WIRING DIAGRAM

1OBQ1: CHECK INPUT SIGNAL FOR ECM.
1. Turn ignition switch to ON.

Connector & terminal (B135) No.17 (+) - Chassis ground (-):

2. Measure voltage between ECM and chassis ground.

CHECK: Is the voltage more than 4.5 Volt?

YES: Go to step 10BQ2.

NO: Go to step 10BQ4.

10BQ2: CHECK INPUT SIGNAL FOR ECM.

Connector & terminal (B135) No.17 (+) - Chassis ground (-):

Measure voltage between ECM and chassis ground.

CHECK: Is the voltage more than 10 Volt?

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

NO: Go to step 10B03.

10BQ3: CHECK POOR CONTACT.
Check poor contact in ECM connector.

CHECK: Is there poor contact in ECM connector?

YES: Repair poor contact in ECM connector.

NO: Replace ECM.

10BQ4: CHECK HARNESS BETWEEN ECM AND TCM CONNECTOR.
1. Turn ignition switch to OFF.
2. Disconnect connectors from ECM and TCM.

Connector & terminal (B135) No.17 - (B54) No.21:

3. Measure resistance of harness between ECM and TCM connector.

CHECK: Is the resistance less than 1 ohm?

YES: Go to step 10BQ5.

NO: Repair open circuit in harness between ECM and TCM connector.

10BQ5: CHECK HARNESS BETWEEN ECM AND TCM CONNECTOR.

Connector & terminal (B135) No.17 - Chassis ground:

Measure resistance of harness between ECM and chassis ground.

CHECK: Is the resistance less than 10 ohm?

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

NO: Go to step 10BQ6.

10BQ6: CHECK POOR CONTACT.
Check poor contact in TCM connector.

CHECK: Is there poor contact in TCM connector?

YES: Repair poor contact in TCM connector.

NO: Replace TCM.
