| U0109 | Lost Communication With Fuel Pump Control Module | The PCM monitors the fuel pump monitor (FPM) circuit for the presence of a duty cycled signal. If the FPM circuit is fixed at a low or high-voltage, the PCM begins to increment a counter.

| U0300 | Internal Control Module Software Incompatibility | This DTC indicates there are incompatible software levels within the PCM that control the electronic throttle control (ETC) system.

The microprocessors must have the correct level of software in order to communicate and function together. | See POWERTRAIN CONTROL MODULE (PCM) MALFUNCTION . |
| U210B | Lost Communication Between Fuel Pump Control Module and Restraints Control Module | The fuel pump control module monitors the duty cycle and frequency of the signal it receives from the restraints control module (RCM), The fuel pump control module determines if the signal on the event notification signal (ENS) circuit from the RCM is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module sends a 40% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM. The test fails when the fuel pump control module is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time. | See FUEL PUMP (FP) PRIMARY OR SECONDARY CIRCUIT . |
