Action for Non-repeatable Malfunction: Notes
- If the malfunction does not recur, perform the following inspection.
- Perform the DTC inspection and repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC INSPECTION .)
- Based on the repair order form, attempt to drive the vehicle or perform tests to determine the malfunction cause according to the data (such as module voltage) at that time.
- Perform vibration inspection. (See VIBRATION INSPECTION .)
- Inspect the female terminals on the connector of the electric component which is suspected to be the cause of the malfunction for poor connection. (See ELECTRICAL SYSTEM [(US)]
.)NOTE:
- Tool used (Reference): terminal test kit (49US-15-KIT)
- Verify if the malfunction symptom occurs during high engine load (switches such as headlights, A/C, wipers are on).
- If a commercially-available electrical device has been installed, verify if the malfunction symptom occurs while the device is removed.
- Warm the electric system components using a hair dryer and verify that the voltage (resistance) does not change.
- Perform water spraying inspection. (See WATER SPRAYING INSPECTION .)
