| CHECK HARNESS BETWEEN ECM AND FUEL INJECTOR CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connectors from ECM and all fuel injectors. 3) Measure the resistance of harness between ECM connector and fuel injector connector. Connector & terminal #1 (B135) No. 73 — (E5) No. 1: #1 (B135) No. 74 — (E5) No. 2: #2 (B135) No. 49 — (E16) No. 1: #2 (B135) No. 51 — (E16) No. 2: #3 (B135) No. 25 — (E6) No. 1: #3 (B135) No. 26 — (E6) No. 2: #4 (B135) No. 1 — (E17) No. 1: #4 (B135) No. 3 — (E17) No. 2: |
