|
Measure the resistance of harness between ECM connector and chassis ground. Connector & terminal (B137) No. 1 — Chassis ground: (B137) No. 2 — Chassis ground: (B137) No. 3 — Chassis ground: (B137) No. 7 — Chassis ground: (B134) No. 5 — Chassis ground: |
| QUESTION | |
|
Is the resistance less than 5 Ω? | |
| Yes | No |
|
|
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit of harness between ECM and engine ground cable • Poor contact in ECM connector • Poor contact of coupling connector |
