4. Outside temperature too high, above 143°F
(62°C) or too low, below -12°F (-24°C).
5. O/H console lockout will inhibit the B pillar
switches only.
6. Liftgate locked will inhibit all interior switches
from opening (overhead console). A locked lift-
gate can be power closed.
7. Pinch Sensor switch stuck shall inhibit the
power close feature.

POWER SLIDING DOOR SYSTEM
3.20.1
POWER SLIDING DOOR
The Power Sliding Door (PSD) system is acti-
vated through the use of the following: Remote
Keyless Entry (RKE), overhead console switches, B
pillar switches or the DRBIII
t. These inputs are
hardwired to the body control module (BCM) and
can be monitored with a diagnostic tool. The BCM
will send the message via PCI bus to the power
sliding door module (PSDM). The sliding door must
be in the full open or full closed position to operate.
Once the BCM sends a button activation message to
the PSDM, the module shall read all inputs, out-
puts and vehicle conditions to determine whether it
shall open, close or inhibit the PSD operation.
During an opening or closing cycle, the PSDM can
detect an obstacle present should it meet sufficient
resistance by the hall effect sensors (integrated in
the drive motor).
During an open cycle, multiple door activations
(RKE, overhead console, B pillar) are ignored until
the door reaches the full open position. However,
during a close cycle, a 2nd door activation (RKE,
overhead console, B pillar) will reverse the door to
the full open position.
If the engine is cranked during a power open/close
the PSD will pause then resume after engine crank-
ing. In addition, if the vehicle is placed in gear
during an open cycle, the PSD shall reverse direc-
tion and begin closing. If the vehicle is placed in
gear during a closing cycle, the PSD shall continue
closing until fully closed.
If the inside or outside handle is activated during
an open or close cycle, the PSD will become a full
manual sliding door. The child lockout is mechani-
cal only and has no effect on the B-pillar switch as
it did in previous models.
There is only one part number for the power
sliding door module (PSDM). The driver sliding
door harness has an additional ground circuit which
will identify it as the driver side. This eliminates
the need for a left and a right side module.
3.20.2
DIAGNOSTIC FEATURES
The PSDM can be flashed on vehicle via PCI bus
with a DRBIII
t diagnostic tool. The DRBIIIt can
read all inputs, actuate all outputs, read module
information, and read diagnostic trouble codes. As a
reminder, some DTC’s can be set during normal
PSD operation.
3.20.3
SYSTEM INHIBITORS
1. Battery voltage too high or too low (above 16V,
below 9.5V)
2. Vehicle in gear
3. Vehicle speed > 0 mph/km/h
4. O/H console lockout will inhibit the B pillar
switches
5. Doors locked will inhibit all interior switches
from opening (Overhead Console, B Pillar). A
locked sliding door can be power closed.

REAR WINDOW DEFOG/HEATED
MIRROR
The defroster button located on the HVAC control
controls the rear window defogger and the heated
side view mirrors.
When the defroster button is pushed, the HVAC
control sends a bus message over the PCI bus to the
Front Control Module (FCM) which controls the
Rear Window Defogger relay. The defroster LED
will illuminate when the defroster function is on.
The defroster will function for 10 minutes or can be
cycled off sooner by pressing the defroster button
again.

TELECOMMUNICATIONS
3.22.1
HANDS FREE PHONE
OVERVIEW
The vehicle telecommunications system consists
of a Hands Free Module, Rear View Mirror, and a
Blue-tooth Hands Free Profile enabled cell phone.
The system allows vehicle occupants to use voice
recognition technology to make, receive and screen
phone calls without physically handling a cell
phone. The system has a programmable phone book
that can prevent the vehicle operator from becom-
ing distracted searching for a specific number.
Seven different wireless phones can be pro-
grammed to operate each individual system. Each
of the seven phones is given a rank of priority when
programmed.
OPERATION
Incoming phone messages are transmitted to the
vehicle occupants through the vehicles audio sys-
