Description & Operation
Vehicles are equipped with power tilt and telescoping steering columns. Adjustment is made by moving tilt and power telescopic manual switch located on left side of steering column. Selected movement signal is sent to tilt and power telescopic Electronic Control Unit (ECU). Tilt and power telescopic ECU sends signal to either tilt or telescopic motors to adjust to selected position.
Power tilt steering column also contains an automatic feature for easier vehicle exits. When key is removed from ignition, tilt and power telescopic ECU will adjust column tilt fully upward and telescope fully retracted. When key is installed in ignition, steering column will return to previous tilt and power telescopic settings.
Vehicles are equipped with a 2-position, power tilt and power telescopic steering column memory feature. Position memory and return switches are located on driver's door. Once steering column is adjusted to desired setting, memory position can be set to return steering column to previously adjusted settings. Power tilt and power telescopic steering column memory position settings work in conjunction with power seat settings.
The power tilt steering column system consists of a key unlock warning switch, an auto set switch, a manual switch, driving position memory and return switch, telescopic motor, telescopic position sensor, tilt motor, tilt position sensor and a tilt and power telescopic ECU. See Fig 1 and Fig 2 .
