All LEDs are blinking rather than alternating?

Question

2012 Ram 1500 standard key. after installation and wiring ready for programming, i plugged the data connector I just had all LEDs blinking. the first unit was replaced and i have the 2nd now but still the same, is there a problem on the unit itself or just my vehicle?

Answer 1

The 3 LEDs flashing when you hold the programming button while inserting the power connector, indicate that the module was never flashed to the firmware appropriate to the vehicle it is being installed in.
