General information<br />

Refer to the front of th~s manual for general test cond~t~ons,<br />

termmology, detaded descr~pt~ons of wlrlng faults <strong>and</strong> a<br />

general trouble shooter for electrical <strong>and</strong> mechan~cal faults<br />

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

The transmission control module (TCM) fault memory can<br />

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

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