Code B2594 Lincoln Description

The Power Sliding Door (PSD) Module supplies 12 volts to the latch actuator on a circuit through the sliding door contacts which release the power sliding door latch. Also, a 5-volt reference is supplied to the position sensor on circuit. The PSD detent switch circuit is monitored for a momentary ground signaling the rear latch is released. This circuit is monitored through the sliding door contacts and will open when the contacts separate. When the momentary PSD detent switch ground is detected by the PSD module, power is supplied to the drive assembly actuator clutch and motor which opens the power sliding door. As the power sliding door is opened, the position sensor is used to track the power sliding door movement and position. If there is no movement detected by the PSD module after an unlatch occurred, DTC B2594 sets.
