R6 2005 gauge cluster problem

More than likely a broken wire, corroded connector or a chafed wire.

1. cluster failure whole or in part, check fuses first .(all cab/bay)
2. scan the PCm if the comm network fails it can not talk to the cluster then data to the cluster fails but does the ODOMeter roll and work for miles.?
3. the tachometer RPM uses PCM tachometer data, so the comms are dead.
4. see this drawing for (RPM) is best as engine runs but gauge not.

the clusted must get data from the PCM or fails
and the 2 fuses good.right one called METER,. 7.5AMP
TO FIX ANY MODERN CAR TAKES A SCAN TOOL

You might have to replace the speedometer cable

Check engine light ,abs , air bag lights etc.... come on when key turned on ?
Fuse IPC/HVAC BATT 10 amp located in the left IP junction block . Do you know where this junction box is ?
Does the heater an A/C work ? If so the fuse isn't the problem .
Speedometer
The speedometer is a road indicator. The vehicle speed sensor (VSS) is a permanent magnet generator which is located on the transaxle. The VSS sends an input to the PCM whenever the transaxle differential carrier turns. The PCM then buffers the VSS signal. The PCM transmits the VSS signal to the following components at 4000 pulses/mile through CKT 817:
• The instrument cluster
• The cruise control module
• The radio (uplevel)
The instrument cluster uses the input in order to indicate the vehicle speed on the speedometer.
Instrument Cluster Indicators
The BCM controls the instrument cluster indicators through the SPI serial data communication bus. Refer to Body Control Module System Check in Body Control System.

The speed sensor on your trans sends a signal to the electronics telling it when to shift, this will be where you fault is.

instrument cluster is bad

The connector on the back of the gauge cluster isn't making a good connection. If the speed senser is bad the speedometer won't work either or the fuse the speedometer won't work but if the speedometer does work the trans controller or the shift switch ( park neuurtal drive ) could bemaking abad connection or be full of tans fluild or water (frozen?) The tach not working may indicate a fuse or connection problem to the cluster ( speedometer gauge unit and the computer doesn't know how fast the motor is going) The check engine light should be on in this case and checking for codes and following the repair recomedations for them should find the problem

these dashboards are a a pain! there are fuses in the fusebo under the bonnet, check them firt, also remove them and put them back to see if it resets it, if not then there is a test you can do,,,,,

press the mileage button on the dash, turn the ignition key to position one release the button and the das should perform a complete check, i.e gauges and mileage pixel.

Good luck Davelee, p.s, please rate me.

probally need to check engine groundwires. clean all terminals. battery may have loose terminal.

check for loose connection at the instrument cluster.
