ENGINE (DIAGNOSTICS)(H4DO) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)

DTC DETECTING CONDITION:

Detected when two consecutive driving cycles with fault occur.

TROUBLE SYMPTOM:

Failure of engine to start

CAUTION:

After repairing or replacing the defective part, perform the Clear Memory Mode and Inspection Mode .

WIRING DIAGRAM:

• LHD model

• RHD model

STEP	CHECK	YES	NO
1.CHECK FOR ANY OTHER DTC ON DISPLAY.	Is any other DTC displayed?	Check DTC using “List of Diagnostic Trouble Code (DTC)”.
2.CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR. 1) Turn the ignition switch to OFF. 2) Disconnect the connectors from ECM and starter relay. 3) Measure the resistance of harness between ECM and starter relay connector. NOTE: For AT model, place the select lever in “P” range or “N” range. Connector & terminal LHD model (B136) No. 34 — (B225) No. 10: RHD model (B136) No. 34 — (B225) No. 25:	Is the resistance less than 1 Ω?		Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit of harness between ECM and starter relay connector • Poor contact of joint connector (RHD model)
3.CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR. Measure the resistance between ECM and chassis ground. Connector & terminal (B136) No. 34 — Chassis ground:	Is the resistance 1 MΩ or more?	Repair the short circuit to ground in harness between ECM and starter relay connector.	Repair the poor contact of the ECM connector.
