If The deviation between the value by LPC and the value by internal counting is over 20 sec or ECM/PCM detects an error on internal memory, ECM/PCM sets P2610.
Item | Detecting Condition | Possible cause | |
DTC Strategy |
•
ECU internal engine off timer performance check | 1. ECM/PCM 2. Battery low-voltage | |
Enable Conditions | Case 1 |
•
Power down time | |
Case 2 |
•
Engine running | ||
Threshold value | Case 1 |
•
Compare the frequency difference between CPU & PCA8565(Soak timer) for power down time
•
I Timer frequency - CPU frequency | > 9.5% | |
Case 2 |
•
Compare the time counter difference between CPU & PCA8565(Soak timer) every 40 sec.
•
I Timer counter - CPU time counter | > 9.5% | ||
Diagnosis Time |
•
