Check engine light and codes.......
My check engine light came on and I wrote all the codes down. I searched for them on the internet and found most of them, but some I can't find and the H has me a little confused!
The codes with question marks next to, I couldn't find anything about. But even the codes I did find............I can't figure out what they are from or what sould be the cause
I'm hoping some of you might be able to help me or guide me in the right direction.
10-PCM
P0442 HC ???????
58-SDM
B1001 H ???????
60-IPC
U1160 H -Loss of Communications with LDCM
AO-LDCM
B2252 H -Key Cylinder Switch Fault
B2282 H -Battery #1 Fault
B2284 H -Battery #2 Fault
B2262 H -Horizontal Postition Sensor Fit
B2264 H -Vertical Position Sensor Fault
U1255 H -Serial Data Line Malfuntion
U1064 H -Loss of Communication with BCM
U1016 H -????????
U1096 H -Loss of Communication with IPC
AI-RDCM
B2283 H -Battery #1 Fault
B2285 H -Battery #2 Fault
U1255 H -Serial Data Line Malfunction
U1064 H -Loss of Communication with BCM
U1016 H -?????????
U1096 H -Loss of Communication with IPC
BO-RFA
U1096 H -Loss of Communication with IPC
U1064 H -Loss of Communtication with BCM
U1016 H -?????????
C2110 H -Right Rear TPM Sensor Malfunction
C2115 H -Left Rear TPM Sensor Malfunction
Okay, I found in my search that the "H" ant the end of the code means it occured in the past and that its fine now. Does that mean I can delete all the codes and everything should be good to go now?
And what about the "C" after the "H" on the PCM code. What does that mean?

Did you disconnect your battery recently? Those "Uxxx" loss of communication codes sometimes happen when a battery is reconnected as intermittent power is applied while attaching the terminal.
Clear them, and if they don't come back forget about it.

Yes the batery was disconected for quite a while (5 weeks to be exact)! I didn't even conect the two! Thanks for your post!
I'll clear the codes and see which ones come back!

C for Current, H for History. Good luck, when battery is weak or disconnected the PCM can get confused.

Hey 00'Vette,
I don't know if you still have your issue but try the following because I had a similar issue with mine.
In reality it was a poor ground which was a little bit un-screwed. more precisely the one which is just in the corner of the passenger door (in the front, just below the plastic trim)
Tell me if this is not clear ... my english is poor !!!
See you,
