| CHECK HARNESS BETWEEN ECM AND IGNITION COIL AND IGNITOR ASSEMBLY CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connectors from the ECM. 3) Disconnect the connector from the ignition coil & ignitor assembly. 4) Measure the resistance of harness between ECM and ignition coil and ignitor assembly connector. Connector & terminal (B137) No. 21 — (E34) No. 1: (B137) No. 20 — (E33) No. 1: (B137) No. 19 — (E32) No. 1: (B137) No. 18 — (E31) No. 1: |
