I found the list of IPC display codes on this site but I was wondering if someone could put these into laymans terms so I can understand exactly what is happening.

P0128HC--can't find this code in the list
C1221H--LF wheel speed sensor is 0
C1222H--RF wheel speed sensor is 0
C1248H--can't find this code in list

I think I know why C1221H & C1222H are present. The car was dynoed (rear wheels spinning & front static) and the codes were not reset.

The other two codes I couldn't find in the list. Could someone please enlighten me? :)

If I can't find it on our exhaustive list, I saunter over to corvetteplanet.com. They have a code list also. Two stops better than one?

Roger,

Click on the Owner FAQ on the left... THen the 2nd paragraph has a link to a Word document with instructions on getting the codes, and a list of what they mean.

The P0128 means ECT below thermostat regulating temp.

C1248 is right front ABS motor free spins.
The ones with just a H histoy, from dyno,
the P0128 though is still in C current state.

If you have like a Ease scanner, you can always find codes by doing a serach in the DTC library.
