I've been searching on the following error codes that my 2002 Z06 just started throwing. I have owned the car since new......it is garage kept and only has 10k miles. I have reset the codes and they keep coming back each time i drive it. It appears to throw the codes under heavt acceleration . I have searched some on the forums and see various possible reasons but wanted to post up here to see what yaw think? Didn't know if there might be a common ground for all these?

28-TCS - Traction Control System
C1225 RF Excessive Wheel Speed Variation
C1232 LF Wheel Speed Circuit Open or Shorted ​
C1233 RF Wheel Speed Circuit Open or Shorted
C1248 IPC Indicated Low Brake Fluid​

A0-LDCM - Left Door Control Module
U1064 Loss of Communications with BCM

A1-RDCM - Right Door Control Module
U1064 Loss of Communications with BCM

Thanks for any help!

Thanks 8VETTE7! I'll take a look at those!

I also found this post with some of the same error codes late last night........ended up being a bad EBCM.

Although it looks like he was not throwing a C1225.

Guess if i can't find any bad grounds or connectors then i will replace the EBCM.

Thanks 8VETTE7! I will checkout the wiring and connectors on both front wheel speed sensors. Yea....i was hoping it was NOT something like the EBCM. I'll post back after i get a chance to inspect.

UPDATE*******

So last night i disconnected, checked, and re-connected both the LF and RF wheel speed sensor harnesses (4 connectors total). All the connectors looked good.

I drove the vette to the gym tonight.....no codes on the way to the gym as i drove calmly, but on the way home i got it to throw just the C1233 code. Each time it threw the code i would pull over.....check the codes (only C1233) then i would reset and try to get it to throw again. Interesting it was easily duplicated. All i had to do was pull out......nail it in 1st shift to 2nd nail it......then around 65mph it would throw the C1233 code. Did it 4 times in a row. Just throwing the C1233 code.

So i'm think'n replace the RF speed sensor harness......what yaw think?
