Go to Flag 1. Check the wire for a short circuit to GND.
Go to Flag 1 and Flag 2. Check the wires for an open circuit. If the wires are good, replace
the DADF Exit Sensor (PL 20.9). If the problem continues, replace the DADF Control
PWB (PL 20.3).
Enter dC330 [005-081] and press Start. DADF Exit Motor operates.

If a fuse is not available, replace the DADF Control PWB
VDC wires on the DADF Exit Motor for a short circuit to frame. If the problem contin-
ues, replace the DADF Exit Motor
+24 VDC is measured between P/J596-1 on the DADF Control PWB and GND.

Replace the DADF Control PWB
NOTE: In the following step, one of the pins to the motor ( P/J596-2, 3, 4, or 5) will mea-
sure approximately +2 to +5 VDC. This is normal operation.
+24 VDC is measured between P/J596-2, 3, 4, or 5 on the DADF Control PWB and
GND.
