Can Bus Diagnostics Table
WARNING: This page is about a different variant/trim than selected.
CAUTION:
A diagnosis code may not also be set in the CAN-B lines under the conditions below. If no diagnosis code has been set due to electrical noise, confirm diagnosis item 28 DIAGNOSTIC ITEM 28: DIAGNOSE THE ETACS-ECU, JOINT CONNECTOR (CAN1) OR LINES BETWEEN ETACS-ECU AND JOINT CONNECTOR (CAN1).
.
- 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 diagnosis 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 diagnosis code(s). If diagnosis code(s) are set, 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 diagnosis procedure below only when the CAN bus line is defective.
