Turn the ignition off, wait 10 seconds, then turn the ignition on.
Operate the power liftgate several times if possible.
With the DRBIII
t, read ACTIVE DTCs.
Does the DRBIII
t display INCOMPLETE LATCH RELEASE - NO REVERSE TO
UNLOAD CLUTCH?
All
Yes
→ Go To 2
No
→ Operate the liftgate several times and check for any binding or
other obstructions. To test the reverse action, open the liftgate
part way and continue holding the handle for 4 seconds. The
motor should run for approximately 2 seconds.
Perform BODY VERIFICATION TEST - VER 1.
2
Examine the liftgate for proper fit and alignment, torn seals or anything that would
cause an obstruction to proper operation.
Manually operate the liftgate of a known good vehicle and notice the effort needed to
open and close.
Compare the effort needed on the disabled liftgate.
Especially notice the effort needed to unlatch and latch the liftgate.
Does it take more effort to operate the liftgate than it should?
All
Yes
