Inspection Method for Switch Connectors or Wires

1. Connect the WDS or equivalent to the DLC-2.
2. Turn ignition switch to ON position (Engine OFF).
   NOTE:

   • If the engine starts and runs, perform the following steps at idle.
3. Access PIDs for the switch you are inspecting.
4. Turn switch on manually.
5. Shake each connector or wire harness a little vertically and horizontally while monitoring the PID.
   • If PID value is unstable, check for poor connection.
