Inspection Method for Switch Connectors or Wires: Notes

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