One key troubleshooting: The first 4 steps are only for mode selection. If you cannot pass these steps then their is an issue with one of the following: 1-Firmware is incorrect for the vehicle. Verify you have flashed the proper firmware to the vehicle. 2-Yellow wire (A1) already has 12 volts present on it and it should have 0 Volts on it at this time. 3- Power & Ground Verify the power and ground being supplied to the module. Two key troubleshooting: Timing is crucial When cycling the keys! Ensure you are counting 3 seconds per key this is crucial in getting the module to program correctly.
