Sunroof Motor

The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the vent position to the open position, the following occurs:

• Voltage is supplied to the sunroof motor open control/output 1 circuit.
• Ground is maintained to the sunroof motor close control/output 2 circuit.

When the motor drives the sunroof in the direction from the open position to the vent position, the following occurs:

• Voltage is supplied to the sunroof motor close control/output 2 circuit.
• Ground is maintained to the sunroof motor open control/output 1 circuit.

The sunroof module is equipped with a timer circuit which stops the operation of the sunroof motor after 15 seconds.

The sunroof glass will hard stop each time the sunroof glass reaches the following:

• Full vent
• Closed
• Full open

The hard stop will cause an over current condition that the sunroof module monitors. As an over current condition or hard stop is detected, the sunroof module will stop any motor control outputs.
