What it does
Ford's factory collision detection unlocks the doors if the car detects a crash, so occupants can get out and help can get in. When a Haltech Elite replaces the factory ECU, the Ford Travel Assistance Service function carries that safety feature over. It reads the collision signal and passes the unlock request on to the car.
On the Ford Pro plug-in setup, such as the Elite Pro Plug-in ECU, there's nothing to wire. On the Wiring tab:
- Input is filled in for you as the OEM collision detection input.
- Output is set automatically to the vehicle CAN bus.
When to turn it off
The function expects the factory Travel Assistance Service module to be in the car. If that module has been removed, which is common on stripped race cars and some swaps, the ECU won't find it and will log a diagnostic trouble code. In that case, disable the function and the code goes away.
If the factory module is still fitted, we leave this enabled. It costs nothing and keeps a genuine safety feature working.
