Programming the Sun Roof Actuator

Each time the battery is disconnected, the sun roof actuator will need to be programmed. The sun roof actuator needs to be programmed for two different positions. First of all, the sun roof actuator needs to learn the end stop positions for being fully open and fully closed. Second, the sun roof actuator needs to learn the fully tilted position. The following steps explain how to program the sun roof actuator:
