Message Center Control Assembly Switch Module

The message center is only available on vehicles equipped with an Electronic Instrument Cluster (EIC). The message center receives signals from the Vehicle Speed Sensor (VSS), fuel tank sending unit, outside air temperature sensor, and the Powertrain Control Module (PCM).

The message center goes through a prove out when the ignition switch is turned to the ON position. The message center then resumes the mode of operation last used.







Directly below the message center is the Message Center Control Assembly (MCCA) switch module. The MICA includes the following controls:
- SELECT
- RESET
- ENG/MET
- TRIP/RST
- OD/TRIP

SELECT
The SELECT button moves the message center cursor to the desired display.

ENG/MET
The ENG/MET button switches the EIC displays to read in either English or metric measurement. Upon starting the vehicle, the EIC will return to the units displayed before shut off.

RESET
The RESET button will return the average fuel economy display (AVG ECONOMY) to zero.

TRIP/RST
The TRIP/RST button will clear the trip distance displayed on either the TRIP 1 or TRIP 2 displays.

OD/TRIP
The OD /TRIP button will switch the odometer display between TRIP 1, TRIP 2, and odometer.
