Ye s®Go To 2
No®Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors for an intermittent condition. Operate the
liftgate several times and check for any binding or other obstruc-
tions.
Perform BODY VERIFICATION TEST - VER 1.
2 Examine the liftgate for proper alignment, worn or binding hinges, weak liftgate prop
assembly, loose/ hard weatherstrip, and gear teeth on the Power Liftgate Motor
assembly for wear or anything that would cause an obstruction to proper operation.
If necessary manually operate the power liftgate on a known good vehicle and notice
the effort needed to open and close for comparison.
Especially notice the effort needed to unlatch and close the liftgate.
Were there any mechanical problems found?All
Ye s®Refer to Service information for the related symptom(s).

3 With the DRBIIItin Inputs/Outputs, read the PAWL, RATCHET and FULL OPEN
switch state.
While observing the FULL OPEN switch state, manually lower the liftgate from full
open to part open. The switch should toggle from CLOSED to OPEN.
Open the Liftgate to full open position. While observing the PAWL switch state, click
the latch with a screwdriver to the first detent. The PAWL should toggle from
CLOSED to OPEN.
Open the Liftgate to the full open position. While observing the RATCHET switch
state, click the latch with a screwdriver to the second detent. The RATCHET should
toggle from CLOSED to OPEN.
Repeat the above steps several times.
