What is this???

[TSPowell]

I was trying to read my hour meter, but accidentaly help the trip buttun down then turned the ignition on. The whole cluster light up, the tach and speedometer started bouncing around. At the end it flashed C Code then a bunch of numbers and some letters followed. It looked like it was doing a sytem check, but of what? I couldn't find anything in the service manual. Before you ask, NO it wasnt the normal check engine light codes... .

That is how you do a function & light bulb test on the instrument cluster. Those "C" codes are for the cluster, too.

Doest that mean I have cluster lights out somewhere?

Yes as stated you triggered the Instrument Cluster Diagnostics. The display shows a two digit code and a two number count. This is a list of Instrument Cluster codes that I have. I think this was from a 2003 manual so there might be new ones.

This explains it much better than I can. If you don't see any problems, don't worry about it.

 

[TSPowell]

This is what is flashes:

67 45

A5 15

A7 00

Ad 15

00 00

 

[TSPowell]

67 - All door unlock output circuit shorted to

ground or voltage.



A5 - TCCM messages not received.



A7 - VIN checksum error.



Ad - FCM messages not received.



Do I need to worry about these??

 

[JVolpe]

I just ignore them unless there is really something that is evident and related to the code. On mine I have seen codes like some of the above that were just there. Never had any indication that there was really a problem. I think mine were just glitches.



Let's put it like this; make out like you did not accidently find the Instrument Cluster diagnostic sequence. Would you be worried about something wrong with no indication of a problem?

 

[rbattelle]

In the list above, based on this thread, I believe A4 is an airbag module code rather than an ignition switch code.

Thanks everyone! It's threads like this that make the $35 annual membership fee worth every cent.
