Rack sensor output characteristics
1. Rack limit adjustment
(1)Measure the rack position R2 for PWM a2%.
(2)Confirm that it is within the range R2 = 15+-1 mm.
(3)Measure the rack position R1 at PWM a %.
(4)Confirm that it is within the range R2 - R1 = 10+-0.1 mm.
2. Check the limp home operation.
(1)Move the switch box's limp home switch to the limp home side.
(2)Confirm rack position L1 (mm ) and L2 (mm) for PWM in the above table.
3. Check the pull down operation.
(1)Confirm that the rack position is 19 mm at PWM B%.
(2)In the conditions described in the above table, move the switch box's pull down switch to the pull down side and confirm that the rack position momentarily becomes 1 mm or less.
