I updated the pdf to reflect differences between early C5s (1997 to 2000 model years) and 2001 to 2004 models

Under the antilock/traction control system have you got C1225 and C1226 reversed? I have heard from other sources that the C1225 is the Left front and C1226 is the right front.

You are correct. C1225 is for the left.

It's not a complete list for all C5's. Many 2004 codes are missing.

I didn't realize that 2004 had additional DTCs. I will look into that and correct the pdf if justified.
Also the pdf ha sbeen revised to show C1225 is LF and C1226 is RF.

Not additional......different. For example: on a 97-03, the an AIR check valve malfunction is a P1415 or P1416. On a 2004, the same malfunction is P0491 or P0492.

The P2761 DTC listing and description should be green color-coded.

Thanks. The code is preceded by # and part of the line is green, so it is half a$$ correct - lol

. I'll get it fixed and repost.

Looks great!

I have them all printed to use for a quick reference when needed.

The color-coded lines, for specific model years, is a big plus.

Thank you for this list, it has been very helpful!

One question though:
C1272 is suppose to be a code specific to 1997 through 2000 model years..?
So if you have a 2003, with that code, how are you suppose to interpret that? Bad DTC version?
