Omega General Help / Xenon Headlight ECU / Tech 2
« on: 23 December 2019, 17:19:20 »
After having replaced both Xenon headlights, Tech 2 is no longer able to communicate with the headlight levelling system ("No Communication With Vehicle").
Communication with other systems work fine.
I also get an intermittent error message for malfunctioning headlight levelling system on the information screen in the car.
My first idea was that the front levelling sensor was causing this but then again, even if the sensor has gone bad, Tech 2 should still be able to communicate with the system?
Does anyone know the location of the Xenon Headlight ECU (GM part No. 90 565 31)? Maybe this part is creating the problems?
Any advice and suggestions will be greatly appreciated
