10. RECHECK DTC
HINT
*
Sometimes CAN communication system DTCs are output, but all ECUs and sensors connected to the CAN communication system
are displayed on the Techstream. In this case, previous or history DTCs may indicate the cause of the problem.
*
ECUs related to a problem in the CAN bus will store DTCs to indicate communication malfunctions. Communication stop mode in
the CAN bus can be determined by comparing the combination of DTCs that have been set. Refer to DTC Combination Table for
the CAN bus.
*
The power management control ECU will store communication error DTCs when the ECUs connected to the CAN No. 2 bus and
power management bus cannot communicate, or if a network malfunction occurs.
