Code P2610 was more than likely set when you disconnected your battery. Clear the code or it will turn off after 3 good drive cycles. See below.
P2610-PCM INTERNAL SHUTDOWN TIMER RATIONALITY TOO FAST
Theory of Operation
The PCM shutdown timer is compared with the main processor timer shortly after the engine has started. If there is a difference between the two timers, then a fault is set. This is a two trip fault to set the MIL. If the battery is disconnected for more than 60 seconds then the power supply that maintains the shutdown timer is lost, and so a pending fault will be set the next time the battery is re-connected and the PCM powered up.
When Monitored:
On power up, the check is made for the battery disconnect, and then 5 seconds after the engine has started the timer check is evaluated.
Set Condition:
A greater than 60 second battery disconnect or a difference between the two internal PCM timers. Two trip fault. Three good trips to turn off the MIL.
