimmer control. However, a PARADE mode position of the dimmer control allows the display to be illuminated at full brightness if the exterior lamps are turned ON during daylight hours.

Dual trip odometer (Trip A and Trip B) capability is standard equipment on this vehicle. Both trip odometers appear within the electronic display unit. The trip odometer information is also stored in the IC memory. Each trip odometer can display values up to 16099.9 kilometers (9999.9 miles). Each trip odometer will roll over to zero independently when it accumulates these values. The trip odometer minimum value is 0.0 (miles or kilometers) and does have a decimal point to show values of tenths of a full unit (miles or kilometers).

The unit of measure (km or miles) for the trip odometer display is shown next to the Trip A or Trip B text in the display in the same color and at the same lighting level as the trip odometer values. The unit of measure for the trip odometer can also be selected using the customer programmable features function of the ICS screen module.
