Concorde V6-2.7L VIN R (1998)
The 1998 and 1999 LH has several customer programmable features which can be disabled or enabled by the customer.
Bus Failure Message
Odometer Displays "No Bus" - The Mechanical Instrument Cluster (MIC) cannot communicate over the bus and does not know why.
Chime System
The chime system is comprised of an audible chime located internal to the Body Control Module (BCM); and is dependent on various inputs to the
BCM to operate. These inputs include key-in ignition switch, exterior lamps, seat belt switch, and requests from the Mechanical Instrument Cluster
(MIC) to chime when some indicators are turned on.
(ATC) Automatic Temperature Control
The body control module (BCM) provides for automatic temperature control support both through PCI bus communications and through processing
inputs to determine control for actuators and the blower motor. The BCM interfaces with the ATC control head over the PCI bus. Information on button
activation, blower setting, and temperature setting are supplied to the BCM. In turn, the BCM supplies the ATC control head with mode information and
indication lamp status. The BCM controls blower motor speed by providing a varying duty cycle of a fixed frequency output (pulse width modulation).
