5. Press and hold the just trained HomeLink button and observe the EVIC display. If the EVIC display shows
“Channel X Transmit” (where X is Channel 1, 2, or 3), programming is complete and your device should activate
when the HomeLink button is pressed and released.
NOTE: To program the remaining two HomeLink buttons, begin with

step two. Do not repeat
step one.
NOTE: If your hand-held transmitter appears to program the universal transceiver, but your garage door
does not operate using the transmitter and your garage door opener was manufactured after 1995, your
garage door opener may have a multiple security code system (rolling code system). Please proceed to
steps 6–8 to complete the programming of a rolling code equipped device (most common garage door
openers require this step.
6. At the garage door opener receiver (motor-head unit) in the garage, locate the

usually be found where the hanging antenna wire is attached to the motor-head unit.
7. Firmly press and release the

button. (The name and color of the button may vary by manu-
facturer.)
NOTE: There are 30 seconds in which to initiate step eight.
8. Return to the vehicle and firmly press, hold for two seconds and release the programmed HomeLink button.
Repeat the

sequence a second time, and, depending on the brand of the garage door
opener (or other rolling code equipped device), repeat this sequence a third time to complete the programming.

ERASING TRANSMITTER CODES
NOTE: Individual channels cannot be erased. Erasing the transmitter codes will erase ALL programmed
codes.
To erase programming from the three buttons (individual buttons cannot be erased but can be

),
follow the step noted:
•
Press and hold the two outer HomeLink buttons until the indicator light begins to flash-after 20 seconds.
Release both buttons. Do not hold for longer that 30 seconds. HomeLink is now in the train (or learning) mode
and can be programmed at any time beginning with

(Refer to 8 - ELECTRICAL/OVERHEAD
CONSOLE/UNIVERSAL TRANSMITTER - STANDARD PROCEDURE).
REPROGRAMMING TRANSMITTER CODES
CAUTION: Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run the vehicle’s exhaust
while training the transceiver. Exhaust gas can cause serious injury or death.
CAUTION: Your motorized door or gate will open and close while you are training the Universal Transceiver.
Do not train the transceiver if people or pets are in the path of the door or gate. A moving door or gate can
cause serious injury or death to people and pets or damage to objects.
To program a device to HomeLink using a HomeLink button previously trained, follow these steps:
1. Press and hold the desired HomeLink button. Do NOT release the button.
2. The EVIC display will show “Channel X Transmit” (where X is Channel 1, 2, or 3) for 20 seconds and then
change to “Channel X Training”. Without releasing the HomeLink button, proceed to step 3.
3. Position the end of your hand-held transmitter 1-3 inches (3-8 cm) away from the HomeLink buttons.
4. Simultaneously press and hold both the HomeLink button that you want to train and the hand-held transmitter
buttons. Do not release the buttons until step 4 has been completed.

SENSOR-AMBIENT AIR TEMPERATURE
DESCRIPTION
The ambient temperature sensor is a variable resistor
mounted to a bracket that is secured with a screw to
the left side of the radiator yoke, behind the radiator
grille and in front of the engine compartment.
The ambient temperature sensor cannot be adjusted
or repaired and, if inoperative or damaged, it must be
replaced.
OPERATION
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent by the Front
Control Module (FCM). The resistance in the sensor changes as temperature changes, changing the temperature
sensor signal circuit voltage to the FCM. Based upon the resistance in the sensor, the FCM senses a specific volt-
age on the temperature sensor signal circuit. The FCM then translates the voltage into a temperature reading that
it sent over the Programmable Communications Interface (PCI) data bus circuit to other modules utilizing temper-
ature information.
DIAGNOSIS AND TESTING
AMBIENT TEMPERATURE SENSOR
The temperature function is supported by the ambient temperature sensor, a wiring circuit, and Front Control Module
(FCM). If any portion of the ambient temperature sensor circuit fails or if Programmable Communications Interface
(PCI) Data Bus information is missing, a (– –) will appear in the display in place of the temperature. When the
DR/DH
OVERHEAD CONSOLE - SERVICE INFORMATION
8M - 37
sensor is exposed to temperatures above 55° C (130° F), or if the sensor circuit is shorted, 55° C (130° F) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures below - 40° C (- 40°
F) or if the sensor circuit is open, - 40° C (- 40° F) will appear in the display.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test, and Sensor Circuit
Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or
incorrect, test the compass mini-trip computer (Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE/COMPASS/MINI-
TRIP COMPUTER - DIAGNOSIS AND TESTING).
SENSOR TEST
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the
ambient temperature sensor harness connector.
2. Measure the resistance of the ambient temperature sensor. At - 40° C (- 40° F), the sensor resistance is 336
kilohms. At 55° C (130° F), the sensor resistance is 2.488 kilohms. The sensor resistance should read between
these two values. If OK, refer to Sensor Circuit Test in this group. If not OK, replace the inoperative ambient
temperature sensor.
SENSOR CIRCUIT TEST
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wir-
ing diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector
pin-out information and location views for the various wire harness connectors, splices and grounds.
1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the wire
harness connectors from the ambient temperature sensor and the FCM.
2. Connect a jumper wire between the two terminals in the body half of the ambient temperature sensor harness
connector.
3. Check for continuity between the sensor return circuit and the ambient temperature sensor signal circuit cavities
of the FCM harness connector. There should be continuity. If OK, go to Step 4. If not OK, repair the open sensor
return circuit or ambient temperature sensor signal circuit to the ambient temperature sensor as required.
4. Check for continuity between the ambient temperature sensor signal circuit cavity of the FCM harness connector
and a good ground. There should be no continuity. If OK, test the compass mini-trip computer operation, (Refer
to 8 - ELECTRICAL/OVERHEAD CONSOLE/COMPASS/MINI-TRIP COMPUTER - DIAGNOSIS AND TESTING).
If not OK, repair the shorted ambient temperature sensor signal circuit as required.
REMOVAL
1. Open the hood.
2. Disconnect and isolate the battery negative cable.
3. Working on the underside of the hood, remove screw holding sensor to hood panel.
4. Disconnect the sensor electrical connector and remove sensor from vehicle.
INSTALLATION
1. Connect the sensor electrical connector.
2. Working on the underside of the hood, install screw holding sensor to hood panel.
3. Connect the battery negative cable.
4. Close the hood.
