Speed of the slowest wheel is less than 1/7th of the nd slowest wheel for at least 15 sec. when vehicle speed is 6 mph (10 km/h) or more. Abnormal high wheel speed pulse is input for at least 15 sec. Abnormal high wheel speed pulse is input at least 7 times when ECU is on. Speed sensor pulse signal is instantly cut 7 times or more. Speed sensor signal line is open for at least 0.5 sec. Right rear and left rear speed sensor Each speed sensor circuit Sensor rotor Sensor installation Skid control ECU TC C010/33 is for the right rear speed sensor. TC C015/34 is for the left rear speed sensor. The RAKE warning light comes on when speed sensor malfunctions are detected in two or more wheels.

2 IAGNOSTICS ELECTRONICALLY CONTOROLLE RAKE SYSTEM INSPECTION PROCEURE 1 CHECK HARNESS AN CONNECTOR(MOMENTARY INTERRUPTION) Using the handheld tester, check for any momentary interruption in the wire harness and connector corresponding to a TC (see page 05956). SP SEN RR SP SEN RL Item Measurement Item / Range (isplay) RR speed sensor open detection / OPEN or NORMAL RL speed sensor open detection / OPEN or NORMAL : There are no momentary interruption. Perform the above inspection before removing the sensor and connector. NG Go to step 5 Normal Condition NORMAL : Normal condition NORMAL : Normal condition REA VALUE OF HANHEL TESTER(REAR SPEE SENSOR) Connect the handheld tester to the LC3. (b) Start the engine. (c) Select the ATA LIST mode on the handheld tester.

(b) rive the vehicle at approximately 19 mph (30 km/h), and check the signal waveform. : A waveform as shown in a figure should be output. As the vehicle speed (wheel revolution speed) increases, a cycle of the waveform narrows and the fluctuation in the output voltage becomes greater. hen noise is identified in the waveform on the oscilloscope, error signals are generated due to the speed sensor rotor s scratches, looseness or foreign matter attached to it.
