Vibration inspection
WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
- Connector connection malfunction
- There is no play in the wiring harness.
- The wiring harness contacts a moving part.
- The wiring harness is close to a high-temperature part.
- 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.
