DESCRIPTION

Refer to DTCs C1401 and C1402 (See page ).

DTC Code	DTC Detection Condition	Trouble Area
C1409 C1410	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.
