Water Sprinkling Method
If malfunction occurs only under high humidity or rainy/snowy weather, perform the following steps:
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.
- Connect the M-MDS to the DLC-2 if you are inspecting sensors or switches.
- Switch the ignition to ON (engine off).NOTE:
- If the engine starts and runs, perform the following steps at idle.
- Access PIDs for sensor or switch 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 PID value is unstable or malfunction occurs, repair or replace part if necessary.
