DETECTING CONDITION AND POSSIBLE CAUSE





REFERENCE

- Connect oscilloscope between terminals 022-2 (+) and C22-10 (-) of ECM connector connected to ECM and check CMP sensor signal.

DTC CONFIRMATION PROCEDURE
1. Clear DTC and crank engine for 2sec.
2. Select "DTC" mode on scan tool and check DTC.





INSPECTION

NOTE: If starter circuit is open (i.e., start signal circuit is OK but starter fails to run), this DTC is stored in memory at starter switch ON, even though CMP sensor is in good condition. When starter motor fails to run and this DTC appears, check starter circuit first.
