After replacement of any TRON module, the gateway module (GWM) and the TRON capable modules can set diagnostic trouble codes (DTCs) U211A, U211B, U211C, U3034, U3035, U3036, U35D9, U35DA and/or U35DB if the secret authentication security keys are not aligned between the modules, a loss of communication is occurring between modules and/or a module is not responding. This may be a result of missing the new module secret authentication security key obtained when running the Ford Diagnosis and Repair System (FDRS) "Trusted Real-Time Operation Network (TRON) Module Authentication" procedure after replacement. When replacing a TRON capable module, run the FDRS "Trusted Real-Time Operation Network (TRON) Module Authentication" procedure in the GWM tool box, not in the toolbox of the module with…

Some 2023 F-Super Duty vehicles equipped with a 6.8L or 7.3L engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P061B, U0140, U3035 and/or U3036 stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.

Some 2023 F-Super Duty vehicles may set diagnostic trouble codes (DTCS) U3035 and/or U3036 in the powertrain control module (PCM) during a diagnostic self-test. These DTCS set when the PCM detects an authentication failure after key initialization (U3035) and/or while the PCM continues to monitor DTC (U3036) during the transition of the controller area network (CAN) bus entering sleep mode. U3035 and/or U3036 should be ignored if: no other DTCs are present in the PCM, the malfunction indicator lamp (MIL) is not illuminated while the engine is running, and no drivability concerns are present. No further service action is required.
