Toyota Tacoma 2015-2018 Service Manual / Park Assist / Monitoring / Blind Spot Monitor System / Steering Angle Sensor (C1A47)

DESCRIPTION

The blind spot monitor sensor receives steering angle signals from the spiral cable with sensor sub-assembly via CAN communication.

DTC Code	DTC Detection Condition	Trouble Area
C1A47	A fail flag is transmitted from the steering sensor	Spiral cable with sensor sub-assembly Blind spot monitor sensor LH Blind spot monitor sensor RH

CAUTION / NOTICE / HINT

NOTICE:

When checking for DTCs, make sure that the blind spot monitor main switch assembly (warning canceling switch assembly) is on.

PROCEDURE

CHECK DTC

(a) Clear the DTCs (See page (b) Recheck for DTCs and check if the same DTC is output again. ).

(b) Recheck for DTCs and check if the same DTC is output again.

OK:

No DTCs are output.

USE SIMULATION METHOD TO CHECK
