Inspection Method For Switch And/Or Sensor Connectors Or Wires

Connect the M-MDS (IDS) to the DLC-2.
Switch the ignition to ON (engine off).
NOTE:
- If the engine starts and runs, perform the following steps at idle.
Access PIDs for the switch or sensor you are inspecting.
Turn the switch on manually.
Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID.
