Toyota Repair Problems? Ask a Mechanic for Answers ASAP
hi my name is ***** ***** I help you, what was the original problem with the a/c? and did it work before the part replacement? any codes before the job ?
ok multiple codes and reset right away after clearing them means it's a hard code situation. give me time to investigate and get back to you
OK THESE CODES ARE ALL RELATED TO THE a/c CONTROLS AND GIVEN IT WORKED BEFORE THE JOB AND NO CODES AND NOW IT DON'T WITH THESE CODES AND THEY RETURN EVEN AFTER ECU RESET TELLS ME IT'S A HARD CODE WHICH MEANS SOMETHING IS DAMAGED OR NOT CONNECTED PROPERLY. SORRY TO SAY YOU WILL HAVE TO OPEN IT UP SO YOU CAN CHECK ALL THE CONNECTIONS AND MAKE SURE THEY ARE ALL CONNECTED AND PROPER. HOPE THIS HELPS.DID YOU DO THE JOB YOURSELF OR A REPAIR SHOP?
The controller won't set off those codes, and they were not there before the job was done and now they are. what usually sets off a hard code is an open or short circuit that the ECU detects immediately. this is why I suspect a connector was left unplugged or loose , the connectors at the a/c box have many wires going through them . If one connector is loose or not connected that would set that many off.
well if your positive all connectors are connected it's hard for me to check further so I'll pass on to another tech and hope you find what your looking for.Good luck
