WIRING DIAGRAM

10BP1: CHECK INPUT SIGNAL FOR ECM.
1. Turn ignition switch to ON.

Connector & Terminal (B135) No.16 (+) - Chassis Ground (-):

2. Measure voltage between ECM and chassis ground.

CHECK: Is the voltage more than 4.5 V?

YES: Go to step 10BP2.

NO: Go to step 10BP4.

10BP2: CHECK INPUT SIGNAL FOR ECM.

Connector & Terminal (B135) No.16 (+) - 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 10BP3.

10BP3: 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.

10BP4: CHECK HARNESS BETWEEN ECM AND TCM CONNECTOR.
1. Turn ignition switch to OFF.
2. Disconnect connectors from ECM and TCM.

Connector & Terminal (B135) No.16 - (B54) No.13:

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

CHECK: Is the resistance less than 1 ohm?

YES: Go to step 10BP5.

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

10BP5: CHECK HARNESS BETWEEN ECM AND TCM CONNECTOR.

Connector & Terminal (B135) No.16 - 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 10BP6.

10BP6: 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.
