Reset my coilover ride height and thought I’d check my headlight level. Set them the old fashioned way against a wall and then fired up Rosstech. When I attempt to access address 55 it times out. Ran a full auto scan and 55 is absent, went back over my old scans and realized 55 has never shown up.
I verified the module is plugged in behind the glove box, fuse location 10 is OK, front and rear sensors are present and plugged in, motors on headlamps are present. After an hour of going over all the coding I know how to do I can’t find anything out of order. Address 09 has the proper coding for Canada, light sensor and Xenon’s.
Contacted the original owner of the car and he told me he had the levellers coded out by a shop may years ago as he was getting random dipped headlamp warnings. The previous shop no longer exists and from what I can find there is no DIY or goggle info for coding the module out entirely.
Does anyone know how to code the module back in?
