NO COMMUNICATION
Posted to Technical Discussion Forum on 1/14/2016 11 Replies

this rover is driving me batty, came in another shop installed a used motor for a no start, ? when we got it there was no pcm communication, the data line only had 6.5v, not the 10.5 needed for proper communication, removed all other modules from the line, still no communication, can communicate with all other modules, and the all have code for pcm communication, has all the powers and grounds, all 5v from pcm are there, sent computer off, was told pcm no good, we tried a used one(knowing that it would not work because off no being able to reprogram the vin), but was hoping for communication, nothing, what im wondering is does the security system affect the computer waking up? any help would be great, need this truck gone!
