Flash programed the EVOALL and now it won't program in the car

0 votes
I flashed the evo to the recommended firmware and now I cannot reprogram in the vehicle. It will only enter into the learn mode. Will not turn the yellow LED on when I turn the key to the run position. I even purchased a second EVOALL and flashed it and get the same results.

Make sure you have connected the yellow accessory wire from the EVOALL 20 pin connector to the BROWN accessory wire of the vehicle. You can also test this wire with a DMM, it should should 0v when key is off or key is at start, and 12V when key is on accessory or ignition position.
