DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK FUSE.
|
Is the fuse blown out? | Replace the fuse. If the replaced fuse has blown out easily, repair the short circuit of harness of each fuse. | Go to step 2. |
| 2 CHECK INPUT VOLTAGE FOR PVIGN RELAY. Measure the voltage between PVIGN relay and chassis ground. Connector & terminal (B357) No. 2 (+) - Chassis ground (-): (B357) No. 3 (+) - Chassis ground (-): |
Is the voltage 10 - 13 V? | Go to step 3. | Repair the open circuit of harness between fuse (No. 12) and PVIGN relay. |
| 3 CHECK HARNESS BETWEEN PVIGN RELAY OF TCM. Measure the resistance between TCM connector and PVIGN relay connector. Connector & terminal (B54) No. 10 - (B357) No. 1: (B54) No. 7 - (B357) No. 4: (B54) No. 8 - (B357) No. 4: |
Is the resistance less than 1 Ω? | Go to step 4. | Repair the open circuit of harness. |
4 CHECK PVIGN POWER SUPPLY CIRCUIT.
|
Is the voltage 10 - 13 V? | Temporary poor contact. Recheck the harness between TCM and relay. (Lightly move the harness and check that the open or short circuit is not occurred.) | Go to step 5. |
| 5 CHECK PVIGN RELAY OUTPUT OF TCM. Measure the voltage between TCM connector and chassis ground. Connector & terminal (B55) No. 11 (+) - Chassis ground (-): |
Is the voltage less than 1.5 V? | Replace the PVIGN relay. | Replace the TCM. < Ref. to TRANSMISSION CONTROL MODULE (TCM) . > |
