Montero V6-3.8L SOHC (2005)
4. To observe the waveform with an oscilloscope: Start the engine, move the transfer selector lever to the "4H" position and the transmission selector
lever to "D" range, and then spin the wheel.
NOTE: The output waveform is low when the wheel speed is low. Similarly, it will be higher as the wheel speed increases. Waveform may also
be observed by driving the vehicle.
POINTS IN WAVEFORM MEASUREMENT
NOTE: The ABS sensor cable moves in relation to motion of the front or rear suspension. Therefore, it is likely that it has an open circuit only when
driving on rough roads but it functions normally when driving on smooth roads. It is recommended to observe sensor output voltage waveform also
under special conditions, such as driving on a rough road.
