DESCRIPTION
Each speed sensor detects wheel speed and sends signals to the skid control ECU (brake actuator assembly). These signals are used by the ABS control.
HINT:
The output voltage values shown below are for when the vehicle wire harnesses are connected to the skid control ECU (brake actuator assembly) and the speed sensors.

Any of the following is detected:
-
The vehicle speed is more than 50.4 km/h (31 mph) and pulses are not detected for 0.4 seconds.
-
After the initial start or restart and when the vehicle speed has reached 12 km/h (7 mph), a wheel speed of 0 km/h (0 mph) is detected.
-
After the initial start or restart and when the vehicle speed has reached 20 km/h (12 mph), a front wheel speed of 0 km/h (0 mph) is detected.
-
The following conditions are met for 9 to 72 seconds or more (varies depending on the driving conditions):
-
The difference between the speed of the fastest wheel and the speed of the slowest wheel is 5% or more of the vehicle speed. (If the speed of any wheel is less than 5 km/h (3 mph), a speed difference of up to 15% is allowable.)

(a) Remove the front speed sensor rotor (front axle hub sub-assembly).
Click here
(b) Check the speed sensor rotor.
OK:
The rotor is free of scratches, oil, and foreign matter.
NOTICE:
-
If there is oil or foreign matter on the speed sensor rotor, clean the speed sensor rotor.
-
If the speed sensor rotor is damaged, replace the speed sensor rotor with a new one.
-
Check the speed sensor signal after cleaning or replacement.

HINT:
-
The front speed sensor rotor is incorporated into the front axle hub sub-assembly.
-
If the front speed sensor rotor needs to be replaced, replace it together with the front axle hub sub-assembly.

CHECK HARNESS AND CONNECTOR (BRAKE ACTUATOR ASSEMBLY - FRONT SPEED SENSOR)
|
(a) Turn the ignition switch off.
(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
OK:
The connector is securely connected.
(c) Disconnect the A33 skid control ECU (brake actuator assembly) connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the resistance according to the value(s) in the table below.
