#Ford ids system code

The PATS control module in the PCM provides ground to the starter relay and enables the fuel pump and injectors. The PATS control module built into the PCM. The PATS control module is a standalone module located behind the dash on the left side. The PATS control module is NOT a standalone module. Must have two programmed keys in the control module to allow vehicle starting.

If the key code is valid, the PATS control module also grounds the control coil in the starter relay, which moves the contacts and sends power to the starter motor solenoid PATS System B Some vehicles also include a starter relay. The PCM then allow the fuel pump and injectors. If it is, the control module sends a validation signal to the PCM via the Vehicle Communication Network (SCP). Within that 1 second period, the PATS Control Module must determines if the key code is valid. The transceiver sends the key code signal via a hardwired connection to the control module.Īt each start sequence, the PCM power the fuel pump and injectors until the engine runs for 1 second. Only 1 key needs to be programmed for the system to work. When you turn the key to RUN/START, the theft warning light turns on for 2-seconds.

The PATS control is a stand alone module.

non-encoded key (key has no electronics).

These faults will disable the vehicle from starting If the key code does not prove out or there is a fault with the system, the PATS warning light will either stay light or flash. If the key code is correct, the PATS control module sends a signal to the PCM to enable the fuel pump and injectors.ĭuring this period, the PATS security warning light is illuminated. The PATS control module compares the received key code and validates or rejects the key code. The key code data is stored in the PATS control module. The transceiver sends the key code to the control module through the receive Rx signal. The PATS transceiver receives data from the control module through the transmit Tx signal. The transceiver energizes the transponder key electronics through the key’s circular antenna. The PATS transceiver is mounted on the ignition lock cylinder housing and is connected to the PATS control module. As you turn the key to the RUN or START position, the PATS control module initiates the key interrogation routine.
