Check the appropriate DTC using the “List of Diagnostic Trouble Code (DTC)”. List of Diagnostic Trouble Code (DTC)">

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0617 STARTER RELAY "A" CIRCUIT HIGH">Go to Step 2.

2.CHECK HARNESS BETWEEN ECM AND STARTER RELAY 1 CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connector from ECM.

3) Turn the ignition switch to ON.

4) Measure the voltage between ECM connector and chassis ground.

Connector & terminal

(B136) No. 16 (+) — Chassis ground (−):

NOTE:

For CVT model, place the select lever in “P” range or “N” range.

Is the voltage 10 V or more?

Repair the short circuit to power in harness between ECM connector and starter relay 1 connector.

Repair the poor contact of ECM connector.

1. OUTLINE OF DIAGNOSIS

Detect abnormal continuity in the starter SW.

Judge as ON NG when the starter SW signal remains ON.

2. EXECUTION CONDITION
