PACCAR PX-8 CM2150 (2007-09) Fault Code: 2777 PID: 390 SPN: 3703 FMI: 11 Particulate Trap Active Regeneration Inhibited Due to Permit Switch – Condition Exists.
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 this fault code is active and there has been damage to the aftertreatment system, the permit switch may have prevented the aftertreatment system from performing a mobile (active) regeneration. Consult with the OEM if the aftertreatment system has failed due to the permit switch.
Possible repairs:
1)If necessary, recalibrate the ECM.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2765 PID: SPN: 2797 FMI: 13 Engine Injector Bank 1 Barcodes – Out of Calibration. Invalid injector barcode information has been entered.
