Water spraying inspection

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

If the malfunction occurred during high humidity, heavy rain, or heavy snow conditions, perform the following procedure.
CAUTION:
- Spray water on the front of the radiator to change the temperature and humidity indirectly. If water leaks into the vehicle, it could damage a module. If there is the possibility of water leaking into the vehicle, carefully perform the inspection.

Display the PIDs for the electrical system components (such as switches, sensors, actuators, and relays) suspected to be the malfunction cause. (See PID/DATA MONITOR INSPECTION .)
When inspecting a switch, turn the switch on manually.
Spray water on the vehicle.
