Description
DESCRIPTION
The instrument panel switch pod (also known as the center console switch unit, Switch Bank Module/SBM, Upper Control Panel/UCP or OBF) (2) is
located just below the heater and air conditioner controls in the center bezel (1) of the instrument panel. This switch is available in multiple
configurations, which vary from vehicle to vehicle to include as many as eleven push button switches, depending upon the optional equipment in the
vehicle. The pod may include the following switches:
-
Acceleration Slip Regulation (ASR) OFF (also known as Traction Control) (7)
-
Central Locking (Interior or Rear Compartment (9)
-
Electric Rear Window Defogger (5)
-
Electric Windshield Defogger (6)
-
Hazard Warning (8)
-
Heated Seat (Driver and Passenger Side) (4)
-
Park Assist OFF (also known as ParkTronic System/PTS) (10)
-
Power Sliding Doors (Driver and Passenger Side) (3)
The switch housing and the push buttons are constructed of molded plastic. Each push button has a smooth finish and is clearly identified with the
appropriate text or International Control and Display Symbol icons. Several of the push buttons feature Light Emitting Diode (LED) units and small
plastic jewels to give the vehicle operator an indication when the function of that switch is currently active. Only the hazard warning switch push button
latches, while the remaining switches feature momentary operation.
Four screws secure the switch to the back of the instrument panel center bezel through integral mounting tabs that are molded into the switch housing.
The back of the switch housing has an integral connector receptacle containing terminal pins that connect the switch pod to the vehicle electrical system
through a dedicated take out and connector of the instrument panel wire harness.
Panel lamps dimmer controlled illumination lamps integral to the circuit board within the switch provide back lighting for visibility at night, but these
lamps are not serviceable. The individual switches in the instrument panel switch pod cannot be repaired and are not serviced individually. If any
component within the switch pod is ineffective or damaged, the entire switch pod unit must be replaced.
