SPN558 FMI13
Accelerator Pedal or Lever Idle Validation Switch Circuit - Out of Calibration
CODES:
Fault Code: 432
PID(P), SID(S): S230
SPN: 558
FMI: 13/13
Lamp: Red
REASON: Voltage at idle validation on-idle and off-idle circuit does not match accelerator pedal position.
EFFECT: Engine will only idle.
Circuit Description:
The accelerator pedal or lever idle validation switch is used by the electronic control module (ECM) to indicate when the accelerator pedal is released (on-idle) or depressed (off-idle). The switch is adjusted at the factory to switch from on-idle to off-idle at the correct accelerator pedal position. The idle validation switch return is a shared return with other original equipment manufacturer (OEM) cab switches.
Component Location:
The accelerator pedal or lever position sensor is mounted to the accelerator pedal assembly. Refer to the OEM service manual.
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running.
Conditions for Setting the Fault Codes:
The Engine Control Module (ECM) detected the accelerator pedal or lever position and idle validation switch did not match.
Action Taken When the Fault Code is Active:
• The ECM illuminates the amber CHECK ENGINE lamp and/or the malfunction indicator lamp (MIL) 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.
Shop Talk:
This fault is logged when both the on-idle and off-idle validation switches disagree with the accelerator pedal or lever position signal. Turning the keyswitch ON while partially depressing the accelerator pedal or lever can cause this fault code to go active. This fault code will stay active until the pedal or lever is cycled through its full travel.
