The ASD relay in the 2002 Jeep Liberty is essential for delivering 12 volts of power to the fuel injectors and ignition coils, which are crucial for providing fuel and spark to start the engine. Additionally, it controls the oxygen sensor heater circuit and signals the car to turn off when shut down. If the ASD relay malfunctions, you may have difficulty starting the engine, experience stalling right after starting, and see the "check engine" light come on. To find the ASD relay, check under the hood in the engine bay. The "R39" relay is linked to the Jeep's ASD and is located in the "power distribution box" on the driver's side of the bay near the firewall.
