Vehicle report
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 document is intended to inform dealers, technicians, parts departments, and customers of a change made to radio software to support updated Collision Mitigation, Lane Departure Warning (LDW), and Blind Spot Monitoring systems. If replacing the radios on the vehicles described below, the radio either needs to be built after a specific build date or have the software version verified/updated. If outdated radio software is used on these vehicles, the audible tones for these systems may not be heard by the driver. The applicable vehicles were all built with the correct radio. This iKNnow article only applies if replacing the radio for a service event in one of the vehicles listed below.

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. This article lists currently available winter front covers that can be installed on the front grille and bumper to reduce cold air flow to the engine compartment.

In some instances, the driver's or passenger's door pod may become unresponsive, where it will not respond to any manual inputs from the driver or passenger. 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 document reminds technicians of the critical relationship between the truck's suspension and the driveline operating angles. The information applies to diesel, gas, and electric vehicles.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
