Water Sprinkling Method

If a malfunction occurs only during high humidity or rainy/snowy weather, perform the following steps:

• If a vehicle is subject to water leakage, the leakage may damage the control module. When testing a vehicle with a water leakage problem, special caution must be used.

1. Connect the M-MDS to the DLC-2 if you are inspecting sensors or switches.
2. Switch the ignition ON (engine off).
   NOTE:

   • If the engine starts and runs, perform the following steps at idle.
3. Access the PIDs for the sensor or the switch if you are inspecting sensors or switches.
4. If you are inspecting the switch, turn it on manually.
5. Spray water onto the vehicle or run it through a car wash.
   • If the PID value is unstable or a malfunction occurs, repair or replace parts if necessary.
