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:

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.
