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 the malfunction occurs only during high humidity or rainy/snowy weather, perform the following steps:
- Connect the M-MDS to the DLC-2 if you are inspecting sensors or switches.
- Turn the ignition switch to the ON position (Engine off.)NOTE:
- If the engine starts and runs, perform the following steps at idle.
- Access the PIDs for sensors or switches if you are 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 the part if necessary.
