Symptom:
LIFTGATE POWER RELEASE OUTPUT OPEN - BCM
When Monitored and Set Condition:
LIFTGATE POWER RELEASE OUTPUT OPEN - BCM
When Monitored:
Continuously for non power liftgate vehicles
Set Condition:
When the Body Control Module senses there is no resistance on the
Liftgate Release Driver circuit after receiving a release command for longer than 125 ms,
it will not send any current out on that circuit and will set this DTC.
POSSIBLE CAUSES
DTC PRESENT
LIFTGATE RELEASE MOTOR OPEN
LIFTGATE RELEASE DRIVER WIRE OPEN

monitoring the DRBIII
t.
Does the DRBIII
t display LIFTGATE POWER RELEASE OUTPUT OPEN?
All
Yes
→ Go To 2
No
→ Using the wiring diagram/schematic as a guide, inspect the
wiring and connectors for an intermittent condition.
Perform BODY VERIFICATION TEST - VER 1.
2
Disconnect the Liftgate Ajar Switch (Power Release) connector.
Using a 12-volt test light, connect one end of the light to the Liftgate Release Driver
