Keyless Entry: Description and Operation

CIRCUIT OPERATION
The Keyless Entry System includes a hand held radio Transmitter and Keyless Entry Module. The Transmitter sends digitally encoded radio signals to the module when a button is pushed. The following circuits can be controlled:
1. Illuminated Entry lights.
2. Door locks (all doors or just driver's).
3. Tailgate and Luggage Compartment Lid Release.

Transmitter range is 7 meters (23 feet).

Illuminated Entry
The RKE Module grounds the Interior Lights for approximately 40 seconds when a door unlock signal is received by the RKE Module, or until the Ignition Switch is turned to RUN.

Door Locks
If the RKE Transmitter Unlock Button is pressed once, the driver's door will be unlocked. The RKE Module receives the transmitted signal and activates its output at C2/C. This applies battery voltage directly to the LH Front Door Lock Motor, which is grounded through the Door Lock Relay Assembly.

Pushing the Unlock Button twice within 5 seconds results in the RKE Module activating its outputs at C2/D and C2/C. The Driver's Door Motor is driven directly by the RKE Module as described above. The Unlock Relay in the Door Lock Relay Assembly is energized, causing the passenger's doors to unlock.

The Tailgate and Luggage Compartment Lid Release is operated by applying battery voltage directly to the Release Solenoid when the Tailgate or Luggage Compartment Lid Release Button is pressed on the Transmitter.

The Tailgate Release will only function when there is no voltage present at the Ign On Input, terminal C1/B. This allows the Tailgate to be opened with the Ignition Switch in ACCY, LOCK and OFF and the transaxle in any gear.

The Luggage Compartment Lid Release will only function when the Enable Input, terminal C1/G, is grounded. This allows the Luggage Compartment to be opened with the transaxle is Park or Neutral and the Ignition Switch in any position.
