Fuel Injection Pump
This code is generated when fuel injection pump does not receive a
position signal or signal received by fuel injection pump is incorrect.
Signal Abnormal.
ECM will log diagnostic code. Fuel injection pump will use engine
speed/timing sensor in order to set engine timing. ECM will derate rpm
by 20 percent. Engine will also experience any of these conditions: low
power or a reduction of power, increased emissions, and hard starting.
1684 09
Fuel Injection Pump Not This code is generated when fuel injection pump detects a failure of
Communicating on Link. CAN data link, ECM sent incorrect data, or fuel injection pump sent
incorrect data. ECM will log diagnostic code. ECM will cause fuel
injection pump to stop injection of fuel. When this code is generated,
ECM shuts down engine and will not allow it to restart.

connectors are incorrect. ECM will log diagnostic code. ECM will
derate engine speed by 20 percent. Engine may experience low power
and reduced speed while diagnostic code remains active.

will derate engine speed by 20 percent. While diagnostic code is active,
engine will experience low power and reduced speed.
1684 14
Fuel Injection Pump.
This code is generated when ECM detects a communication failure with
fuel injection pump. Communication failure may be due to
disconnected connectors for fuel injection pump or a faulty wiring
harness for fuel injection pump. ECM will log diagnostic code. This
diagnostic code will have no effect on engine performance. Code 1684-
14 is normally accompanied by 174-02 or 320-02. Code 174-02 may
cause engine to have low power. If 320-02 is active, ECM will limit
engine to 1,200 rpm.
