SOS- It is like anti theft is engaged!! Car was getting brake pads and now mechanic has called and said the system has shut down. He cant find answer!


Recommended Posts

Hello.

As described my car is in shop getting brake pads. The mechanic has called and said the good news is the brake pads are on but now my car will not work. He has called local dealer and talked to Canada and Michigan. They tell him to take the key and unlock the door so the car knows it is not being vandalized but that does not work. He has unhooked the battery for an hour and reconnected. They have checked all fuses. It has thrown no code. Does anyone have any suggestions. PLEASE HELP.

You need to provide more info, you say 'will not work', what exactly happens, any messages?

I assume the battery tested OK?, did they leave the door open during the work?

Check the battery connections

And check for DTC codes that are set, follow the directions here

Thank you for responding. The mechanic says he has checked the battery. He says the dome lights work, the radio works and the rear lights work and nothing else. He says no codes are shown and that the computer system is shut down. He now says he is going to tow it to he dealership and that they are going to reboot the computer. What do you think?

MYSTERY SOLVED- He called and said 3 screws on some box over the fuse panel were not tight and when he tightened it down it made connection and the door open signal engaged and then he tried the ignition and she started. HURRAYYYYYYYYYYYYYY! Thanks for offering you help.

Glad you got it solved, not sure what he found, but glad he fixed it, have him show you what he tightened if you can
