SPN 558 - FMI 13 (Fault Code: 432)
SPN558 FMI13
CODES:
Fault Code: 432
PID(P), SID(S): S230
SPN: 558
FMI: 13/13
Lamp: RED
SRT:
REASON: Accelerator Pedal or Lever Idle Validation Circuit - Out of Calibration. 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 position sensor is attached to the accelerator pedal or lever. The accelerator pedal or lever position sensor sends a signal to the electronic control module (ECM) when the accelerator pedal or lever is depressed and released. The accelerator pedal or lever position circuit contains three wires: accelerator pedal or lever position supply, accelerator pedal or lever position return, and accelerator pedal or lever position signal. The switch return circuit for the on-idle and off-idle validation circuit is a shared return with other original equipment manufacturer (OEM) switches.
Component Location:
The accelerator pedal or lever position sensor is located on the accelerator pedal or lever.
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the keyswitch is in the ON position.
Conditions for Setting the Fault Codes:
The ECM detects that the position of the throttle pedal position and the idle validation switch do not match.
Action Taken When the Fault Code is Active:
• The ECM illuminates the red STOP ENGINE light immediately when the diagnostic runs and fails.
Conditions for Clearing the Fault Code:
The ECM will turn off the red STOP ENGINE light immediately after the diagnostic runs and passes.
Shop Talk:
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
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 will stay active until the pedal or lever is cycled through its full travel.
