Inspection Method For Sensor Connectors Or Wires

Connect the M-MDS 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 you are inspecting.
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
