WIRING DIAGRAM

11CY1: CHECK INPUT SIGNAL FOR ECM.

1. Turn ignition switch to OFF.

Connector & Terminal - [(B136) No.9 (+) - Chassis Ground (-)]:

2. Measure voltage between ECM and chassis ground.

CHECK: Is the voltage more than 10 V?

YES: Repair poor contact in ECM connector.

NO: Go to step 11CY2.

11CY2: CHECK HARNESS BETWEEN ECM AND MAIN FUSE BOX CONNECTOR.

1. Disconnect connector from ECM.

Connector & Terminal - [(B136) No.9 (+) - Chassis Ground (-)]:

2. Measure resistance of harness between ECM and chassis ground.

CHECK: Is the resistance less than 10 Ohms?

YES: Repair ground short circuit in harness between ECM connector and battery terminal.

NO: Go to step 11CY3.

11CY3: CHECK FUSE SBF-5.

CHECK: Is fuse blown?

YES: Replace fuse.

NO: Repair harness and connector.

NOTE: In this case, repair the following:
- Open circuit in harness between ECM and battery
- Poor contact in ECM connector
- Poor contact in battery terminal
