Cause The cause of these concerns could be one of many di erent possibilities. Correction: The information below is only for reference and normal SI diagnostics and programming instructions should always be followed. When having di culties programming or learning key fob transmitters to a vehicle, the following tips may help. 1. If programming new key fobs, verify the correct part number fob is being used. Also, make sure there is not a VIN already learned to the new key fob by using the EL-52545 and follow the latest version of bulletin 21-NA-061. 2. Do not assume where the programming fob pocket is located, as it can vary from vehicle to vehicle. Use the owner's manual to verify the proper location of the programming fob pocket. NOTE: If there is still a fob transmitter programmed to the vehicle, one quick test to determine that the IMMO coil is working properly and you have the correct programming fob pocket location, is to perform the following: - Remove the battery from the fob that is still programmed to the vehicle. - Move all fobs away from the vehicle. - Try to start the vehicle and the results should be a DIC message stating no fob detected. - Place the learned fob, with the battery removed, into the programming fob pocket and try to restart or power up the vehicle. If the vehicle powers up, then you have veri ed the IMMO coil is working properly, and the correct programming fob pocket is being used. 3. If there was any reprogramming, a module replaced, or any modules with a current DTC U1962, then make sure the Serial Data Authentication Con guration (SDAC) has completed. 4. If there are any "Environment Identi er" DTC's set, they should be addressed. 5. During the IMMO Immobilizer Learn, after the ignition automatically powers on, make sure to set the parking brake. Also, on vehicles with a Electronic Transmission Range Shifter, press the "Park" button on the shifter. 6. During the IMMO Immobilizer Learn, only place the key fob transmitter in the programming fob pocket when instructed, and make sure ALL additional transmitters are AT LEAST 3 m (9.8 ft) away from the vehicle. Do NOT place key fob transmitters on the roof, hood, etc. keep them away from the vehicle. 7. During the IMMO Immobilizer Learn, stay with the TLC computer and vehicle at all times so you can follow ALL programming instructions, as SPS will instruct multiple times to perform various functions. If these instructions are missed, the learn could fail. 8. During the IMMO Immobilizer Learn a "Communication Error" message maybe displayed. This error has been seen when an aftermarket device is connected inline with the DLC, see the latest version of bulletin 13-08-116001H. Inspect and remove any aftermarket devices. 9. In some rare cases, if the computer/lap top being used to do the IMMO Immobilizer Learn is inside the vehicle it, could cause interference. Make sure the computer/lap top is outside the vehicle when performing the IMMO Immobilizer Learn. Version History Version Modi ed 1 05/11/2023 - Created on. © 2023 General Motors. All Rights Reserved.
