Toyota Corolla Cross: Rear Side Radar Sensor (Module "A") Beam Axis Misalignment (Horizontal) (C1AC200)
DESCRIPTION
This DTC is stored when the angle of the blind spot monitor sensor RH (A) deviates more than the allowable range from the horizontal axis.
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.
