(PWM) Pulse width modulation (%) (R) Rack position (mm) 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.
