Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

This article only applies to Models w/ 0016UZL Built Between 06/23/2014 – 05/11/2020 OR Models w/ 0016UZL w/ Safety Recall 14516 Completed Reference the appropriate Technician Manual for models outside of this population. Safety Recall 14516 has been issued for units built before June 23, 2014. For LT and 2018+ LoneStar: If there is a complaint of the bunk blower turning off after an auto start event, the BCM needs to be updated to Data Version 323 or higher. • The bunk blower turning off was only present in BCM Data Version 309 to Data Version 322 To properly diagnose the system, you must ensure the recall has been performed. Only the "Cold Loop" sealed refrigerant core PN # 2614669C1 is to be replaced when the refrigerant circuit fails. DO NOT REPLACE THE COMPLETE UNIT IF THE A/C IS NOT FUNCTIONING. Complete unit is not Warrantable Refer to the BASIC TROUBLESHOOTING below before replacing any components. This will help you identify which component is at fault or any electrical issues. Refer to PARTS INFORMATION to properly identify the parts that may require replacement The A/C portion of the system is listed below in the parts section. The 16UZL No-Idle HVAC system is designed to disengage when the engine is started, and can be turned on with the key in any position. This battery-powered no-idle HVAC system provides heating and cooling of the sleeper area without use of the vehicle engine. The system is comprised of the no-idle HVAC components located in the sleeper HVAC module, a separate fuel-operated coolant heater mounted under the sleeper, and four additional batteries housed in a second battery box. The no-idle HVAC system shares the air handling assembly and several major components with the truck's standard HVAC system. Most importantly, the shared evaporator core contains refrigerant circuits for both the no idle system and the truck's standard A/C system. With this configuration, some procedures required to service the no idle A/C system will require opening the refrigerant circuit of the truck's standard A/C system. Trucks equipped with the 16UZL No-Idle HVAC system have two separate HVAC systems (Standard Truck A/C and the MaxxPower unit); it is important to identify each clearly, so you are troubleshooting the correct system. Per the Operator's Manual page 10: Run the heater at least once a month during the year (for a minimum of 15 minutes).

This tool is designed to compare Diamond Logic feature data across multiple vehicle configuration files. It allows users to quickly load files either manually or directly from the Diamond Logic Builder Vehicles folder using VIN-based selection. As files are added or removed, the comparison runs automatically with no manual action required. The program presents results in an interactive table that shows feature codes, descriptions, access levels, and whether each feature is present in each selected file. Built-in search, filtering, and sorting make it easy to locate specific features or focus only on differences between files. Column visibility can be customized to show or hide descriptions and access information as needed. Users can remove files individually or clear all files at once, with results updating instantly. The tool also includes reporting and export options that reflect exactly what is visible on screen, allowing results to be printed, copied, saved as text, or exported to CSV for use in Excel or other spreadsheet tools. Overall, the program streamlines the process of comparing vehicle feature configurations, helping users quickly identify differences, validate setups, and document results without manual comparison or external tools.

In some geographic areas, ambient temperatures reaching below 40°F (4°C), including high levels of humidity, an operator may experience engine stalling, low performance, and/or poor aftertreatment performance. This is caused by condensation accumulating and freezing within the Charge Air Cooler (CAC); affecting air flow into the engine.

In some of these situations, it is possible for this symptom to be present without any fault codes becoming active. This article will guide the user through performing a hard reset of a door pod, which can restore the door pod to its operational condition, thereby avoiding the need for replacement. The steps in this article should be performed BEFORE diagnostics are completed for any active faults.

This document is to notify the field of an issue with BCM that causes various electrical system concerns after the vehicle sits for 2-3 days. This can affect all LT, RH, MV, HV models, 2021MY and up HX, 2024MY and up CE Bus with BCM kernel version 752, 753, and 754. Vehicles built or updated with DLB between 6/1/25 and 11/4/25 are suspected of having these kernels installed on the BCM. The most common complaint is that the steering wheel switches do not function, which, depending on the vehicle model and options, can cause the bus door, pupil warning lights, radio controls, marker interrupt, and cruise control to stop working. Other complaints can include short circuit faults from multiple sensor circuits attached to the BCM setting at the same time, the vehicle will not go into gear, the headlights are stuck on, the brake lights are stuck on, or the parking brake alarm is sounding (horn chirping) with the parking brake set. As of 11/4/25, these symptoms can be resolved by updating the BCM to kernel 755 or later with DLB.

This action addressed the Diesel Exhaust Fluid (DEF) Quality Sensor failures in the field and the unavailability of parts due to the worldwide chip shortage. This recall is step two of this program designed to revert all affected vehicles back to the certified calibration and to provide them with the latest improved DQS and Coolant Control Valve (CCV) designs. Additionally, the emergency calibration and the restoration to the certified calibration with the latest improved DQS and Coolant Control Valve (CCV) designs have no effect on vehicle Emissions.

The Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have approved an emergency calibration to provide temporary relief from the global supply shortage of electrical components. When there is a communication fault in the DEF head unit / Quality Level Sensor (QLS) this temporary calibration will allow the vehicle to operate. The procedure in this document will include diagnosing the DEF head unit / QLS and if found to be defective will advise to install the temporary engine calibration if replacement parts are not available. Any vehicle that receives this calibration will be required to have it removed and a new QLS installed once parts become available, this will be managed through future communication.
