Toyota CH-R Service Manual: Slave Module Horizontal Axis Misalignment (C1AC2)

HINT:

• If a drum tester such as a speedometer tester, brake/speedometer combination tester or chassis dynamometer is used with the blind spot monitor system on, the blind spot monitor sensor may store this DTC by mistake.
• When mud, snow, ice, a sticker, etc. is covering the sensor or its surrounding area on the rear bumper, the blind spot monitor sensor may store this DTC by mistake.

NOTICE:

• When checking for DTCs, make sure that the blind spot monitor system is turned 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.
