WIRING DIAGRAM

10BO1: 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 V?

YES: Go to step 10BO2.

NO: Go to step 10BO4.

10BO2: 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 V?

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

NO: Go to step 10BO3.

10BO3: 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.

10BO4: 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 10BO5.

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

10BO5: 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 10BO6.

10BO6: 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.
