(b) Start the engine.
(c) Drive the vehicle at a speed of 40 km/h (25 mph) or more for at least 60 seconds.
(d) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and

NOTICE:
Check the speed sensor signal after replacement See: Brakes and Traction Control/Antilock Brakes / Traction Control
Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Test Mode Procedure.
HINT
- If the front speed sensor rotor needs to be replaced, replace it together with the front drive outboard joint shaft assembly.
- If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1401,C1402: Front Speed
Sensor RH Malfunction
DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for ABS control.
Speed sensor rotors have 48 serrations The hall IC type speed sensor uses the frequency of output pulses to detect the vehicle speed. Because the
sensor outputs digital pulses, it can detect vehicle speeds even when the vehicle is nearly stationary.
HINT
- DTC C1401 is for the front speed sensor RH.
- DTC C1402 is for the front speed sensor LH.
