Example: Main Line Between Data Link Connector and ABS Actuator and Electric Unit (Con-
trol Unit) Open Circuit
SKIB8740E
Unit name Symptom
ECM Engine torque limiting is affected, and shift harshness increases.
BCM

Reverse warning chime does not sound.

The front wiper moves under continuous operation mode even though the front
wiper switch being in the intermittent position.
EPS control unit The steering effort increases.
Combination meter

The shift position indicator and OD OFF indicator turn OFF.

The speedometer is inoperative.

The odo/trip meter stops.
ABS actuator and electric unit (control unit) Normal operation.
TCM No impact on operation.
IPDM E/RWhen the ignition switch is ON,

The headlamps (Lo) turn ON.

The cooling fan continues to rotate.
