PRECAUTION 1. IGNITION SWITCH EXPRESSIONS (a) The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section. Expression Ignition Switch (Position) Engine ...

Low Output Signal of Front Speed Sensor RH (Test Mode DTC) (C1271,C1272,C1401,C1402)
DESCRIPTION The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU (master cylinder solenoid). These signals are used for brake control. The speed sensor rotors have rows of alternating N and S magnetic poles and their magnetic fields change when t ...

Diameter of the Tire is not Uniform (C1337)
DESCRIPTION The skid control ECU (brake actuator assembly) measures the speed of each wheel by receiving signals from the speed sensors. These signals are used for recognizing whether all 4 wheels are operating properly. Therefore, all wheel signals must indicate the same speed. D ...
