Door Lock Control Processor, Electronic

- The electronic door lock control processor is located behind the instrument panel.
- It contains a radio receiver that receives the LH signal from the keyless entry remote transmitter through the alarm and lock system antenna and sends the appropriate command to the power door locks, the horn relay, the indicator flasher, or the anti-theft alarm control (if equipped).
- The electronic door lock control processor is equipped with a battery backup which holds the programmed code in memory in the event the vehicle battery is disconnected.
