Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hi, my name is***** also have a brake light relay and a bulb failure monitoring unit in the brake light circuit. You need to test the relay and test for voltage to the bulb failure monitoring unit when the brake pedal is pressed. The relay and the monitoring unit are located in the left rear of the trunk behind the trim panel.
I can help you with the testing. It would be easier if we spoke on the phone.
