parking brake incohearance fault

[retgar2002]

hi all thanks for reading, any advise would be greatfully recived, my 2014 C4GP developed a problem with ABS sensor on the rear left wheel, and a Parking brake fault, DIAGBOX reports RH parking brake incohearance the abs fault was caused by a corroded wire in the LH rear arch that has been fixed, but I can not find the fault with the parking brake on the RHS, it has since ran out of MOT. (due to no parking brake) the brake lights are also permanently illuminated, I suspect the problem is wiring related so im looking to get a wiring Diagram from the ABS/BSI module the the rear, and a pin out of the ABS/BSI module so I can run a new set of wires to the rear RH parking brake to confirm this is at fault or if its the ABS unit its self the vehicle identification is VF7**************[VIN obfuscated, can be read by forum staff]

Here you go:

Most of the codes are on the wiki:

Wiki Wiring Codes





Here's the connections with Harnesses. Don't pay too much attention to the wiring colours as they often and do change - focus on the Pin out Connections.
