| CHECK HARNESS BETWEEN ECM CONNECTOR 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 and ignitor assembly. 4) Measure the resistance of harness between ECM connector and ignition coil and ignitor assembly connector. Connector & terminal (B137) No. 18 — (E12) No. 1: (B137) No. 19 — (E12) No. 4: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
