NG -- REPAIR OR REPLACE SKID CONTROL SENSOR WIRE

OK -- Continue to next step.

10. INSPECT SPEED SENSOR AND SENSOR ROTOR SERRATIONS

(a) INSPECTION USING OSCILLOSCOPE

(1) Disconnect the rear speed sensor connector.

(2) Connect the oscilloscope to terminals 1 and 2 of the rear speed sensor.

(3) Check that a waveform is output when the tires are rotated.

OK:

A waveforms as shown in the figure should be output.

HINT

* As vehicle speed (wheel rotation speed) increases, the width of the waveform narrows and the fluctuation in the output voltage

becomes greater.

* When noise is identified in the waveform on the oscilloscope, error signals are generated due to rotor scratches, looseness or

foreign matter attached to the speed sensor.

NG -- CLEAN OR REPLACE SPEED SENSOR AND SENSOR ROTOR

OK -- Continue to next step.

11. READ VALUE USING TECHSTREAM (REAR SPEED SENSOR)

(a) Connect the Techstream to the DLC3.

(b) Start the engine.

(c) Select the Data List mode on the Techstream.
