- What I Drive
- 2015 Ford Focus SE
2015 Focus SE 2.0 flex fuel
I was in the process of changing out / upgrading the head unit ( radio/screen) when everything went crazy when the battery voltage dropped too low and the car had a hissy fit. Not sure if it was something I did or the voltage drop but the front wipers stopped working even after I returned everything back to factory parts
these are the codes it is throwing and additional details
BdyCm: B101E:23 <<---Air Conditioning Mode Switch -Signal Stuck Low
B1089:23 <<---- Blower Control -Signal Stuck Low
B1131:87-2F <<<-----windshield wiper motor communication failure (specifically a missing or corrupted LIN bus message/signal between the Body Control Module and the wiper motor)
does anyone know the location of both ends of the LINbus Wire ( I believe to be gray with violet or purple strip ) go to (what conector where and what pin numbers i should check and test??
the photos are of my bcm for reference and I do have Forscan as well as the ODBII adaptor so I should be able to make changes and adjustments
Any info would help
sorry forgot info from Forscan
