Vibration method
- If malfunction occurs or becomes worse while driving on a rough road or when engine is vibrating, perform the steps below.
Note. There are several reasons why vehicle or engine vibration could cause an electrical malfunction. Some of the things to check for are: Connectors not fully seated Wire harnesses not having full play Wires laying across brackets or moving parts Wires routed too close to hot parts An improperly routed, improperly clamped, or loose harness can cause wiring to become pinched between parts. The connector joints, points of vibration, and places where wire harnesses pass through the firewall, body panels, etc. are the major areas to be checked.

- Connect the M-MDS (IDS) to DLC-2.
- Switch the ignition to ON (engine off). NOTE: If engine starts and runs, perform the following steps at idle.
- Access the PIDs for the switch and/or sensor you are inspecting.
- Turn the switch on manually.
- Shake each connector or wire harness a bit vertically and horizontally while monitoring the PID. If the PID value is unstable, check for poor connection.
