Jaguar XJ (X350). Manual — part 213

CR32 connector, harness side

Vehicle battery

Electric parking brake module - ground - Pin 13 Negative terminal

•

Is the resistance less than 10 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

-> No

REPAIR the open circuit. For additional information, refer to the wiring diagrams.
