P07EC	Transmission Range Multi-Function Select Circuit	The GSM contains 3 contacts beneath each button. If one contact is not recognized by the GSM then DTC P07EC sets. If two Brake Transmission Shift Interlock (BTSI) override switch inputs do not change state, P07EC may set. A message is displayed on the message center warning that a given range is unavailable. If Reverse or Neutral are unavailable, the vehicle is placed in Park when the vehicle stops moving. If Park is unavailable, the vehicle automatically shifts to Park when the vehicle stops moving. If Drive or Sport is unavailable, the operator is prompted to use the other forward gear. CLEAR the DTC. PERFORM the GSM self-test. If the DTC returns, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
P07ED	Transmission Range Multi-Function Select Circuit Stuck	The GSM contains 3 contacts beneath each button. If two or more contacts are not recognized by the GSM then DTC P07ED sets. If two Brake Transmission Shift Interlock (BTSI) override switch inputs do not change state, P07ED may set. A message is displayed on the message center warning that a given range is unavailable. If Park is unavailable and Reverse, Drive or Sport is selected, the vehicle automatically shifts to Park when the vehicle stops moving. If Reverse is unavailable and Drive or Sport is selected, the vehicle automatically shifts to Park when the vehicle stops moving. If Neutral is unavailable and Reverse, Drive or Sport is selected, the vehicle automatically shifts to Park when the vehicle stops moving. If Drive is unavailable and Reverse is selected, the vehicle automatically shifts to Park when the vehicle stops moving. The operator is prompted to select Drive or Sport to get Drive. If Sport is unavailable and Reverse is selected, the vehicle automatically shifts to Park when the vehicle stops moving. CLEAR the DTC. PERFORM the GSM self-test. If the DTC returns, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
P07F2	Transmission Range Control Module Communication Circuit	GO to Pinpoint Test C
P07F3	Transmission Range Control Module Communication Circuit Low	GO to Pinpoint Test C
P07F4	Transmission Range Control Module Communication Circuit High	GO to Pinpoint Test C
P081F	Brake Transmission Shift Interlock (BTSI) Signal Correlation	GO to Pinpoint Test D
P164E	Internal Control Module Transmission Range Performance	Transmission may not shift from Park with a flashing P button. The EPB is applied without operator request. CLEAR the DTC. REPROGRAM the original GSM with the latest software. PERFORM the GSM self-test. If the DTC returns, INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
P166B	Drivers Door Status Correlation	Open then close the drivers door and cycle the door locks. If the door ajar icon is illuminated on the IPC or the door lock and unlock is not working correctly, REFER to: Locks, Latches and Entry Systems . If the door ajar and locks are working correctly, GO to Pinpoint Test E

U0073	Control Module Communication Bus "A" Off	Park may be available only by door or seatbelt changing state. Stay In Neutral may be disabled. Neutral Tow may be disabled. Exit from Neutral Tow may be disabled. INSPECT the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals. CLEAR the DTC. PERFORM the Network Test. If the DTC returns, REFER to: Communications Network .
U0100	Lost Communication With ECM / PCM "A"	GO to Pinpoint Test I
U0121	Lost Communication With Anti-Lock Brake System (ABS) Control Module	GO to Pinpoint Test K
U0140	Lost Communication With Body Control Module	GO to Pinpoint Test L
U0151	Lost Communication With Restraints Control Module	GO to Pinpoint Test M
U0155	Lost Communication With Instrument Panel Cluster (IPC) Control Module	GO to Pinpoint Test N
U019E	Lost Communication With Transmission Range Control Module	If DTC P07F5, U101E and/or U101F are present, diagnose those DTCs first. PERFORM the Network Test. If DTC DTC U019E is the only DTC present, GO to Pinpoint Test O
U0301	Software Incompatibility with Engine/Powertrain Control Module	Transmission cannot exit Park. CLEAR the DTC. REPROGRAM the original PCM with the latest Lincoln PCM software. PERFORM the PCM self-test. If the DTC returns, Refer to PCM Guided Routine .
U0401	Invalid Data Received from ECM/PCM "A"	This DTC indicates the PCM is sending a fault message for one or more data signals the GSM uses for function. Using the diagnostic scan tool, CLEAR all DTCs. PERFORM a PCM self-test. If PCMDTCs are present, Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) . and follow the PCM repair procedures.
U0415	Invalid Data Received from Anti-Lock Brake System (ABS) Control Module	This DTC indicates the ABS module is sending a fault state for vehicle speed. Using the diagnostic scan tool, retrieve ABSDTCs. REFER to: Anti-Lock Brake System (ABS) and Stability Control . and follow the ABS repair procedures.
U0422	Invalid Data Received from Body Control Module	This DTC indicates the BCM is sending a fault state for one or more signals the GSM uses for function. Using the diagnostic scan tool, CLEAR all DTCs. PERFORM a BCM self-test. If BCMDTCs are present, REFER to: Body Control Module (BCM) . and follow the BCM repair procedures.
U0452	Invalid Data Received From Restraints Control Module	This DTC indicates the RCM is sending a fault state for the drivers seat belt. Using the diagnostic scan tool, CLEAR all DTCs. PERFORM a RCM self-test. If RCMDTCs are present, REFER to: Airbag Supplemental Restraint System (SRS) . and follow the RCM repair procedures.
U049F	Invalid Data Received From Transmission Range Control Module	This DTC indicates the PCM is able to receive TRCMCAN messages but the TRCM is indicating a fault on one or more of the data signals the GSM uses for function. Using the diagnostic scan tool, retrieve TRCMDTCs. REFER to TRCMDTC chart and follow the TRCM repair procedures.
