<h1>1994 GMC Sonoma — Keyless Entry Remote Programming Instructions</h1> <p><font size="3">The 1994 GMC Sonoma supports onboard programming for keyless remotes using a jumper wire and the vehicle’s diagnostic port. Follow these detailed steps to successfully program your remote(s). </font></p> <p><font size="3"><b>Remote Programming Procedure</b> </font></p> <ul> <li><font size="3">Step 1: Access the Data Link Connector (DLC) Locate the diagnostic port beneath the dashboard on the driver's side. The connector may not be labeled, so refer to a pinout diagram to identify the correct cavities. Look directly into the connector—terminal G is usually found in the top row (far left position depending on orientation). </font></li> <li><font size="3">Step 2: Initiate Programming Mode Using a fused jumper wire, bridge terminal G to a grounded metal surface. Within two seconds, the vehicle will automatically cycle the door locks (lock then unlock) to indicate it's in programming mode. </font></li> <li><font size="3">Step 3: Program the First Remote Press any button on the first remote control. The door locks should cycle once again to confirm the signal was accepted and the remote is now paired. </font></li> <li><font size="3">Step 4: Program Additional Remotes If you have more remotes to program, press any button on the next remote within a few seconds. The locks will again cycle to indicate each new remote has been successfully learned by the system. </font></li> <li><font size="3">Step 5: Exit Programming Mode Disconnect the jumper wire from the DLC port and the grounded surface. Test all remotes by locking and unlocking the doors to verify proper functionality.</font></li> </ul>
