Carry out road test for at least 10 minutes. If engine does not start: Crank engine for 6 seconds. Leave ignition switched ON. Accessing The engine control module (ECM) fault memory can only be accessed using diagnostic equipment connected to the data link connector (DLC). NOTE: DLC terminal 1 is not connected to ECM terminal 11. Erasing Ensure ignition switched OFF. Disconnect ECM multi-plug or battery earth lead. NOTE: ECM adaptive memory may be erased causing erratic running faults. Carry out road test to allow ECM to re-learn basic values. Diagnostic equipment can also be used to erase data from ECM fault memory. WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio, clock).

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 />

Carry out road test for at least 10 minutes.<br />

If engine does not start: Crank engine for 6 seconds. Leave<br />

ignition switched ON.<br />

Accessing<br />

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

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

link connector (DLC).<br />

NOTE: DLC terminal 1 is not connected to ECM terminal 11.<br />

Erasing<br />

Ensure ignition switched OFF.<br />

Disconnect ECM multi-plug or battery earth lead.<br />

NOTE: ECM adaptive memory may be erased causing erratic<br />

running faults. Carry out road test to allow ECM to<br />

re-learn basic values.<br />

<strong>Diagnostic</strong> equipment can also be used to erase data from<br />

ECM fault memory.<br />
