| CHECK COMMUNICATION CIRCUIT HARNESS. |
|
1) Turn the ignition switch to ON. (engine OFF) 2) Measure the voltage between the body integrated unit harness connector terminal and chassis ground. Connector & terminal (B280) No. 4 (+) — Chassis ground (−): (B280) No. 15 (+) — Chassis ground (−): |
| QUESTION | |
|
Is the voltage 0 V? | |
| Yes | No |
|
|
Because the battery voltage or ignition switch “ON” circuit is shorted, repair the harness between the body integrated unit and ECM. |
