Accessing - EOBD type<br />

<strong>Trouble</strong> codes can only be displayed by using diagnostic<br />

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

Erasing<br />

Ensure ignition switched OFF.<br />

Disconnect battery earth lead for 30 seconds minimum.<br />

Reconnect battery earth lead.<br />

NOTE: Disconnecting battery may erase memory from electronic<br />

units (e.g. radio, clock).<br />

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

erased using diagnostic equipment connected to the data<br />

link connector (DLC).<br />
