Applies To: $13 Integrated (S13 Engine, T14 Transmission & Aftertreatment)

CHANGE LOG

Please refer to the change log text box below for recent changes to this article:

09/04/2025 - Added RC6 Calibration Changes
104/07/2025 - Added RC5 Calibration Changes
01/29/2025 - Added RC4 Calibration Release
109/23/2024 - Initial Article Release

DESCRIPTION

This article will provide the calibration revision history for $13 Integrated EPA 2024 Powertrains.

NOTE: Calibrations will update to the most recently released calibration. The latest calibration content will include all previously
released calibration content.

NOTE: International utilizes campaigns and diagnostics to assess the necessity of calibration updates. Warranty claims may be
denied if there is no active campaign or if diagnostics do not indicate that a calibration update is required.”

Calibration Update Advisory:

e After a TCM calibration update, the vehicle may lose its Initial Vehicle Movement response ("Urge to Move"). To resolve
this, use SDS: TCM > Procedures > Reset: Accelerometer Adaption and click Reset.

Current Calibration Release

High Level Overview of the "RC6" Calibration Release

e Misfire: SPN 1322 through 1328 FMI 31 (Reduction of codes logging under false pretenses (resolves issue in a small
population))

Driver Rewards: Prevent Reset during key cycle

Fault Codes: 5835 FMI 9, 7030 FMI 9, SPN 105 FMI 20, SPN 110 FMI 20, SPN 175 FMI 20, SPN 157 FMI 18

Brake Switch Faults: Corrected fault codes were not being detected when a brake switch had failed

High Soot Load Reaction (SPN 3251/0): Reaction changed from when the vehicle is moving and not moving

High Level Overview of the "RC5" Calibration Release

Fuel Analytics: enhancements for On Command Connection Reporting
Regeneration: Updates to increase Performance

SDS Change: Fix for fan turning on when running service diagnostic tests
Codes: SPN 157 FMI 18, SPN 2067 FMI 9, and SPN 91 FMI 19
PTO: TSC1 messaging updates
Accumulators: Several accumulator changes
Transmission: (SPN 2607 FMI 9) Prevent Electronic Clutch Actuator Bricking Failures (Tow Event)

High Level Overview of the "RC4" Calibration Release

$13 Codes SPN 110, 105 & 175 FMI 20: Logging due to coolant heating with the engine not running.
Regeneration: Allow regeneration when Auto Start Stop is used for extended periods.

Hydrocarbon Desorb: Improvements implemented.

Compression Break: Improvements implemented.

Park Regeneration: Enhancements made.

DEF Line Freezing Protection: Upgrades introduced.

Additional Enhancements: Multiple other improvements are detailed below

High Level Overview of the "RC3" Calibration Release

Optimization of 50+ Diagnostic Trouble Codes (DTCs): Reduced false positive faults and related dash lights &
messages.
e Note: All related GUIDE Live Diagnostic Procedures now direct technicians to update the calibration. Additional
diagnostics are available if a code continues to set
Engine Fan Activation: During hot ambient temperature conditions in PTO mode to prevent PM Sensor overheating.
Compression Release Brake (CRB): Minimum engine speed for activation.
DEF Level Reading: Corrected the issue where the DEF level reads “O” after flashing.
Fuel Economy Reporting: Improved accuracy.
Additional Enhancements: Multiple other improvements are detailed below

Specific Details of the "RC6" Calibration Release
Fuel Analytics Updates.

RC6 Calibration Released on 09/XX/2025

MRC 24A33 and 24A34 to update calibration on trucks with S13 engines

Perform MRC to get latest updates

ECM Software ID: SxxxCMKA

SPN 1322 thru 1328 FMI 31 |/Reduction of codes logging under false pretenses (resolves the issue in a small population).

Corrected brake switch faults are not being detected when a brake switch has failed.

SPN 5835 FMI 9 Prevent code from logging under false pretenses.

SPN 7030 FMI 9 Prevent code from logging under false pretenses.

Engine fan operating state changes.

Injector adaptation values can now be read/write with DID.

Accumulator improvements

Long term solution to reduce the occurrence of false plausibility fault codes caused by engine
coolant circulation and heating when the engine is not running. This applies to trucks equipped
with aftermarket ESPAR heaters, Auxiliary Power Units (APU) integrated into the factory
coolant system, and trucks built with feature Code 16UZL (No Idle A/C by Bergstrom).

SPN 105 FMI 20
SPN 110 FMI 20
SPN 175 FMI 20

SPN 157 FMI 18 Monitor improvements to detect failure earlier.

The Split Shaft vehicle speed signal comes from the front axle speed signal.

ECM to honor TSC1 speed control request from body builder module when PIM signals on
CAN interlocks are met.

ECM reports that the source address is controlling the engine when the TSC1 source address
is in control of the engine.

FON seeding to support injector adaptation at manufacturing.

Boost monitor improvement for over, under boost, and slow response.

Turbocharger speed signal improvements.

Soot model fix when operating in SCR warmup mode.

Reaction change: When the vehicle is moving, change the 30-second delayed shutdown to no
SPN 3251 FMI 0 regeneration allowed. When the vehicle is NOT moving, change 30 second delayed shutdown
to an immediate shutdown.

\|Key on plausibility change for coolant and oil temp sensors.
