- 1). Park the Saturn VUE. Engage the parking brake. Open the hood and secure it using the safety bar. Disconnect the black negative battery cable by loosening the nut on the clamp around the battery post using an adjustable wrench. Pull it up and set it away from the battery.
- 2). Find the engine relay center located between the battery and the firewall. Release the cover unscrewing the screws on either side of the cover. Set the cover aside. Look for the relay labeled ABS. On each side of the relay, there is a screw. Remove these screws using a Phillips screwdriver. Pull up on the relay to remove it.
- 3). Unhook the wiring harness on the bottom of the relay by pressing the buttons on the side of the harness. Gently pull down on the harness while you are pressing the buttons.
- 4). Plug the wiring harness into the bottom of the new ABS relay. Place the new ABS relay in the place from which you just removed the malfunctioning relay. Secure it by replacing the mounting fasteners. Tighten them with the screwdriver. Replace the cover and secure it with the clips.
- 5). Reconnect the negative battery cable. Tighten the nut on the clamp. Close the hood. Start the engine. Look for the ABS warning light. If it remains off, test drive your vehicle by driving slowly and trying to stop. If the ABS warning light comes on, take it to a mechanic to service the system.
