Engine control module (ECM) displays all available<br />

diagnostic information for immobilizer system.<br />

n Transmission control module (TCM) mounted separately.<br />

0 Data bus connecting ECM to TCM allows faults relating to<br />

both systems to be displayed when accessing ECM fault<br />

memory.<br />

il The ECM/TCM fault memory can also be checked and<br />

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

link connector (DLC).<br />

Accessing<br />

Ensure ignition switched OFF.<br />

Bridge data link connector (DLC) terminals GND and<br />

TEN a.<br />

Connect LED test lamp between terminals FEN and B+ O.<br />

NOTE: Connect LED test lamp positive connection to DLC<br />

terminal B+.<br />

Switch ignition ON.<br />

Count LED flashes. Note trouble codes. Compare with<br />

trouble code table.<br />

Two digit trouble codes are displayed as follows:<br />

n Long flashes indicate the 'tens' [A].<br />

Short flashes indicate the 'units' rn [C].<br />

For example: <strong>Trouble</strong> code 12 displayed H.<br />

Four digit trouble codes are displayed as follows:<br />

n Each trouble code consists of four groups.<br />

A long flash indicates the start of each group [A].<br />

Short flashes indicate the digits of each group [B].<br />

n No short flashes in a group indicate '0'.<br />

n For example: <strong>Trouble</strong> code 0120 displayed El.<br />

Switch ignition OFF. Rectify faults as necessary.<br />

Erasing<br />

Ensure ignition switched OFF.<br />

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

Depress brake pedal for at least 20 seconds.<br />

Reconnect battery earth lead.<br />

Repeat checking procedure to ensure no data remains in<br />

ECM fault memory.<br />

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

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