ENGINE (DIAGNOSTICS)(H4DO) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)
DTC DETECTING CONDITION:
Immediately at fault recognition
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:
1.CHECK HARNESS BETWEEN STARTER RELAY (PUSH BUTTON START) CONNECTOR AND STARTER CUT RELAY CONNECTOR.
1) Turn the ignition to OFF.
2) Remove the starter relay (push button start) and starter cut relay.
3) Measure the resistance of harness between starter relay (push button start) connector and starter cut relay connector.
Connector & terminal
(B425) No. 25 — (B425) No. 1:
|
Is the resistance less than 1 Ω?
|
|
Repair the open circuit in harness between starter relay (push button start) connector and starter cut relay connector.
|
2.CHECK HARNESS BETWEEN ECM AND STARTER CUT RELAY CONNECTOR.
1) Disconnect the connectors from the ECM.
2) Measure the resistance of harness between ECM and starter cut relay connector.
Connector & terminal
(B135) No. 33 — (B425) No. 3:
|
Is the resistance less than 1 Ω?
|
|
Repair the open circuit of harness between ECM and starter cut relay connector.
|
3.CHECK STARTER CUT RELAY.
1) Connect the battery to starter cut relay terminals No. 1 and No. 3.
2) Measure the resistance between starter cut relay terminals.
|
Is the resistance 1 MΩ or more?
|
Repair the poor contact of the ECM connector.
|
Replace the starter cut relay.
