Common Kneeling System Issues

Kneeling systems in handicap vans are crucial for accessibility, but they can sometimes malfunction. The most frequent problems include:

  • Complete failure to kneel
  • Intermittent kneeling
  • Slow or partial kneeling
  • Failure to return to normal ride height

These issues can significantly impact the van's usability and pose safety risks for passengers with mobility challenges.

Causes of Kneeling System Failures

Several factors can contribute to kneeling system malfunctions:

Electrical Problems

  • Faulty wiring: Loose connections or damaged wires can disrupt the system's operation.
  • Dead battery: A weak or dead vehicle battery may not provide enough power for the kneeling mechanism.
  • Blown fuses: Check and replace any blown fuses related to the kneeling system.

Mechanical Issues

  • Broken kneeling chain: The chain connecting the actuator to the suspension may be damaged or broken.
  • Worn actuator: The kneeling actuator might be worn out or damaged, preventing proper operation.
  • Seized components: Rust or lack of lubrication can cause moving parts to seize up.

Environmental Factors

  • Extreme temperatures: Both very hot and very cold weather can affect system performance.
  • Contamination: Dirt, salt, and debris can interfere with the kneeling mechanism's operation.

Troubleshooting Steps

Follow these steps to diagnose and potentially resolve kneeling system issues:

1. Check the battery: Ensure the vehicle's battery is fully charged and in good condition.

2. Inspect fuses: Look for and replace any blown fuses related to the kneeling system.

3. Clean the system: Remove any visible dirt or debris from the kneeling mechanism components.

4. Lubricate moving parts: Apply appropriate lubricant to hinges, chains, and other moving parts.

5. Examine wiring: Look for any loose connections or damaged wires and repair as needed.

6. Test manual override: If equipped, try using the manual override function to operate the kneeling system.

7. Reset the system: Some vans have a reset button or procedure. Consult your owner's manual for instructions.

When to Seek Professional Help

If the above steps don't resolve the issue, it's time to consult a professional. Consider the following:

  • Certified mobility dealers: These specialists have the expertise to diagnose and repair complex kneeling system problems.
  • Regular maintenance: Schedule bi-annual check-ups with a certified technician to prevent issues.
  • Warranty coverage: If your van is still under warranty, contact the manufacturer or dealer for covered repairs.

Preventive Maintenance

To avoid future kneeling system failures:

  • Regular inspections: Check the kneeling system components monthly for signs of wear or damage.
  • Keep it clean: Regularly clean the undercarriage, especially after exposure to salt or harsh conditions.
  • Lubricate routinely: Apply lubricant to moving parts as recommended by the manufacturer.
  • Address issues promptly: Don't ignore minor problems, as they can escalate into major failures.

By following these guidelines, you can help ensure your handicap van's kneeling system remains reliable and functional, providing safe and convenient access for those who depend on it.
