Homelink(r) Universal Transmitter
The HomeLink Universal Transmitter is optional with the standard overhead console. For added security it will operate home security systems that
use coded signals known generically as rolling codes to increase security. The overhead console display provides visual feedback to the driver,
showing which HomeLink transmitter button is pressed. As on prior models, HomeLink can learn and store three separate transmitter radio
frequency codes to operate garage door openers, security gates, and security lighting. Buttons are marked with one, two or three raised dots for
identification by touch.
Self-Diagnostic Test
The self-diagnostic test is used to determine that the internal circuitry and compass are operating properly, and all PCI bus messages are being
received for initial operation. The button backlighting is also verified by flashing the bulbs for proper operation.
Initiate the self-diagnostic test as follows:
1. With the ignition switch in the OFF position, simultaneously press and hold the C/T button and the RESET button.
2. Turn the ignition switch to the ON position.
3. Continue to hold both buttons until the software versions are displayed.
4. The display will show the result of the self-diagnostic test. If the display reads:
a. PASS SELF TEST - press the RESET button to return to the compass/temperature display. The EVIC is working properly.
b. FAILED SELF TEST - an internal failure has occurred. Replace EVIC.
c. FAILED J1850 COMMUNICATION - see diagnostics for further information,
Ambient Temperature Sensor
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, the Powertrain Control Module (PCM), the
Programmable Communications Interface (PCI) data bus, and portion of the Electronic Vehicle Information Center (EVIC) module. If any portion
of the ambient temperature sensor circuit fails, the PCM will self-diagnose the circuit and set a DTC.
The EVIC will lock the display at 54 °C (130 °F) if the sensor is exposed to temperatures above 54 °C (130 °F), or if the sensor is shorted. The
EVIC will lock the display at -40 °C (-40 °F) if the sensor is exposed to temperatures below -40 °C (-40 °F), or if the sensor circuit is open.
POWER DOOR LOCK SYSTEM
The door lock switches provide a variable amount of voltage through the multiplexed (MUX) circuit to the BCM. Depending upon that input and
various conditions that must be met (i.e. door lock inhibit, etc.), the BCM will determine the action to be taken and activate the proper relay for
approximately 250 to 350 msec. If the vehicle is equipped with the vehicle theft security system it will have the central locking feature which locks
and unlocks all doors from the cylinder lock switches. These switches are on separate multiplexed circuits to the BCM and have trouble codes
relating to each of them.
RKE Remote Keyless Entry - This feature allows locking and unlocking of the vehicle door(s) by remote control using a hand-held transmitter
(sometimes referred to as a fob) to activate a radio receiver (RKE module). This module now plugs into the body control module which is directly
connected to the junction block. With this feature RKE can now be added to a non-equipped vehicle by installing a module. If the vehicle is
equipped with the vehicle theft security system, RKE will also arm and disarm that system. A 4-button transmitter is used which provides lock,
unlock, decklid release and panic features. Decklid release is only operable while the vehicle is in the park position. The module is capable of
retaining up to 4 transmitter codes. Rolling code, which increases security, is also included in this system. If the transmitter goes out of
synchronization it is easily put back in by pressing the lock button when the transmitter is within range. An external antenna has been added which
