Type of diagnosis:
- Continuous

Enable criteria:
- Ignition ON.

Fault criteria:
- Voltage on the control module output is below 6 V.

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
