Roof limits:

NOTE:
  • Motor Thermal Protection:  The ECU Calculates the internal motor temperature. When the calculated temperature exceeds 365F(185C), the ECU allows the roof to only close. At 392F(200C) The ECU prevents motor movement.
  • System Low Temperature Operation:  (Via the Vehicle Ambient Temp Sensor) At 14F (-10C) the ECU does not allow the system to vent without stopping the other motor. At -4F (-20C) the motors are allowed to close only.
  • Speed Thresholds:  At 86 m.p.h. (138 km/h) we stop operation and at 81 m.p.h. (129 km/h) we resume operation.
