Water Sprinkling Method

CAUTION:

Indirectly change the temperature and humidity by spraying water onto the front of the radiator.
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.

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

Connect M-MDS to the DLC-2 if inspecting sensors or switches.
Switch the ignition to ON (engine off).
NOTE:
- If the engine starts and runs, perform the following steps during idle.
Access the PIDs for sensor or switch if inspecting sensors or switches.
If you are inspecting the switch, turn it on manually.
Spray water onto the vehicle or run it through a car wash.
- If the PID value is unstable or malfunction occurs, repair or replace part.
