have a 95 k1500 no reverse tried to scan ecm no data came up on otc 4000e.
I can flash codes they are 66,67,83. not sure how tell if they are eng or trans.
my book dosen't tell me my scanner dose that. so i'm kind of lost maybe some one has code list for 95 k1500. does any one have idea why i can't scan the ecm. I was told the sun shell is bad but they tell me they need the codes to make sure the electronics are working ok.
thank you

bumping this for you.

I tried the link but the codes for vin k only go to 55 what did you look under.
also the no data from my scan tool could it be connected to the short to cig. lighter fuse. I donot have a diagram of that circut.

I finaly scanned it with my tool but it said 83 not used.and the tcc light is on all the time . I must have bad connection because when road test you loose data intermitantly?
