7. Operating Instructions
The power running board motor operates automatically in conjunction with your vehicle's door sensors. Once installed correctly, the running board will function as follows:
- Deployment: When the corresponding vehicle door (driver's side in this case) is opened, the running board will automatically deploy to its extended position.
- Retraction: When the corresponding vehicle door is closed, the running board will automatically retract to its stowed position beneath the vehicle.
Ensure there are no obstructions in the path of the running board during deployment or retraction to prevent damage to the motor or the running board itself.
8. Maintenance
To ensure the longevity and optimal performance of your power running board motor, consider the following maintenance tips:
- Regular Inspection: Periodically inspect the motor and bracket assembly for any signs of damage, loose connections, or excessive wear.
- Cleaning: Keep the motor and surrounding areas free from excessive dirt, mud, salt, and debris. A gentle wash with water and mild soap, followed by thorough rinsing, can help prevent corrosion.
- Lubrication: Consult your vehicle's service manual or a professional mechanic regarding lubrication requirements for the running board's pivot points and moving parts. Avoid lubricating the motor itself unless specifically instructed.
- Wiring Check: Ensure all electrical connections remain secure and free from corrosion.
9. Troubleshooting
If you experience issues with your power running board motor, refer to the following common problems and solutions:
- Running Board Does Not Deploy/Retract:
- Check all electrical connections to ensure they are secure and free from corrosion.
- Inspect for any physical obstructions preventing movement.
- Verify the vehicle's battery has sufficient charge.
- Check relevant fuses in your vehicle's fuse box (refer to your vehicle's owner's manual).
- Unusual Noises During Operation:
- Inspect for debris caught in the mechanism.
- Check for loose mounting bolts on the motor or running board.
- Consider if lubrication is needed for the running board's pivot points (not the motor itself).
- Intermittent Operation:
- This could indicate a loose electrical connection or a failing sensor. Recheck connections.
- Ensure the door sensor is functioning correctly (if applicable to your vehicle's system).
If troubleshooting steps do not resolve the issue, it is recommended to consult a certified automotive technician.
