Code: P0603

Code P0603 description: Powertrain control module
Keep alive memory (KAM)
Error

What?! Apparently my SES light came on due to long disconnection of the battery during the repair. Anyone know what to do with this? Resetting the ECU didn't get rid of the code.

P.S. I have a code reader and I'm tempted to erase the code. Is that a good idea?

If it's trigerred by something the repair shop had done why don't you take it back to the shop and let them figure it out?

That's fairly innocuous considering the battery was disconnected... I would be concerned if it came back after you cleared it, that would suggest a wiring and/or volatile memory fault.

The net result of this fault is that the ECU lost all of its long-term learned data. You accomplished the same thing when you reset the ECU, so it's a wash. Clear the code and see if it comes back.

Cleared. I'll see if it comes back. If so, I'm going back to the shop

Since it's a memory problem that showed up after disconnecting the battery, I'd say it's just a glitch that happened on power-up. Maybe there was some fumbling around when the battery terminal was reconnected. I'd go with Kaldaien's suggestion: clear the code and see if it comes back.
