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