Subject File: Engine
Subject: MaxxForce® 13 Electronic Control Module (ECM) and Aftertreatment Control Module (ACM)
Recalibration and Aftertreatment Fuel Line 1 Replacement for Certain Vehicles Marked in Service PortalSM with
AFC 13918 to Provide Protection Against Damage to Fuel Shut-Off Valve (FSOV) Pressure Sensor.
Model: PayStar®, ProStar®, TranStar®, and WorkStar®
Start Date: 04 March 2013 End Date: 07 August 2013
Engine Family: N13 (EPA 10) with SCR

DESCRIPTION
Certain MaxxForce® 13 engines may experience damage to Fuel Shut-Off Valve (FSOV) pressure sensor if
the aftertreatment fuel line is not replaced prior to reprogramming the ECM and ACM. To prevent damage
to FSOV pressure sensor, this procedure will require replacement of the solid aftertreatment fuel line 1 to a
new aftertreatment fuel line 1 with a flexible section and recalibration of both the engine Electronic Control
Module (ECM) and Aftertreatment Control Module (ACM). This procedure is applicable only to certain vehicles
marked in Service PortalSM with AFC 13918.

SERVICE PROCEDURE
WARNING: Park vehicle on hard flat surface, turn engine off, set parking brake, and install
wheel chocks to prevent vehicle from moving in both directions. Failure to do so may result in
property damage, personal injury, and / or death.

WARNING: If vehicle must be raised, do not work under vehicle supported only by jacks.
Jacks can slip or fall over, potentially resulting in property damage, personal injury, and / or death.

WARNING: Always wear safe eye protection when performing vehicle maintenance. Failure
to do so may result in personal injury and / or death.

WARNING: Keep flames or sparks away from vehicle and do not smoke while servicing
the vehicle’s batteries. Batteries expel explosive gases. Failure to do so may result in property
damage, personal injury, and / or death.

WARNING: Remove ground cable from negative terminal of battery box before disconnecting
any electrical components. Always connect ground cable last. Failure to do so may result in
property damage, personal injury, and / or death.

NOTE: Perform replacement of Hydrocarbon Injection (HCI) fuel line 1 before performing ECM
Recalibration.
1. Bring vehicle into shop and park on flat surface.
2. Turn wheels to right.
3. Shift transmission to Park or Neutral, set parking brake, and install wheel chocks.
4. Open battery box cover and disconnect negative battery cable from batteries.
5. Unlatch and open hood.
6. Unlatch and flip front bumper down, if equipped.

ECM / ACM RECALIBRATION
NOTE: Perform replacement of Hydrocarbon Injection (HCI) fuel line 1 before performing ECM
Recalibration.
1. Check to see if ECM has latest software by referring to vehicle calibration scorecard in Service PortalSM
system. If calibration scorecard indicates that calibration is not current, engine must be reprogrammed to
raise calibration to latest level.
NOTE: The below articles contain general information about each reprogramming method and software,
with links to specific instructions for each.
NOTE: If AutoUpgrade functionality is not available, use NETS.
2. Program ECM using NETS or AutoUpgrade. For instructions, see IK2600010 - NETS Programming and
Troubleshooting Guide. Use most current Update to Latest Calibration programming option or follow
IK2600082 – Auto Upgrade Programming Instructions.
3. If assistance is needed, contact Vehicle Programming by creating an iKNow case file or calling
1-800-336-4500, options, 3, 1, 1.
4. Run diagnostic check. If no fault codes or leaks are present, procedure has been completed.
5. Remove wheel chocks.
