Water spraying inspection
- 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.
- If the PID value does not stabilize or there is a malfunction, inspect the applicable part.
