COMPASS TEMPERATURE FUNCTION

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the Remote Compass Module (RCM) located above the headliner in the rear of the vehicle. Do not place any electronic devices (cell phones, laptop computers, PDAs, portable DVD players, etc), on or near the rear of the roof as the RCM performance may be effected. Do not use magnetic tools when servicing the RCM.

The Compass and Temperature data is obtained from several components on the Controller Area Network (CAN) and Local Interface Network (LIN) Data Bus circuits. The Compass Temperature Display will not function properly if the bus messages from any of these components is not received. If no Compass Temperature Display data is present or the display is inaccurate, check the CAN and LIN Data Bus circuit communications, the Instrument Cluster functions, the Remote Compass Module (RCM) and the Totally Integrated Power Module (TIPM). Should the RCM become disconnected or the signal from the RCM is lost, the instrument cluster will display dashes "- -".

The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the Instrument Cluster, the RCM, the CAN Data Bus and the LIN Data Bus circuits. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.

Some vehicles are equipped with the HomeLink® transceiver (1). The transceiver is located in the drivers side sun visor assembly (2). The only visible component of the HomeLink® transceiver are the three push buttons. The buttons are marked with one, two or three dots, respectively, for identification of each channel.

Each of the three HomeLink® transceiver push buttons controls an independent radio transmitter channel. Each of these three channels can be trained to transmit a different radio frequency signal for the remote operation of garage door openers, motorized gate openers, home or office lighting, security systems or just about any other device that can be equipped with a radio receiver in the 280 to 435 MegaHertz (MHz) frequency range for remote operation. The transceiver is capable of operating systems using either rolling code or non-rolling code technology. The system will not transmit operating signals if the Vehicle Theft Security System is armed.

The HomeLink® transceiver cannot be repaired, and is available for service only with the visor assembly. If any part of the component is inoperative or damaged, the complete visor assembly must be replaced. Refer to

The HomeLink® transceiver operates on a non-switched source of battery current so the unit will remain functional, regardless of the ignition switch position. For more information on the features, programming

procedures and operation of the HomeLink® transceiver, see the owner's manual.

If the HomeLink® transceiver is inoperative, retrain the transceiver with a known good transmitter, insuring the transmitter battery is OK. See STANDARD PROCEDURE for the proper procedure. Test the universal transmitter operation again. If the unit is still inoperative, test the universal transmitter with Radio Frequency Detector special tool as described below:

1. Turn the Radio Frequency (RF) Detector ON (3). A "chirp" will sound and the green power Light

Emitting Diode (LED) will light (2). If the green LED does not light, replace the battery (4). 2. Hold the RF detector within one inch of the TRAINED universal transmitter and press any of the transmitters buttons. 3. The red signal detection LEDs (1) will light and the tool will beep if a radio signal is detected. Repeat this test for all three transmitter buttons. If the tool does not detect a radio signal for any of the three buttons, replace the inoperative HomeLink® transceiver assembly. Refer to REMOVAL .

NOTE: Individual channels cannot be erased. Erasing the HomeLink® transceiver codes will erase ALL programmed codes.

To erase programming from all three buttons (individual buttons cannot be erased but can be "reprogrammed"), follow the step noted:

Press and hold the two outer HomeLink® transceiver 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 "Programming". See

WARNING: 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.

WARNING: Your motorized door or gate may open and close while you are training the HomeLink® transceiver if the vehicle is in range of the motorized device. Do not train the HomeLink® 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.

NOTE: When programming a garage door opener, it is advised to park outside the garage. It is also recommended that a new battery be placed in the hand-held transmitter of the device being programmed to the HomeLink® transceiver for quicker training and accurate transmission of the radio-frequency signal.

NOTE: If programing the HomeLink® transceiver is unsuccessful using the following procedure, refer to the Owner's Manual for the current customer assistance phone number.

1. Press and hold the two outer HomeLink® transceiver buttons, and release only when the indicator light begins to flash (after 20 seconds). Do not hold the buttons for longer than 30 seconds and do not repeat step one to program a second and/or third hand-held transmitter to the remaining two HomeLink®

transceiver buttons. 2. Position the end of your hand-held transmitter 3-8 cm (1-3 inches) away from the HomeLink® transceiver buttons while keeping the indicator light in view. 3. Simultaneously press and hold both the HomeLink® transceiver button that you want to train and the hand-held transmitter button. Do not release the buttons until step 4 has been completed. 4. The HomeLink® transceiver indicator light will flash slowly and then rapidly after HomeLink® successfully receives the frequency signal from the hand-held transmitter. Release both buttons after the indicator light changes from the slow to rapid flash. 5. Press and hold the just trained HomeLink® transceiver button and observe the indicator light. If the indicator light stays on constantly, programming is complete and your device should activate when the button is pressed and released.

NOTE: To program the remaining two buttons, begin with "Programming" step 2. Do not repeat step 1.

If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with "Programming" steps 6-8 to complete the programming of a rolling code equipped device (most commonly a garage door opener).

6. At the garage door opener receiver (motor-head unit) in the garage, locate the "learn" or "smart" button. This can usually be found where the hanging antenna wire is attached to the motor-head unit. 7. Firmly press and release the "learn" or "smart" button. (The name and color of the button may vary by manufacturer.)

NOTE: There are 30 seconds in which to initiate step 8.

8. Return to the vehicle and firmly press, hold for two seconds and release the programmed HomeLink® transceiver button. Repeat the "press/hold/release" 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.

The HomeLink® transceiver should now activate your rolling code equipped device.

NOTE: To program the remaining two HomeLink® transceiver buttons, begin with "Programming" step 2. Do not repeat step 1.

