Auto headlight leveller light came on
 
Morning all, hit a major pot hole yesterday on the way home, it has brought on a light on the dash that I had never seen before. Turns out to be the auto headlight leveller. Has anyone had experience with this. Could the pot hole cause this issue?

Yes and Yes!

Check the links on the sensors front and rear as these have a habit of breaking - also try a reset procedure:

When parts related to the auto headlight beam leveler system are removed or replaced, perform the following procedures to initialize or reinitialize.

NOTE:

Before performing initialization or re-initialization, check the following:

• Vehicle is parked on a level surface.

• The inflation pressure of tires is correct.

• Unload any cargo from the vehicle.

• Vehicle’s fuel tank is fully filled.

• Refer to the following chart to determine whether to initialize or reinitialize.

Initialization

• When the auto headlight beam leveler control module has been replaced with a new module.

Reinitialization

• When the auto headlight beam leveler control module has been replaced with a part from a different vehicle.

• When suspension parts have been removed or replaced.

(Cross member, front arm, housing, lateral link, strut)

• When the vehicle height sensor has been replaced or removed.

1. INITIALIZATION

1. Confirm that the indicator in the meter is repeatedly flashing twice.

2. Bounce the vehicle several times to normalize the suspension.

3. Make certain that someone is seated in the driver’s seat.

4. Turn the ignition switch to ON, and, within 1.5 — 20 seconds, turn the headlight switch OFF ⇒ ON three or more successive times.

5. Confirm that the indicator in the meter flashes three times and turns OFF, completing the initialization. (At this time, the headlight beam drops once, and then returns to the original position.)

6. Perform beam adjustment for the headlight.

2. REINITIALIZATION

1. Bounce the vehicle several times to normalize the suspension.

2. Make certain that someone is seated in the driver’s seat.

3. Turn the ignition switch to ON, and, within 1.5 — 10 seconds, turn the headlight switch OFF ⇒ ON five or more successive times.

4. Check that the headlight beam drops once, then returns to normal.

5. After confirming 4), turn the ignition switch to OFF within 30 seconds.

6. Turn the ignition switch to ON again, and, within 1.5 — 10 seconds, turn the headlight switch OFF ⇒ ON five or more successive times.

7. Make sure that the indicator in the meter flashes three times and then turns OFF, indicating that reinitialization has been successfully completed. (At this time, the headlight beam lowers once, and then returns to the original position.)

8. Perform beam adjustment for the headlight.

CAUTION:

If the indicator does not flash three times or the headlight beam does not operate, it can be assumed that there is an open circuit or faulty wiring in the harness of the headlight beam leveler control module, rear vehicle height sensors or headlight assembly. Perform inspection and repair according to the inspection results, then perform initialization/reinitialization again.

Thanks for the info, checked front and rear sensors, rear is fine, front has had water in it, corroded one of the pins and after a clean up i noticed it's stuck in the other part.
