Continuing to calculate data of several sensor despite turning ignition OFF, when ignition turns ON, ECM enables turning ignition ON to be easy using calculated data.
If abnormal counterdown is detected for a calibratable time, ECM sets P2610. And then MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycles.
Item | Detecting Condition | Possible cause | |
DTC Strategy | Case1 |
•
Compares the time elapsed recorded by the LPC(Low Power Counter) against that recorded by the test timer | 1. ECM 2. Poor Battery Condition 3. Connecting condition |
Case2 |
•
Checks for abnormal resets of the LPC | ||
Enable Conditions | Case1 |
•
Engine running > 10sec.
•
Battery voltage > 8V | |
Case2 |
•
No Memory Failure Occurred | ||
Threshold value | Case1 |
•
The difference between the counter the LPC and the calibration the test timer clocks up > 20sec. | |
Case2 |
•
The LPC is reset to zero abnormally | ||