Canadian Programming/Gate Programming

Canadian radio-frequency laws require transmitter signals to "time-out" (or quit) after several seconds of transmission which may not be long enough for the HomeLink® transceiver to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to "time-out" in the same manner.

If you live in Canada or you are having difficulties programming a gate operator by using the "Programming"

procedures (regardless of where you live), replace "Programming HomeLink® Transceiver Codes" step 3 with the following:

NOTE: When programming a garage door opener or gate operator, it is advised to unplug the device or move the vehicle out of range during the "cycling" process to prevent possible overheating.

1. 3. Continue to press and hold the HomeLink® transceiver button while you press and release every two seconds ("cycle") your hand-held transmitter until the frequency signal has successfully been accepted. The indicator light will flash slowly and then rapidly. Proceed with "Programming" step 4 to complete.

WARNING: Vehicle exhaust contains carbon monoxide, a dangerous gas. Do not run the vehicle's exhaust while training the HomeLink® transceiver. Exhaust gas can cause serious injury or death.

WARNING: Your motorized door or gate may open and close while you are training the HomeLink® transceiver if the vehicle is in range of the motorized device. Do not train the HomeLink® 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.

NOTE: If programing the HomeLink® transceiver is unsuccessful using the following procedure, refer to the Owner's Manual for the current customer assistance phone number.

To program a device to the HomeLink® transceiver using a button previously trained, follow these steps:

1. Press and hold the desired HomeLink® transceiver button. DO NOT release the button. The indicator light will begin to flash after 20 seconds. Without releasing the HomeLink® transceiver button, proceed to step 2. 2. Position the end of your hand-held transmitter 3-8 cm (1-3 inches) away from the HomeLink® transceiver button while keeping the indicator light in view. 3. Simultaneously press and hold both the HomeLink® transceiver button that you want to train and the hand-held transmitter buttons. Do not release the buttons until step 4 has been completed. 4. The HomeLink® transceiver indicator light will flash slowly and then rapidly after it successfully receives the frequency signal from the hand-held transmitter. Release both buttons after the indicator light changes from the slow to the rapid flash. 5. Press and hold the just trained HomeLink® transceiver button and observe the indicator light. If the indicator light stays on constantly, reprogramming is complete and your device should activate when the button is pressed and released.

NOTE: If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with "Reprogramming" steps 6-8 to complete the

programming of a rolling code equipped device (most commonly a garage door opener).

6. At the garage door opener receiver (motor-head unit) in the garage, locate the "learn" or "smart" button. This can usually be found where the hanging antenna wire is attached to the motor-head unit. 7. Firmly press and release the "learn" or "smart" button. (The name and color of the button may vary by manufacturer.)

NOTE: There are 30 seconds in which to initiate step 8.

SENSOR-AMBIENT TEMPERATURE

For complete circuit diagrams, refer to SYSTEM WIRING DIAGRAMS article . The wiring information includes wiring 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.

NOTE: Temperature readings do not update immediately. Allow up to 60 seconds after the ignition switch is turned to the "ON" position for readings to meet test

1. Turn the ignition switch to the "OFF" position. Disconnect the wire harness connector from the ambient temperature sensor. 2. Turn the ignition switch to the "ON" position. The display should now read - 40° C (- 40° F). If OK, go to step 3. If not OK, repair the shorted sensor return circuit or ambient temperature sensor signal circuit to the ambient temperature sensor as required. 3. Turn the ignition switch to the "OFF" position. Taking care not to damage the wire terminals, connect a jumper wire between the two terminals in the body half of the ambient temperature sensor harness connector. 4. Turn the ignition switch to the "ON" position. The display should now read 60° C (130° F). If OK, go to step 5. If not OK, repair the open sensor return circuit or ambient temperature sensor signal circuit to the ambient temperature sensor as required.

NOTE: If the EVIC display does not show the ambient temperature in step 4, the vehicle may need to be driven several miles at a speed greater than 32 km/h (20 mph) for the temperature to update.

5. Turn the ignition switch to the "OFF" position. Remove the jumper wire. Turn the ignition switch to the "ON" position and wait until the display again reads - 40° C (- 40° F). Turn the ignition switch to the "OFF" position. Reconnect the ambient temperature sensor. Turn the ignition switch to the "ON" position. The display should now read the ambient temperature. If OK, the problem is intermittent. Perform further diagnosis while manipulating the related wire harnesses and components. If not OK, go to step 6. 6. Clear any Diagnostic Trouble Codes that may have been set while performing the test. Perform further diagnosis of the CAN data bus circuit, the LIN data bus circuit, the TIPM and the ambient temperature sensor (refer to SENSOR TEST).

1. Turn the ignition switch to the Off position. 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, further testing of the instrument cluster may be necessary. Refer to DIAGNOSIS AND TESTING for the appropriate procedure. If not OK, replace the inoperative ambient temperature sensor.

The Remote Compass Module (RCM) (2) is a separate stand alone module mounted to the top side of the headliner (1). The module is located at the rear left of the vehicle. The RCM can be accessed by removing both quarter trim panels and the headliner molding, then carefully lowering the rear of the headliner at the D-pillar area.

If the compass position sensor (Remote Compass Module) is inoperative and requires replacement. See REMOVAL for the appropriate procedure.

The Remote Compass Module (RCM) data is transferred on the Controller Area Network (CAN) Data Bus circuit. The RCM and Electronic Vehicle Information Center (EVIC)/Compass Temperature Display will not function properly if the bus messages are not properly received. If no EVIC/Compass Temperature Display data is displayed, check the CAN Data Bus circuit communications, the RCM, the Instrument Cluster functions and the Totally Integrated Power Module (TIPM). Any diagnosis of the RCM and EVIC/Compass Temperature Display system should begin with the use of a scan tool and the appropriate diagnostic service information.
