Checking High-Pressure Washer Pump

Check that the fuse for the high-pressure washer is intact.

Disconnect the pump for high-pressure washing from its connector.

Try to activate the headlight washers with the lever.

If the fuse does not fail when the washer pump is disconnected, the cause of the trouble code being set is probably an internal short circuit in the washer pump for the headlights. Try with changing high-pressure washer pump.

If the fuse fails, even if the pump is disconnected, the pump is probably okay. Continue troubleshooting.
