System Description

The Keyless Entry Receiver is designed with an internal antenna. The Receiver picks up transmitted Radio frequencies from a hand held Transmitter with sufficient power to operate the system from up to 7 to 10 meters (22 to 33 ft.) from the Receiver.

TRANSMITTER FUNCTIONS

Lock

When the Lock Button is pressed, the Receiver grounds the "Lock All" coil of Relay # 1, causing both Door Lock Actuators to lock. The Receiver also grounds the "Illumination" coil of Relay # 2 for two seconds. This provides visual confirmation that a lock function was performed.

Unlock

When the Unlock Button is pressed once, the Receiver grounds the "Unlock Driver" coil of Relay # 1, causing the Left Hand Door Lock Actuator to unlock. To provide an illuminated entry, the Receiver also grounds the "Illumination" coil of Relay # 2 for forty seconds or until the Receiver sees an Ignition "ON" input.

When the Unlock Button is pressed twice, the second must be within five seconds of the first, the Receiver grounds the "Unlock All" coil of Relay # 2, causing both actuators to receive unlock signals.

Hatch Release

When the Hatch Release Button is pressed, the Receiver grounds the "Hatch Release" coil of Relay # 3. With Relay # 3 closed, the Hatch Release Relay is energized and applies battery voltage to the Hatch Release Actuator, releasing the Hatch. To provide hatch area illumination, the Receiver also grounds the "Illumination" coil of Relay # 2 for forty seconds 0 until the Receiver sees an Ignition "ON" input. The Hatch Release Function operates only when the vehicle is in park or neutral (Automatic Transmission or the Parking Brake is applied (Manual Transmission). The Hatch Release Function is disabled as soon as the Keyless Entry Receiver sees an Ignition "ON" input.

Illuminated Entry Operation

The keyless Entry Receiver provides a ground to turn on the Dome Lamp for illuminated entry whenever a Transmitter request is received.

- With a "Lock" request, the Dome Lamp is turned on for two seconds to provide visual confirmation that a lock function was performed.
- With an "Unlock" or "Hatch Release" request the Dome Lamp is turned on for forty seconds to provide illuminated entry and hatch area illumination.

The illuminated entry time cannot be extended by pressing the Lock, Unlock or Hatch Release Button until it has timed out. Illuminated entry is disabled as soon as the Keyless Entry Receiver sees an ignition "ON" input at terminal "D" of connector C1.

Power Door Locks

The Door Lock Actuators always receive ground through the Power Door Lock Switches from G200. Battery voltage is applied to the actuators either from the "PWR ACCY" Fuse 7 when the Power Door Lock Switches are used, or from the "Courtesy" Fuse 8 when the Keyless Entry Receiver sees a request from the Transmitter.
