Q: Q: I put a new battery

asked by on

I change battery and the service charge battery came on

My car has 160000 miles.
My car has an automatic transmission.

When you took the old battery out, the vehicle of course experienced a black-out or power interruption. That may have set a trouble code and it just hasn’t yet cleared. As a routine matter, whenever you put a new battery in, the charging system output (capability) should be tested just to be sure that charging system faults did not play a role in premature failure of your old battery. Also, if the charging system is not working properly, that could set the trouble light. Finally, if the battery was not fully charged prior to installation, that could cause the PCM to think the battery is faulty once a load is put on it. The best thing to do is make sure the battery is fully charged, erase the trouble code and see if the problem recurs. Also, be sure the battery terminal connections are spotless and mechanically secure. If the trouble light persists, the diagnostic to request is a battery trouble light diagnostic. The responding certified mechanic will identify the issue causing the fault if you request that diagnostic.
