DETAIL The wiring for the Center High Mount Stop Light (CHMSL) in the upper tailgate harness may be pinched by one of the screws that secures the panel shelf extension to the vehicle body. When this happens, the CHMSL shorts and blows Fuse 17. This results in a disabled shift interlock system and a vehicle that is stuck in PARK. Taping the CHMSL wires inside the trim piece away from the screw will prevent this from happening. PROCEDURE Disassembly 1. Disconnect the negative battery terminal. 2. Open upper tailgate. 3. Release load space lamp from the trim panel, disconnect the electrical connectors and remove the lamp. 4. Remove six Phillips screws securing the trim panel to the upper tailgate (illustration). 5. Release the 4 studs securing the trim panel to the upper tailgate. 6. Disconnect the stop lamp connector. 7. Remove trim piece. 8. Inspect the wires and repair if necessary

The Multi-Tester Pro can resynchronise the following replacement ECUs on LandRover vehicles: – • MEMS 1.6 • MEMS 1.9 • EDC Diesel
• Td5 Diesel • Motronic M5.2.1 V8 Petrol • GEMS V8 Petrol • Range Rover body controller (BeCM). When an engine management system is replaced, the new unit must be resynchronised to the immobiliser ECU. 1) Procedure for all except EDC Diesel Robust and non-robust mode On vehicles fitted with an alarm / immobiliser a coded exchange takes place between the immobiliser and the engine ECU when attempting to start the vehicle. If the code sent by the Immobiliser does not match the expected code stored on the engine ECU, the engine will not be allowed to start. This is known as robust mode.

There are many problems with the BeCM (Body Electrical Control Module) fitted to late model (from 1995) Range Rover and Discovery. Click here to see photographs of this unit. The BeCM controls virtually EVERY electrical function on the vehicle and problems within the
BeCM (or its associated fuse box) will cause mis-operation of vehicle electrical functions. When diagnosing electrical problems on vehicles fitted with BeCM, it is vital to appreciate the relationship between the BeCM and its associated electrical fuse box which is located in the engine compartment.
