Programming failure 2015 Ford Fusion standard Key w/ standalone + THAR-FOR2

0 votes
Following instruction 59421 to install a stand-alone system with THAR-FOR2, I get to step 9 in the key bypass programming section. The vehicle's ignition turns on, but the blue light never flashes rapidly.

I've confirmed that the firmware is 71.46, and the 3 wires (Light Blue, Light Blue/Black, and Yellow) that come from the T-harness are properly crimped to the wires going to pins A20, A10, and A1. (crimped, and applied adhesive lined heat-shrink)

The CAN connections were connected to the wires at the pins as depicted on page 4 of the instructions - I noticed an error in the instructions, pin 20 on the diagnostic connector had a solid blue wire, rather than White/Blue. This wire was going to pin 20, and was twisted with the white wire on pin 19.  To confirm proper connections, with the connector unplugged from the Evo All, I measured resistance between C1 & C2 to be 62ohms, and between C3 & C4 to be 61ohms - consistant with a standard CAN network.

I've tried switching C1 with C2, I've also tried switching C3 with C4 - no improvement.

 

Any help to get past step 9 will be appreciated.

CAN is easy to test. Just program CAN on it's own. 

  1. Hold button in while connecting black connector and release on blue
  2. Plug in all connectors.
  3. Turn key on, blue led will start to flash
  4. turn key off. 

 

For the normal programming, the BLUE will not flash for either CAN or if it cannot properly read the key. 
 

Things to watch for on any Ford 2 key programming since it is the factory procedure to program a spare key to the car.
 

-- Master keys required. A cloned key will not act as key2. if it's a clone of key1, it is still key1. 

-- After turning Key1 and Key2 ON, start counting 3 full door chimes before turning the car off.

-- If the BCM does not have Spare Key Programming enabled, 2 key programming will not work.
