Is the resistance less than 10 ohms? -> Yes GO to Pinpoint Test G531320t37 .
-> No REPAIR the open circuit. For additional information, refer to the wiring diagrams. G531320t37 : CHECK THE ELECTRIC PARKING BRAKE SWITCH 1. Measure the resistance between: TL82 connector, component side
TL82 connector, component side
Electric parking brake switch apply 2 - signal - Pin 07
Electric parking brake switch - switch return - Pin 06

Is the resistance between 595 ohms - 611 ohms? -> Yes An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other physical damage to the harness. If no fault is found in the circuit, suspect the following component(s): - EPB module - EPB module connector, CR50 - EPB module connector, CR32
-> No INSTALL a new EPB switch. Parking Brake Switch (70.35.46)
G531320t38 : CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE 1.
