Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Section 40 (Universal Transmitter - 1500 Classic): Operation
The HomeLink® transceiver receives battery feed through the Ignition Off Draw (IOD) fuse circuit of the vehicle. It operates on a non-switched source of battery current so the unit will remain functional, regardless of the ignition switch position. It can learn and store three separate transmitter radio frequency codes to operate garage door openers, security gates and security lighting. The Electronic Vehicle Information Center (EVIC) display provides visual feedback to the driver, showing which transmitter button is pressed. The system will not send operating signals if the vehicle theft security alarm is armed. This prevents a perpetrator from breaking into a vehicle parked outside a home and using the HomeLink® transceiver system to enter the home.
