Inspection Method for Sensor Connectors or Wires

Connect the M-MDS to the DLC-2.
Switch the ignition ON (engine off).
NOTE:
- If the engine starts and runs, perform the following steps during idling.
Access the PIDs for the switch you are inspecting.
Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID.
- If the PID value is unstable, check for poor connection.
