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 />

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

The enqine control module (ECM) fault rnemorv can onlv be<br />

accessed <strong>and</strong> erased using' dia&ostic equipment<br />

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