Instrument Cluster / Carrier: Description and Operation

Autostick Odometer/Transmission Range Indicator:

AUTOSTICK
Vehicles with Autostick Will have a unique Transmission Range Indicator display.

When in the Autostick mode, a box around the gear position will be displayed to inform the driver which transmission gear is currently engaged.

Instrument Cluster:

ELECTRO-MECHANICAL INSTRUMENT CLUSTER
The cluster includes:
- 150 mph (240 kph) speedometer
- Odometer/trip odometer and transmission range indicator with autostick transmission
- Fuel gauge
- Oil gauge
- Voltage gauge
- Temperature gauge

The warning and information indicators include the following:
- Service Engine Soon (ISO Symbol)
- Airbag
- CHECK gauge
- Low fuel
- Seat belt
- Cruise
- Brake/park brake
- High beam
- Low washer fluid
- Low tire
- Vehicle Theft Security System alarm LED indicator
- Turn signals
- Pass Airbag Off

The mechanical instrument cluster is an electro/mechanical module. The gauges are the magnetic air core type.

The electro/mechanical instrument cluster receives most of its information from the Body Control Module (BCM) via the CCD bus. When the ignition switch is OFF, the gauge pointers should rest at or below the low graduation.

Data Link Connector Location:

DATA LINK CONNECTOR
Data link connector is located on the lower full left side of the instrument panel.

The Data Link Connector is used to communicate with the DRB III scan tool and Mopar Diagnostic System (MDS) machine to aid in diagnosis of vehicle problems.

ODOMETER/TRANSMISSION RANGE INDICATOR
The Odometer/transmission Range Indicator is part of the Speedometer and is not serviced separately.

The Odometer/Transmission Range Indicator is used to display vehicle mileage and display shift lever position.

The Odometer receives its signal from the vehicle speed sensor and relays vehicle speed information through the BCM to the odometer display.

The Transmission Range Sensor (TRS), communicates shift lever position to the TCM as a combination of open and closed switches. Each shift lever position has an assigned combination of switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets transmission gear position and shift schedule. The TCM them relays this information to the Transmission Range Indicator through the BCM.
