So recently my corrola had died. And whilst trying to jump it my bud had his wires crossed and my horn went off. After trying to jump it several other times I came to the conclusion that either the alternator or batter had gone bad. So I replaced both. Now the car turns on fine. But electronics wont work. On the dash the abs, air sensor light, airbag, steering, skid,and brake lights are on. Car wint shift into drive. Ac doesnt work. Only hazards work, not individual blinkers. Is this a ECU problem? I have one ordered and on the way, I’m just hoping I didnt waste money
You spent a good amount of money on a battery and an alternator without even putting a voltmeter on the old ones. To me, that doesn’t demonstrate good judgement.
Connecting the cables backwards usually causes fuses to blow. Check all of the fuses in the engine room fuse block. There is also a large grid fuse under a clear plastic cover, inspect for any blown segments.
Battery died twice before, wouldn’t start while jumped, or double wired to another car. Battery would hold the charge. Two faults that seem text book bad alternator for not being able to stay on after a jump, and bad battery for not being able to hold charge from a remote pack
Thank you for the assistance and input. That was very enlightening and comprehensive way to help me figure out what’s wrong, as a forum would. If there was a rating system, I’d give you a 10
