Rodeo S 2WD L4-2.2L (1999)
G Sensor, ABS: Description and Operation
The G-sensor installed inside the EHCU detects the vehicle deceleration speed and sends a signal to the EHCU. In 4WD operation, all four wheels
may be decelerated in almost the same phase, since all wheels are connected mechanically.
This tendency is noticeable particularly on roads with low friction coefficient, and the ABS control is adversely affected.
The G-sensor judges whether the friction coefficient of road surface is low or high, and changes the EHCU's operating system to ensure ABS control.
