NOTE: This DTC will only set during the cinching operation after the 4
second time out. This may make it difficult to reproduce.
With the DRBIII
t, record and erase DTC’s.
Turn the ignition off, wait 10 seconds, then turn the ignition on.
Operate the power sliding door several times if possible.
With the DRBIII
t, read ACTIVE DTCs.
Does the DRBIII
t display INCOMPLETE LATCH CINCH - NO PAWL TRANSI-
TION?
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
door several times and check for any binding or other obstruc-
tions.
Perform BODY VERIFICATION TEST - VER 1.
2
Examine the door for proper fit and alignment, loose/ hard or torn seals, worn teeth
on the rack and gear (lower drive unit) or anything that would cause an obstruction
to proper operation.
Manually operate the other sliding door or of a known good vehicle and notice the
effort needed to open and close.
Compare the effort needed on the disabled door.
Does it take more effort to operate the door than it should?
All
Yes
→ Refer to Service information for the related symptom(s).
