Jaguar XJ (X350). Manual — part 212

Electric parking brake module connector 1 (CR50) disconnected. 3. Key on, engine off. 4. Measure the

resistance between:

CR50 connector, harness side

Vehicle battery

Electric parking brake switch release 1 - signal - Pin 11 Negative terminal

•

Is the resistance greater than 100 Kohms?

-> 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

-> No

GO to Pinpoint Test
