Toyota Tacoma (2015-2018) Service Manual / Brake Control / Dynamic Control Systems / Vehicle Stability Control System(for Hydraulic Brake Booster) / Rear Speed Sensor RH Performance (C1411,C1412)

DESCRIPTION

Refer to DTCs C1401 and C1402 (See page ).

DTC Code	DTC Detection Condition	Trouble Area
C1411 C1412	One of the following conditions is met: When the vehicle is driven in reverse at a speed of 3 km/h (2 mph) or more and 3 of the wheel sensors detect the reverse signal, the other sensor detects a high frequency pulse 75 times while the ignition switch is ON. At a vehicle speed of 10 km/h (6 mph) or more, the vehicle speed sensor output drops by 50% for 5 seconds. The lowest wheel speed is 10 km/h (6 mph) or more and the difference between the highest and lowest wheel speed values is 2 km/h (1 mph) or less for 15 seconds. At a vehicle speed of 30 km/h (19 mph) or more, one wheel direction is different from the other 3 wheels for 1 second. At a vehicle speed of 100 km/h (62 mph), a reverse signal is output for 1 second or more. At a vehicle speed of 30 km/h (19 mph) or more, the rotation direction of one of the wheels is not detected normally and the rotation direction of the other 3 wheels is not the same for 1 second.
