TEST
ACTION
APPLICABILITY
1
With the DRBIII
t, record and erase DTC’s.
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 CINCH - OVERCURRENT?
All
Yes
→ 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
Yes
→ Refer to Service information for the related symptom(s).
Perform BODY VERIFICATION TEST - VER 1.
