Erasing<br />

Method 1<br />

Ensure ignition switched OFF.<br />

Bridge black data link connector (DLC) terminal 1 [A] and<br />

brown or white data link connector (DLC) terminal 1 [B] with<br />

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

Operate switch and hold.<br />

Switch ignition ON.<br />

Release switch after 5 seconds.<br />

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

ECM fault memory.<br />

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

End of test sequence<br />

Method 2<br />

1111 ( Engine control module (ECM) I ECM<br />

Engine management<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 />

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

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

Idle speed control (ISC) actuator<br />

Crankshaft position (CKP) sensor<br />

I Closed throttle position (CTP) switch<br />

Probable cause<br />

-<br />

Wiring, multi-plug incorrectly wired, ISC actuator<br />

Insecure rotor, wiring, CKP sensor<br />

Accelerator cable adjustment, CTP switch<br />

adjustment, wiring, CTP switch<br />

221 2 I Throttle position (TP) sensor I Wiring, poor connection, TP sensor<br />

2234<br />

2312<br />

Engine control module (ECM) - supply voltage<br />

Engine coolant temperature (ECT) sensor<br />

Battery, wiring<br />

2322 I Intake air temperature (IAT) sensor I Wiring, IAT sensor<br />

Wiring, poor connection, ECT sensor<br />

2341 rn 1 Heated oxygen sensor (H02S) - lambda control Heating inoperative, exhaust leak, misfire, fuel<br />

pressurelpump, EVAP canister purge valve<br />

2342<br />

2413 fl<br />

4444<br />

Heated oxygen sensor (H02S)<br />

Mixture control (MC)<br />

No fault found<br />

Wiring, H02S, heating inoperative, fuel level low<br />

Fuel level low, fuel pressurelpump, intakelexhaust<br />

leak, misfire, HOZS, EVAP canister purge valve,<br />

injector, excessive fuel in engine oil<br />

rn <strong>Trouble</strong> code may be displayed if engine is not idling during self-diagnosis due to missing CKP sensor signal. Ignore trouble code if<br />

engine starts.<br />

After repairs, erase learnt lambda control values: Wait 30 seconds. Disconnect battery or ECM multi-plug for at least 30 seconds.<br />

Carry out road test to allow ECM to re-learn basic values.<br />
