9F-37 Security and Locks:
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at
the liftgate switch.
2. Ignition OFF, test for less than 1.0 ohm of resistance
between the ground circuit terminal C and ground.
➢ If greater than the specified range, test the ground
circuit for an open/high resistance.
3. Ignition ON, verify the scan tool Ext Trunk/Liftglass
Rel Sw parameter is Inactive.
➢ If not the specified value, test the signal circuit
terminal A for a short to ground. If the circuit tests
normal, replace the BCM.
4. Install a 3-A fused jumper wire between the signal
circuit terminal A and ground. Verify the scan tool Ext
Trunk/Liftglass Rel Sw parameter is Active.
➢ If not the specified value, test the signal circuit for a
short to voltage or an open/high resistance. If the
circuit tests normal, replace the BCM.
5. If all circuits test normal, test or replace the liftgate
switch.
Repair Instructions
Perform the "Diagnostic Repair Verification - Vehicle
Diagnostic Information: " after completing the diagnostic
procedure.
"Control Module References: " for BCM replacement,
setup, and programming

Symptoms - Vehicle Access

NOTE
1. Perform "Diagnostic System Check -
Vehicle Diagnostic Information: ", before
using the symptom tables in order to
verify that all of the following are true:
– There are no DTCs set.
– The body control module (BCM) can
communicate via the serial data link.
2. Review the system operation in order to
familiarize yourself with the system
functions. Refer to "Power Door Locks
Description and Operation".
Visual/Physical Inspection
Several of the symptom procedures ask for a careful
visual/physical check. This step is extremely important, it
could lead to correcting a problem without further checks
and can save valuable time. These checks include the
following:
• Inspect for aftermarket devices which could affect the
operation of the power door systems. Refer to
"Checking Aftermarket Accessories: ".
• Inspect the easily accessible or visible system
components and harness connectors for obvious
damage or conditions which could cause the
symptom.
Intermittents
NOTE
Check for proper installation of electrical
components if an intermittent condition
exists. Inspect for aftermarket theft deterrent
devices, lights and cellular phones. Ensure
that no aftermarket equipment is connected
to the class 2 circuit. If you can not locate an
intermittent condition, a cellular phone signal
may cause the condition. Faulty electrical
connections or wiring may also be the cause
of intermittent conditions. Refer to "Testing
for Intermittent Conditions and Poor
Connections: ".
NOTE
The problem may or may not turn on the
SERVICE VEHICLE SOON indicator or store a
DTC. Do not use the symptom tables to
diagnose intermittent conditions. The
malfunction must be present in order to
locate the problem.
Poor electrical connections or wiring cause most
intermittent conditions. Perform a careful visual/physical
check for the following conditions:
• Poor mating of the connector halves or a terminal not
fully seated in the connector body
• An improperly formed or damaged terminal
• Reform or replace connector terminals in the problem
circuit in order to insure proper contact tension.
• Poor terminal to wire connection requires removing
the terminal from the connector body in order to
perform the check.
Use a scan tool in order to help detect intermittent
conditions. The scan tool has several features that can
be used to locate an intermittent condition. The snapshot
feature can capture and store data parameters within the
scan tool when the malfunction occurs. This information
can then be reviewed in order to see what caused the
malfunction.
Symptom List
Refer to "Power Door Locks Inoperative" in order to
diagnose a symptom that does not set a DTC.
