Main Guage Panel Diagnostic
 
Awhile back, msantos posted the following instructions for activating a main guage panel diagnostic. When I followed the instructions, all of my guage lights start blinking, I receive an "error 1" message. Does msantos (or anyone else) know what an "error 1" is? Thanks.

"There is a self diagnostics mode for the main gauge panel that you can try. Do the following to evoke the test:
1- press and hold the SEL/RESET button
2- turn the headlights ON
3- Turn the ignition ON to (II)
4- within 5 seconds turn the headlights OFF, then ON, then OFF
within 5 seconds release the SEL/RESET button, then push and release the button 3 times repeatedly.
5- use the SEL button the iterate through the tests.
If you turn the igntion Switch to OFF then the test ends."

Error 1: F-CAN communication
Error 2: B-CAN communication
Error 3: UART communication
Error 12: F-CAN and B-CAN communication
Error 13: F-CAN and UART communication
Error 23: B-CAN and UART communication
Error 123: F-CAN, B-CAN, and UART communication.

What is going on with your car that made you put it into diagnostics mode?

I tried the diagnostic mostly for curiosity purposes. Would you be able tell me what "f-can communication" means?

Most likely the car has two CAN networks. One high-speed for communication with engine module, transmission, ABS, and such. One low-speed for communication with the rest of the units, not requiring high speed - such as climate control, audio, doors, etc. The gauge panel needs connection with both networks.

I had a feeling you were going to ask that. Unfortunately, I have absolutely no idea what it means. rgx seems to have a better understanding that I do.

This is what is in the manual, it didn't really help me though:

If the word "Error 1" is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the fast-controller area network (F-CAN). Check for DTC in the PCM and troubleshoot and DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A.
If you have an OBDII scanner or other fault code reader, try and get the codes and I can tell you how to fix them. You also need a fault code reader to do the B-CAN system Diagnosis Test.
If you do not have a scanner, the manual says do this:
1. Check fuse No. 23 (10 A)
(the rest of the steps reqquire an MPCS service connector that you probably do not have, so I'm not going to type them.



Or.... you could just take it to your dealer.
I'm not sure what your 'symptoms' would be tho.
