Default Reduce Power, Service Traction Control?

Pulled up to the light yesterday and a reduce power, service traction control popped up. Car would idle, but wouldn't drive. I restarted it, same error, tried again two more times and finally was able to drive home. 1998, Conv 68K miles.

Current codes I had were:
A1 - RDCM B2265H
40 - BCM B2723H
28 - TCS C1278H
10 - PCM P1518H

Did some forum searches and it seems all over the place. From right or left door error, mirror, steering wheel, battery/Voltage, etc. I did recently have the harmonic balancer replaced and I hope they didnt mess up the steering wheel alignment sensor. I had that code pop up right after the work, but not seen any issues.

Any thoughts? I drove it the rest of the day and no issues. Put it on the charger as I normally do over the winter. Battery is not about 7-8 yrs old, so may be battery?

Barry.

Many times the cause of the problem is never found, I have also had this occur to my 97, and I disconnected the battery for 10 minutes or so, you might want to put a DVM across the battery terminals and verify that it is at 12.5. Our cars are very sensitive to low voltage conditions.

Thanks all. I drove it yesterday and not one issue. I'll replace the battery this weekend. I see Costco has Interstate too.

AGM batteries are much less likely to leak and destroy wiring harness below the battery or the PCM.
