2015 Focus ST. MT/PTS/IA - No TX/RX Wires and more

0 votes
I talked to someone on the phone about this briefly.

 

2015 Focus ST.

Manual transmission.

PTS

Intelligent access.

 

 

This car does not have TX/RX wires. I work at a ford dealer and confirmed through the diagrams. ADS confirms some cars are this way and is in "development".

Viper w/evo all

 

However:

- Trying to program the kit without Tx/rx to the car, I can get "some" of it to work.

- Unlock through CAN works. Lock does not. There IS NO lock wire in the car. Everything is data or RF (Or needs to see fob RF OUTSIDE of the car, then the intelligent access lock wire inside the handle will work. As soon as the fob is moved inside the car, that circuit will not lock the doors. The wire does trigger when you touch the button on the outside of the door, but the car doesnt respond unless the fob is outside. ) . The only way to do lock without the right firmware would be to maybe go to the switch in the door, or hardwire a relay to the all-lock wire are the BCM which goes straight out to the motors in the door. (AKA old-school reverse polarity locks)

- RAP shutdown not working off the evo.
 

- Without CAN hooked up, you need to power up second start-switch wire. With can hooked up its ok without. I would have done it without the kit at all, but then you have a shut-down problem. If I was using an Astro-Start, the outputs are configurable enough to set up a separate shut-down output. But the Viper is not and I have to rely on the evo to actually shut off the car when required by the starter but not shut it off accidentally when running by the driver.

- Brake output (for start) on the EVO does not work. Brake on the bus/D2D kills the starter when starting while powering up the brake wire. So, disable brake status. Wire brake input and start output from the brain to a relay then to the car. Thus when starting the relay energizes and the starter does not see a brake signal. Once crank pulse is over, relay de-energizes and brake shutdown works.

- Ebrake status does not work properly in W2W. Hardwired ebrake to car instead.

- Door status, Hood status, tach is working D2D

- It seems there are 3 clutch switches in the car. Upper and Lower at the pedal plus one on the transmission. Grounding the wires at the pedal will get the car the car to start but triggers "engine fault" warning. Warning goes away when started by depressing the clutch. Will not trip a permanent light but will log a hidden code indicating a problem with the clutch switches. At this point I am not even going to try the last switch at the trans/pcm.

 

No typical transponder setup for key-wrap. Take the battery out of the key and put it in the center console, car will start. I tried wrapping the key and putting it inline with the antenna wires going to the keyless access module and couldnt get it to start. I dont have an INSET in stock so I am going to maybe try wiring a relay to the power circuit in the fob to power it up/down with GWR. But not sure if it needs a lock or unlock push to "re-awaken" the fob or not.

 

Big huge ass pain right now. Im about ready to pull it out and await proper firmware, but the customer "really" wants this. I am 10 hours in and still need to wire lock, transponder and RAP shutdown! (But now since the evo isnt actually controlling rap, I worry it will send a door-open signal to the starter, killing ready mode. Argh.

Jeremy, want to send us the VIN (or picture of the VIN) and also the service number of EVO-ALL to support@ifar.ca ? you can post it here if you like. We need the vehicle plans to figure this one out. The VIN will help with this and also helps engineering.

That's what she said. Joking aside, we're looking at some vehicle schematics right now. The VIN might help in case of descrepancies. If this vehicle is really different, there is nothing we'll most likely be able to do until we see one of these vehicles.

 

I'll have more questions in a bit.

It seems as though it's a mid year change and this change has not affected any of our local dealers yet. We are wondering if the vehicle would be a similar install as the new Fusion/F150.

If you want, along with the VIN and service number, we need pics of the dash, the key, and the RF connector.
