Park Lock/Pawl Actuator Circuit Low
Voltage on the park lock or pawl actuator control line is below the expected window. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Affected components
- Park lock actuator
- Park pawl
- Wiring harness
Common causes
- High likelihood: Control wire shorted to ground
- Medium likelihood: Internal short in actuator coil
- Low likelihood: Connector pins corroded - high contact resistance
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
