General information<br />

Refer to the front of this manual for general test conditions,<br />

terminology, detailed descriptions of wiring faults <strong>and</strong> a<br />

general trouble shooter for electrical <strong>and</strong> mechanical faults.<br />

Vehicles fitted with a coded keypad: When switching on<br />

ignition or entering start code ensure diagnostic equipment is<br />

disconnected from the data link connector (DLC).<br />

Accessing <strong>and</strong> erasing<br />

The engine control module (ECM) fault memory can only be<br />

accessed <strong>and</strong> erased using diagnostic equipment<br />

connected to the data link connector (DLC).<br />

The following scanner codes are applicable to the fuel<br />

system manufacturer's test equipment, similar <strong>and</strong> more<br />

detailed fault diagnosis information can be obtained using<br />

the vehicle manufacturer's or equivalent test equipment.<br />
