DTC |
C1569/69 |
Lock Mechanism Release Incomplete |
DESCRIPTION
The VGRS actuator contains a lock mechanism that mechanically locks the DC motor so that the motor will not rotate if a failure occurs or when the engine is not running. The VGRS ECU supplies current to the lock solenoid to release the lock lever for VGRS operation.
When the VGRS ECU detects a malfunction in the lock mechanism, it turns the warning light on and records the DTC.
