| CHECK HARNESS BETWEEN GLOW RELAY CONNECTOR AND GLOW PLUG CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Remove the glow relay. 3) Disconnect the connectors from all glow plugs. 4) Measure the resistance of harness between glow relay connector and glow plug connector. Connector & terminal #1 (F9) No. 9 — (E121) No. 1: #2 (F9) No. 9 — (E128) No. 1: #3 (F9) No. 9 — (E120) No. 1: #4 (F9) No. 9 — (E129) No. 1: |
