So I decide that along with replacing the heater core, in the name of routine maintenance,I'll check for any codes and reset. The only code I got was from socket A3, and it was a 1-4-4. That's was kind of odd, I could not im,agine when that happened. So I simply cleared the code.

So I disconnect the battery, replace the heater core, reconnect the battery and restart the car. Now the ABS light is on. Hmmm. I checked for codes, A-3 is still 1-1-1. So I tried clearing it again anyway, still I have an ABS light and a 1-1-1.

What happened?

Did you drive the car yet? The ABS system does a self check at close to 20mph and will turn off the light if all is OK. The 1-4-4 could have been a left over which is why everyone with a pre 1996 should check and clear codes at every oil change.

That was it! 2 blocks, and the light was off.

Nope, too many beers this afternoon. I'll drive it tomorrow and see what happens.
