Lock and Unlock Commands

The VIM contains a radio receiver which is synchronized with the transmitter in the key fob (up to 4). The transmitter sends an RF signal with an identifier consisting of the following codes and message:
^ A fixed code-Sent in order to identify the fob as valid for the vehicle.
^ A variable code-Used in order to prevent the transmitter message from being recorded and to gain unauthorized access.
^ A message indicating the status of the LOCK/UNLOCK buttons-Indicates the requested function (lock/unlock).

The VIM will ignore received transmissions in the following situations:
^ The fixed code portion of the identifier is not valid.
^ The message portion indicates both lock and unlock functions are being requested.
^ The variable code portion of the identifier does not match the value stored in the VIM.

When the UNLOCK button on a valid fob is pressed once within a range of the vehicle in a 15 second period and ignition 1 (start or RUN) is not present at the VIM the following events occur:
^ The left door is unlocked.
^ The following lamps flash once for 250 msec:
^ The turn signals
^ The front park lamps
^ The front repeater lamps
^ The immobilization function will be disabled for 2 minutes then enabled. Allow the engine to run.
^ The dome lamps and the courtesy lamps are illuminated for 40 seconds. If a door is opened during the 40 second delay, the control is based upon the door jamb switch input unless the dome lamp defeat switch is active.

Whenever ignition 1 is detected at the VIM, the VIM will disable the interior lights output unless the door jamb switch input indicates a door is open.

When the UNLOCK button on a valid fob is pressed twice within range of the vehicle in a 15 second period and ignition 1 (START or RUN) is not present at the VIM, the following events will occur:
^ All events listed for a single button press.

The VIM will also react to lock/unlock signals from the power door lock switches. The circuits used by the VIM to lock/unlock the doors are also used by the VIM in order to monitor the state of these circuits.
