Toyota Tacoma 2015-2018 Service Manual: Slave Module Horizontal Axis Misalignment (C1AC2)

Toyota Tacoma 2015-2018 Service Manual / Park Assist / Monitoring / Blind Spot Monitor System / Slave Module Horizontal Axis Misalignment (C1AC2)

DESCRIPTION

This DTC is stored when the angle of the blind spot monitor sensor RH deviates more than the allowable range from the horizontal axis.

HINT:

If drum tester such as a speedometer tester, brake/speedometer combination tester or chassis dynamometer is used with the blind spot monitor main switch assembly (warning canceling switch assembly) on, the blind spot monitor system may store this DTC by mistake.

DTC Code	DTC Detection Condition	Trouble Area
C1AC2	When the blind spot monitor sensor deviates 5 degrees or more from the horizontal axis when the system is activated.	Blind spot monitor sensor RH

CAUTION / NOTICE / HINT

NOTICE:

When checking for DTCs, make sure that the blind spot monitor main switch (warning canceling switch assembly) is on.
If the bumper is damaged or the vehicle has a history of body repair, there is a possibility that the installation area of the blind spot monitor sensor may be deformed and the blind spot monitor sensor system may not operate correctly, so visually inspect the blind spot monitor sensor installation area (frame, stud bolt) to make sure it is not dented or bent.

If the visual inspection finds a problem, check the installation condition of the blind spot monitor sensor, and adjust the installation position of the blind spot monitor sensor as necessary.

PROCEDURE

1.	CHECK INSTALLATION CONDITION

(a) Check the installation condition of the blind spot monitor sensor RH (See page HINT: HINT: ).

HINT:

Take the appropriate action in accordance with the result.

2.	PERFORM BEAM AXIS CONFIRMATION

(a) Install the rear bumper.
