Vibration inspection

If there is a malfunction while the vehicle vibrates such as while driving on a rough-road, perform the following procedure.

NOTE:

The following are possible causes for an electrical malfunction caused by vehicle vibration.

If the wiring harness is not routed correctly, it may be caught between some parts.
The main areas to be inspected include the connecting area of a connector, areas that vibrate, or areas where a wiring harness passes though the firewall or body panel.

Display the PIDs for the electrical system components (such as switches, sensors, actuators, and relays) suspected to be the malfunction cause. (See PID/DATA MONITOR INSPECTION ).
When inspecting a switch, turn the switch on manually.
CAUTION:
- Do not apply excessive force when shaking the part or wiring harness. Otherwise, an open circuit may occur.
Lightly shake connectors and wiring harnesses while verifying the PID value.

- If a PID value does not stabilize, inspect the connector and terminal for poor connection.
Lightly shake a part while verifying the PID value.

- If the PID value does not stabilize or a part mis-operation occurs, inspect the connector and terminal for a poor connection and the part for poor installation.
Operate the simulation function for the electric system component suspected to be the malfunction cause. (See SIMULATION INSPECTION ).
Lightly shake the part after operating the simulation function.

If abnormal noise occurs from the part, inspect the connector and terminal for poor connection and the part for poor installation.
