TROUBLE DIAGNOSIS
Revision: June 20062007 Versa
Symptom When Error Occurs in CAN Communication SystemUKS005Y5
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
Unit name Symptom
ECM Engine torque limiting is affected, and shift harshness increases.
BCM Reverse warning chime does not sound.
EPS control unit Normal operation.
Combination meter

Shift position indicator and OD OFF indicator turn OFF.

Warning lamps turn ON.
ABS actuator and electric unit (control unit) Normal operation.
TCM No impact on operation.
IPDM E/R Normal operation.

4. Search for the possible cause using CAN communication signal chart using information from the interview
with the customer.
NOTE:
For the details of CAN communication signal, refer to LAN-48, "
CAN Communication Signal Chart" .
a. ABS warning lamp turned ON and speedometer did not move: This means that “ABS warning lamp signal”
and “Vehicle speed signal” could not communicate between M&A and ABS (4-a in the figure).
b. The tachometer moved normally: This means that “Engine speed signal” could communicate normally
between ECM and M&A (4-b in the figure).
