Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site. let first check the dlc pins. pin 4&5 should be grounds. pin 7 should read 3.5vdc with key off and pin 16 should be B+
does the scan tool power up but just now comm?
ok. gimme a few
what kind of scan tool are you using?
heres a few print to help you out. maybe do some continuity checks of the data lines ans power lines.
in my opinion yes it would be, but i like to make certain that the wiring is good. but thats your call obviously. i would think it need reprogrammed. i just want to give you as many resources as i can
it is fairly normal on todays vehicles yes. now if you didnt have the appropriate readings and grounds at the dlc, i would think not. do this, disconnect the connectors at the computer and reconnect them. look at the grounds in the area also. make sure nothing is loose or corroded.
checking in to see if how its going
