VW Sharan (7N) Parking Brake

From Ross-Tech Wiki


Coding

Note: When replacing the Parking Brake Control Module it is necessary to save a complete Auto-Scan before performing repairs. The ABS Module coding will be lost when the Parking Brake Module is replaced. You MUST have a record of the existing coding or you won't be able re-code the ABS module!

  • A coding chart for this module will be available in a pop-up balloon when connected to the vehicle with VCDS.

Basic Setting

Caution!

  • Do not perform any of these Basic Settings while the brakes are disassembled! Opening, closing, function tests, and otherwise cycling the Electronic Parking brakes should only be done with the pads and calipers properly installed on the rotors.
  • Please follow the procedures EXACTLY. There's a reason for every step. If you skip any prerequisites or other steps here, you are likely to experience "issues" for which no documented resolutions exist, in which case we will not be able to help you resolve them.
  • It is strongly recommended to run a full Auto-Scan first thing to check for any preexisting faults! There have been several reports of repair shops damaging the Electronic Parking Brake System when trying to do rear brakes, but not telling the customer and then sending the car out the door.
