hi. the car when you take off from a stop, occasionally the TCS will go off for no reason. no ice, not hard acceleration. the mechanic that normally works on this has changed the ABS harness on the front passenger side, did not correct problem.


i ran the codes that the car gives you by holding off and the red temp button.

i got....
PZM---B0533-Current; B1552-History, B1558-History; B1983-History; U1016-History
ACM---U1016-History
SDM---U1016-History; U1040-History; U1255-Current; B1327-History
TCS---C1276-History; U1016-History
PCM---P0603-History
IPC---B1552-History; B1983-History; B2750-History; B2750-History; U1255-History; U1016-History

it also displays ECM?

any help will be very appreciated, thank you.

 

You need factory book or online manual. Check grounds 102 and 103.Check ebtcm connector for corrosion. You may need PZM - sum error code in history.U1255 data line fault.

 

where is the PZM located, where is the EBTCM located, also the grounds location?

do you think that the EBTCM may need replaced as well?
