Erasing Method 2<br />

Ensure ignition switched OFF.<br />

Method 1<br />

Disconnect battery earth lead for 10 seconds.<br />

Switch ignition ON.<br />

WARNING: Disconnecting the battery may erase memory from<br />

Connect LED test lamp between data link connector (DLC)<br />

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

terminal C3 <strong>and</strong> battery positive O.<br />

Bridge data link connector (DLC) terminal C2 <strong>and</strong> earth with<br />

a switched lead - contacts normally open O.<br />

Operate switch for 2,5-5 seconds.<br />

LED or MIL will now flash trouble code 12.<br />

Repeat switch operation until code 11 is displayed.<br />

Operate switch for 10-20 seconds.<br />

Switch ignition OFF.<br />
