Action For Non-repeatable Malfunction

• If the malfunction does not recur, verify the malfunction cause by performing the following actions:

• Verify that a DTC has been recorded in the memory. (See DTC INSPECTION .)
• Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.
• Refer to [Determining Open Circuit Location] based on the recorded DTC, shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for any changes in CAN system voltage or occurrence of any DTCs.
