nector M55 terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 4

NO

>> Repair or replace malfunctioning components.

4.

CHECK YAW RATE/SIDE/DECEL G SENSOR HARNESS

1. Check continuity between ABS actuator and electric unit (control

unit) connector E26 (A) terminals 14 and 25 and yaw rate/side/

decel G sensor harness connector M55 (B) terminals 2 and 3.

2. Check continuity between ABS actuator and electric unit (control

unit) connector E26 (A) terminals 14, 25 and ground.

Is the inspection result normal?

YES

>> GO TO 5

NO

>> Repair or replace malfunctioning components.

5.

CHECK DATA MONITOR
