When working on the Harrier ASU60/ASU65 interior lighting systems, it is easy to overload or short delicate microprocessor controlled circuits in the body control module. The modern interior lighting systems are highly integrated into the interior circuits and the best approach is to use the OEM wiring diagram. It provides circuit tracing, power and ground verification and connector identification throughout the cain lighting network. It details the electrical connections linking the main body ECU, door courtesy switches, map lights and dome lamp assemblies. It enables accurate tracking of switched grounding circuits and power supply lines
