POSSIBLE CAUSE

NOTE:

Confirm if DTC is PAST or CRNT. If DTC is CRNT, proceed with Diagnosis Procedure. If DTC is PAST, clear the DTC. Do not replace the ABS actuator and electric unit (control unit) for a PAST DTC.

PAST DTC	CRNT DTC
Harness or connector ABS actuator and electric unit (control unit) power supply system Fuse Fusible link Battery CAN communication line Incomplete neutral position adjustment of steering angle sensor Improper installation of steering angle sensor	Harness or connector Steering angle sensor ABS actuator and electric unit (control unit) Fuse block J/B CAN communication line Wheel alignment Incomplete neutral position adjustment of steering angle sensor ABS actuator and electric unit (control unit) power supply system Fuse Fusible link Battery
