― Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data (such as keyless control module circuit voltage for advanced keyless entry and push button start system) (such as instrument cluster circuit voltage for keyless entry system) at that time, and detect the malfunction cause.
― Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for malfunction or occurrence of any DTCs.
