- Refer to appropriate wiring diagram and verify whether or not there is a common connector between the following terminals:
- Brake switch terminal D-PCM terminal 2G
- Brake switch terminal C-PCM terminal 2R
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground.
- If the short to ground circuit could not be detected in the wiring harness:

- Is the voltage 0 V?
|
Yes |
Go to the next step. |
| No |
Refer to appropriate wiring diagram and verify whether or not there is a common connector between the following terminals:
