Can Bus Diagnostics Table

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

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 section for each system. Observe the diagnostic procedure below only when the CAN bus line is defective.
