When this circuit is shorted to the battery, it can cause issues with the proper functioning of the assist step, potentially leading to it not deploying or retracting as needed.
Common Causes of B052B:01
- Wiring or connector issues causing a short to the battery.
- Faulty position sensor.
- Water or corrosion damage to the circuit.
- Electrical issues within the assist step system.
- Defective control module for the assist step.
Symptoms of B052B:01
- Assist step not deploying or retracting properly.
- Warning light on the dashboard related to the assist step system.
- Unusual noises coming from the assist step mechanism.
- Assist step getting stuck in a certain position.
- Vehicle may not pass state inspection due to malfunctioning step.
How to Fix B052B:01
- Inspect wiring and connectors for any damage or corrosion.
- Check the position sensor for proper operation and replace if necessary.
- Test the circuit for shorts and repair as needed.
- Reset the system and calibrate the assist step position.
- Clear the diagnostic trouble codes and test the system for proper operation.
