Can Bus Diagnostics Table
CAUTION:
During diagnosis, a DTC associated with another system may be stored when the ignition switch is turned on with connector(s) disconnected. After completing the repair, confirm all systems for DTC(s). If DTC(s) are stored, erase them all.
This diagnosis applies only to the CAN bus lines. If a different system is defective, proceed to the applicable diagnosis information for each system. Observe the diagnostic procedure below only when the CAN bus line is defective.
