Default P2610 & C1201 Codes

I was driving home and the TRAC OFF light came on and then the Check Engine light and the car drove fine all the way home.
Went to Autozone and got the codes P2610 and C1201.


I searched and P2610 didn't pop up for the LS 430. There was a tread with the LS 460 and the OP replaced the battery.
I checked my battery and it was 12.7 with engine off and 13.6 with engine running. The battery is 1 yr old from Costco.


I disconnected the negative last night and the light didn't come on this morning on my way to work.

Is your car an 06? I can only find this code listed for the 06 model.

Basically it appears to be a function of the PCM to monitor the Evap system when the vehicle is off. The only procedure is to clear it and see if it comes back. If it does it is saying that it's an internal problem to the PCM.
