ECM keeps internal counting to calculate the model values related to temperature under IG "OFF" condition. ECM uses this values to improve efficiency when the engine starts again.
If The deviation between the value by LPC and the value by internal counting is over 20 sec or ECM detects an error on internal memory, ECM sets P2610.
