Symptom When Error Occurs in CAN Communication SystemNKS004PF
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 LAN-41, "Abbreviation List" for the unit abbreviation.
Example: TCM branch line open circuit
SKIB8738E
