Transmission<br />

General information<br />

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

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

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

Accessing and erasing<br />

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

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

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

<strong>Trouble</strong> code identification<br />

Scanner Fault location<br />
