Checking Status

Activate the rear fog lamp.

Check if the fault is permanent or intermittent.

The rear fog lamp must light on activation.

The fault is permanent if the rear fog lamp does not activate.

If the rear fog lamp is activated, this is an indication that the fault was present previously but that it is not active at the moment, i. e. the fault is intermittent.
