Q: Replaced dead battery and now nothing but dash lites

asked by on

Replaced battery and car won't do anything. Did this 8 yrs ago whe I replaced battery but took 3 days for computer to learn. There must be a way to have the computer to learn faster.

My car has 50000 miles.
My car has an automatic transmission.

Hi Charles. Typically the ECU doesn’t take three days or any extended period of time to reset after replacing a battery. It is quite possible that an error code is stuck in the ECU causing the dash issues. To remove the code, it’s best to have a professional mechanic complete a check engine light inspection.
