Check Power Supply And Ground Circuit
CHECKING POWER SUPPLY AND GROUND CIRCUIT
| Step | Check | Yes | No |
|---|---|---|---|
1 : CHECK POWER SUPPLY.
Connector & terminal (B176) No. 14, No. 15 (+) - Chassis ground (-): |
Is the voltage more than 10 V? | Go to step 2. | Check the harness for open circuits and shorts between the keyless entry control unit and fuse. |
| 2 : CHECK GROUND CIRCUIT. Measure the resistance between the harness connector terminal and chassis ground. Connector & terminal (B176) No. 11 - Chassis ground: |
Is the resistance less than 10 ohm? | The power supply and ground circuit are OK. | Repair the harness. |
