Can Bus Diagnostics Table: Notes
WARNING: This page is about a different car, the 2004 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.
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 diagnosis procedure below only when the CAN bus line is defective.
CAUTION:
During diagnosis, a DTC code associated with another system may be set when the ignition switch is turned on with connector(s) disconnected. After completing the repair, confirm all systems for DTC code(s). If DTC code(s) are set, erase them all.
