QSK60G CM2358 Engine Remote Accelerator Will Not Operate Solution

This instruction show you guide on how to solve Cummings QSK60G CM2358 engine remote accelerator can not work.

QSK60G CM2358 Engine Remote Accelerator Will Not Operate Solution

 

Reason:

Low voltage detected at remote accelerator position signal circuit.

Remote Accelerator Pedal or Lever Position Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source

 

What You Need?

Cummings Insite 8.9.2

Cummings inline6 diagnostic adapter

 

Circuit Description

The remote accelerator position sensor is a potentiometer attached to the remote accelerator lever. The remote accelerator position sensor varies the signal voltage to the engine control module (ECM) as the remote accelerator lever is depressed and released. Low signal voltage is received by the ECM when the remote accelerator lever is at 0 percent. A high signal voltage is received by the ECM when the remote accelerator is at 100 percent. The remote accelerator pedal position circuit contains a remote accelerator pedal position 5 volt supply, remote accelerator pedal position return, and remote accelerator pedal position signal.

 

Component Location

The remote accelerator pedal or lever location varies with each original equipment manufacturer (OEM). Refer to the OEM service manual.

 

Conditions for Running the Diagnostics

This diagnostic runs continuously when the keyswitch is in the ON position.

 

Conditions for Setting the Fault Codes

The Engine Control Module (ECM) detected the remote accelerator pedal signal voltage was out of range low.

 

Action Taken When the Fault Code is Active

The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.

 

Conditions for Clearing the Fault Code

To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute.

The fault code status displayed by the recommended Cummins® electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.

The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.

The “Reset All Faults” command in the recommended Cummins® electronic service tool or equivalent can be used to clear active and inactive faults.
