Checking ECM/PCM under detecting condition, if internal error is detected, ECM/PCM sets P0606. And MIL(Malfunction Indication Lamp) turns on.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 |
•
IC diagnosis of evaluation IC (CJ125) for linear upstream O2 sensor check | 1. Poor connection 2. ECM/PCM |
Case 2 |
•
Diagnosis of power supply module(CY320) check | ||
Case 3 |
•
IC diagnosis of IC (CY202) for fuel volume control module check | ||
Enable Conditions |
•
- | ||
Threshold Value | Case 1 |
•
Operating voltage at CJ125 too small
•
Write error at INIT register of CJ125
•
Communication error of SPI interfaces to CJ125 | |
Case 2 |
•
SPI communication error of CY320 | ||
Case 3 |
•
Internal error with SPI communication to CY202 | ||
Diagnostic Time |
•
Continuous | ||
