Diagnostic Codes Table
Code and Description Conditions which Generate this Code System Response
1627-5 Fuel Pump Relay current below normal The engine's Electronic Control Module (ECM) detects an open circuit at the fuel pump relay for 60 seconds.
The ECM detects a short to battery voltage for the fuel pump relay for 60 seconds.
The ECM can only detect this condition when the output driver is not activated. The code is logged.
1627-6 Fuel Pump Relay current above normal The engine's ECM detects a short circuit for the fuel pump relay.
The ECM can only detect this condition when the output driver is activated. The ECM has the ability to energize the fuel pump relay. The fuel pump relay controls battery power to the fuel priming pump.ECM Activation of the Fuel Priming PumpThis strategy improves the capability of the fuel system at low engine speeds.The ECM will automatically activate the fuel priming pump while the engine state is CRANKING, RUNNING, or POSTRUN. The ECM deactivates the fuel pump when the engine speed is greater than 200 rpm. Manual Override of the Fuel Priming PumpA "Fuel Priming Pump Command Override" that is in Caterpillar Electronic Technician (ET) can be used to diagnose the circuit that is for the electric fuel priming pump. A "Fuel Priming Pump Command" parameter is also available in Cat ET that can be used to view the status of the ECM output.When the override is activated, the ECM powers the electric fuel priming pump. The ECM will command the throttle position to 25 percent. This provides a path for air to escape from the low pressure fuel system. To use this feature, the ECM and the keyswitch relay must be powered. Also, the engine speed must be 0 rpm.
