CAN COMMUNICATION SYSTEM ERROR
-
CAN communication line open (CAN-H, CAN-L, or both)
-
CAN communication line short (ground, between CAN communication lines, other harnesses)
-
Error of CAN communication control circuit of the unit connected to CAN communication line
WHEN "U1000" OR "U1001" IS INDICATED EVEN THOUGH CAN COMMUNICATION SYSTEM IS NORMAL
-
Removal/installation of parts: Error may be detected when removing and installing CAN communication unit and related parts while turning the
ignition switch ON. (A DTC except for CAN communication may be detected.)
-
Fuse blown out (removed): CAN communication of the unit may cease.
-
Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition switch ON (Depending on the control
unit which carries out CAN communication).
-
Error may be detected if the power supply circuit of the control unit, which carries out CAN communication, malfunctions (Depending on the
control unit which carries out CAN communication).
-
Error may be detected if reprogramming is not completed normally.
NOTE: CAN communication system is normal if "U1000" or "U1001" is indicated on DTC check of SDT under the above conditions. Erase the
memory of each unit.
LAN System: Symptom When Error Occurs in CAN Communication System
LAN System: Symptom When Error Occurs in CAN Communication System
In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmit and receive signals if any error occurs on
CAN communication line. Under this condition, multiple control units related to the root cause malfunction or go into fail-safe mode.
ERROR EXAMPLE
NOTE:
-
Each vehicle differs in symptom of each unit under fail-safe mode and CAN communication line wiring.
-
Refer to [How to Use This Section] for the unit abbreviation.
Example: TCM branch line open circuit
