Having problems with your 1995 Chevrolet Lumina ?
I have been trying to retrive the DTC's from my 95 lumina. I tried the OBD-I process, but the MIL did not flash the codes. I bought an CAN OBD-I & II tool, but the reader tells me that the tool is not comunicating with the vehical. how does one retrive these codes from this model?
On some 1995 OBD 1 models with a 12-pin Data Link Connector, trouble codes can be accessed by connecting terminal B to terminal A with a jumper wire. With the key in on position, the codes can be read by watching the "service engine soon" light. HOWEVER, some models have a 16-pin DLC and you have to jump terminals 5 and 6 to get the trouble codes to flash.
