DTC Inspection Priority: Notes
If multiple DTCs are displayed at the same time, perform inspections one by one based on the following priority table. See DTC INSPECTION PRIORITY table. If DTC U1000 and/or U1001 are displayed with other DTCs, first perform diagnosis for U1000 or U1001. See DTC U1000: CAN COMMUNICATION LINE & DTC U1001: CAN COMMUNICATION LINE .
