Can Bus Diagnostics Table

WARNING: This page is about a different variant/trim than selected.

CAUTION: A diagnostic trouble code may not also be stored in the CAN-B lines under the conditions below. If no diagnostic trouble code has been stored due to electrical noise, confirm diagnosis item 26. (Refer to DIAGNOSTIC ITEM 26: SHORT TO POWER SUPPLY OR GROUND, OPEN CIRCUIT OR LINE-TO-LINE SHORT IN THE CAN-B BUS LINES .)

Open circuit at the CAN_H side of the CAN-B bus lines
Open circuit at the CAN_L side of the CAN-B bus line
Short to ground at the CAN_H side of the CAN-B bus line

CAUTION: During diagnosis, a diagnostic trouble code associated with another system may be stored when the ignition switch is turned on with connectors) disconnected. After completing the repair, confirm all systems for diagnostic trouble code(s). If diagnostic trouble code(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 diagnosis procedure below only when the CAN bus line is defective.
