(a) VIBRATION METHOD: When a malfunction seems to occur as a result of vibration.
(1) PART AND SENSOR
Apply slight vibration with a finger to the part of the sensor suspected to be the cause of the problem, and check whether the malfunction
occurs.
NOTICE: Applying strong vibration to relays may open relays.
(2) CONNECTORS
Slightly shake the connector vertically and horizontally.
(3) WIRE HARNESS
Slightly shake the wire harness vertically and horizontally.
HINT: The connector joint and fulcrum of the vibration are the major areas that should be checked thoroughly.
(b) HEAT METHOD: When a malfunction seems to occur when the area in question is heated.
(1) Heat the component that is the possible cause of the malfunction with a hair dryer or similar device. Check if the malfunction occurs.
NOTICE:
-
Do not heat to more than 60°C (140°F). Exceeding this temperature may damage the components.
-
Do not apply heat directly to the parts in the ECU.
(c) WATER SPRINKLING METHOD: When a malfunction seems to occur on a rainy day or in high-humidity.
(1) Sprinkle water onto the vehicle and check if the malfunction occurs.
NOTICE:
-
Never sprinkle water directly into the engine compartment. Indirectly change the temperature and humidity by spraying water onto the
front of the radiator.
-
Never apply water directly onto the electronic components.
HINT: If the vehicle has or had a water leakage problem, the leakage may have damaged the ECU or connections. Look for evidence of
corrosion or short circuits. Proceed with caution during water tests.
