VLC 522311.06 – Rear Washer Pump Circuit Current High

VLC 522311.06 (VLC )

Code: 522311.06

Shortcode:

Description:

This error code, VLC 522311.06, indicates that the Vehicle Load Center (VLC) control unit has detected that the current in the rear washer pump circuit exceeds the fuse rating of seven amps. This suggests a potential short circuit or excessive load in the circuit.

Reaction:

When this fault is detected, the rear washer pump will not operate, and the circuit’s fuse may blow to prevent damage, leading to the rear windshield not being cleaned properly.

Recommendations:

Inspect Wiring and Connections:

  • Examine the wiring and connectors in the rear washer pump circuit for any signs of short circuits, such as damaged insulation or exposed wires. Repair or replace any faulty wiring or connectors.

Check the Washer Pump:

  • Ensure that the rear washer pump is not drawing excessive current due to a fault. Replace any faulty washer pumps.

Test the Relay and Fuse:

  • Verify that the relay and fuse for the rear washer pump circuit are correctly rated and not faulty. Replace any blown fuses or malfunctioning relays with the correct ratings.

Measure Circuit Current:

  • Use a multimeter to measure the current in the rear washer pump circuit to confirm it exceeds seven amps. Identify and rectify any sources of excessive current draw.

Consult Technical Support:

  • If the problem persists, contact technical support for further diagnostics. Provide detailed information about the fault and the steps taken to resolve it.

Note:

  • High current in the rear washer pump circuit can be caused by factors such as short circuits, mechanical faults in the washer pump, or incorrect component ratings. Regular maintenance and careful inspection of the electrical system can help prevent such issues.
