Inspection method for switch connectors or wiring harnesses

1. Connect the M-MDS to the DLC-2.
2. Switch the ignition to ON (engine off).
   NOTE:

   • If the engine starts and runs, perform the following steps during idle.
3. Access PIDs for the switch you are inspecting.
4. Turn the switch on manually.
5. Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID.

• If PID value is unstable, inspect for poor connection.
