TROUBLE DIAGNOSIS
NOTE:
When data link connector branch line is open, transmiss ion and reception of CAN communication signals are
not affected. Therefore, no symptoms occur. However, be sure to repair malfunctioning circuit.
Example: CAN-H, CAN-L Harness Short Circuit
CAN Diagnosis with CONSULTINFOID:0000000009461398
CAN diagnosis on CONSULT extracts the root c ause by receiving the following information.
Unit name Major symptom
ECM
Normal operation.
BCM
EPS control unit
Combination meter
ABS actuator and electric unit (control unit)
TCM
IPDM E/R
JSMIA0445GB
Unit name Major symptom
ECM • Engine torque limiting is affected, and shift harshness increases.
• Engine speed drops.
BCM • Reverse warning buzzer does not sound.
• The front wiper moves under continuous operation mode even though the front wiper switch being in the intermittent position.
• The room lamp does not turn ON.
• The engine does not start (if an error or malfunction occurs while turning the igni- tion switch OFF.)
• The steering lock does not release (if an error or malfunction occurs while turning the ignition switch OFF.)
EPS control unit The steeri ng effort increases.
Combination meter • The tachometer and the speedometer do not move.
• Warning lamps turn ON.
• Indicator lamps do not turn ON.
ABS actuator and electric unit (control unit) Normal operation.
TCM No impact on operation.
IPDM E/R When the ignition switch is ON,
• The headlamps (Lo) turn ON.
• The cooling fan continues to rotate.
