Grand Caravan AWD V6-201 3.3L (1992)
The electronic cluster includes a digital speedometer, odometer, oil pressure gauge, coolant temperature gauge, fuel gauge, and voltage gauge. It also has
a series of warning indicator lamps designed to provide the driver with valuable information to ensure the vehicle is operating properly.
The electronic cluster receives virtually all of the information for its displays from the body controller and the engine controller via the CCD multiplex
system.
The electronic cluster has two forms of diagnostic routines that are used to isolate problems within the cluster: self-diagnostics and CCD bus diagnostics.
Self-diagnostics are accessed by simultaneously depressing the TRIP and TRIP RESET buttons. CCD bus diagnostic routines require the use of the
DRBII diagnostic readout box.
Successful completion of the self-diagnostic test indicates if the problem is in the CCD bus, interfacing modules, connectors, wiring harnesses, or sensors
outside the cluster.
The body controller (not the Electronic Instrument Cluster) stores the odometer information that is displayed on the instrument cluster. Therefore, when
replacement of the electronic cluster is required, the odometer reading will not be affected. (See the "Body Controller" description found earlier in this
section.)
Functional Operation
Diagnosis of vehicle systems other than the body system uses the DRBII to read hard fault messages. The reason for the fault is then diagnosed to find
the source of the problem. When a body system does not operate properly, a warning code will appear or the customer will describe a complaint.
The body systems are monitored by individual control modules which send information about their operation to the body controller.
General Description
The AS body system consists of a combination of modules that communicate over the CCD (Chrysler Collision Detection multiplex system) bus.
Through the CCD bus, information about the operation of vehicle components and circuits is relayed to the appropriate module(s). Each module receives
the same information about a component or circuit as another module does. This significantly reduces the complexity of the wiring in the vehicle and the
size of the wiring harnesses.

Identification of System
Vehicles equipped with the air bag system can be identified by the presence of an extra large horn pad in the center of the steering wheel, bearing the
SRS air bag logo.
The following options, available on all 1992 AS body vehicles, are located as follows:
Auto Door Locks - This option, located on each front door trim panel, will "Lock" and "Unlock" the doors by pressing the door lock switch toward the
desired function.
Compass Mini-Trip - This option, located in the overhead console, displays information on outside temperature, compass direction, and trip
information.
Courtesy Lamps - Located on each front door trim panel and overhead console (if equipped). System includes the rear dome lamp.
Electronic Instrument Instrument Cluster - This option, located in front of the steering wheel inside the dashboard, has digital readouts for:
Speedometer, Odometer & Trip Odometer W/Reset. Digital graphic displays for: Tachometer, Oil Pressure, Fuel, and Temperature.
Electro/Mechanical Cluster - This option, located in front of the steering wheel inside the dashboard, has analog readouts for: Speedometer, Odometer,
and a Trip Odometer w/Reset. Analog gauges for: Fuel and Temperature. Lights for: Low Fuel, Oil Pressure, Voltage, Liftgate Ajar, and Check Engine.
Illuminated Entry - This option has a white switch connected to the door handle mechanism inside each front door.
Intermitent Wipers - Standard.
