DIAGNOSTICS PROCEDURE

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)". <Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) .>	Go to step 2 .
2 CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR . Turn the ignition switch to OFF. Remove the starter relay. Disconnect the connectors from ECM and starter motor. Measure the resistance of harness between ECM connector and starter relay connector. Connector & terminal CVT model (B134) No. 46 - (B159) No. 4: MT model (B134) No. 46 - (B158) No. 5: NOTE: For CVT model, place the select lever in "P" range or "N" range.	Is the resistance less than 1 Ω?	Go to step 3 .	NOTE: Check the following item and repair or replace if necessary. Open circuit of harness between ECM connector and starter relay connector Poor contact of coupling connector
3 CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR . Measure the resistance between ECM connector and chassis ground. Connector & terminal (B134) No. 46 - Chassis ground:	Is the resistance 1 MΩ or more?	Repair the poor contact of ECM connector.	Repair the short circuit to ground in harness between ECM connector and starter relay connector.
