Powertrain Control Module (PCM)
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The PCM is responsible for allowing starter and fuel injector operation. The PCM receives an enable or disable message from the BCM over the HS-CAN .
If the PCM is replaced, the parameter reset procedure must be performed to enable PATS .
