Auto Leveling HID - Stepper motor short to ground
Hi All,
- My auto-leveling HID headlights are not raising up to the right level (not moving at all).
- OBD2 scan reports: B2611 - Right headlamp stepper motor circuit - short to ground
- OBD2 reports sensible readings for both front and rear level sensors (that feed into the auto-levelling unit)
- I've checked the feed to the headlight unit - no shorts to ground on any of the 4 stepper motor outputs at the headlight connector
- I've checked the resistance on the two stepper motor coils (4 terminals) inside the headlight - 12.5 Ohm across both circuits, and no short between circuits
Any bright ideas what the issue might be? I haven't checked anything in the auto-leveling unit itself - but not sure what I could realistically test in there.
Could swap left and right headlights to confirm if the problem stays on one side or swaps over... but that invovles removing the bumper
Cheers!

Percussive maintenance did the trick for now! Thanks @tberg
