Calibrate 2nd Row Seat - Right Pitch

The second row pitch calibration sets the soft end stops for the seat's pitch hall sensor. In General Assembly, all seats should arrive pre-calibrated to end of line testing. This particular routine will first check for a valid calibration and pass if it is present. If it is not pre-calibrated, the seat will pitch backwards until the seat latches. Once the latch is detected, the seat will pitch forward until reaching a stall current at the latch, and then back off to a home position (zero position). If the seat does not latch within 2 seconds during the first step, or encounters an obstacle while approaching the home position, the routine will fail. If the seat is pitched too far forward at the start of the routine, the calibration will fail on the first attempt.

Calibrate 2nd Row Seat - Right Track

The second row track calibration sets the soft end stops for the track. There is a hall sensor mounted to the track, which in combination with a 100mm metal shunt in the rearward end of travel is used to determine whether the seat is in the comfort zone. When the calibration is run, if the seat is forward of the shunt (forward 220mm of travel), the seat will move rearward until the hall sensor reaches the edge of the shunt. If the seat is in the comfort zone, the seat will move forward until the hall sensor reaches the edge of the shunt. Make sure seat install mode is turned OFF before calibrating.
