Service Publications
Descriptions of Service Publications
Daimler Truck North America (DTNA) LLC distributes the following major service publications in paper and electronic formats. Refer to DTNA TechLit for more information.
Workshop/Service Manual
Workshop and service manuals contain service and repair information for all vehicle systems and components, except for major components such as engines, transmissions, and rear axles. Each workshop and service manual section is divided into subjects that can include general information, principles of operation, removal, disassembly, assembly, installation, and specifications. Workshop and service manuals contain service and repair information for all vehicle systems and components installed in our plants.
Maintenance Manual
Maintenance manuals contain routine maintenance procedures and intervals for vehicle components and systems. They have information such as lubrication procedures and tables, fluid replacement procedures, fluid capacities, and specifications. Maintenance manuals do not contain detailed repair or service information. Maintenance manuals should not be used for covering plant quality or quality assurance issues. The purpose of maintenance manuals is to increase the life of the component being maintained. Except for federally required maintenance items, like mufflers, these are recommendations, not requirements.
Troubleshooting Manual
Troubleshooting manuals contain diagnostic procedures for determining the root cause of fault codes and symptoms in vehicle components and systems, including multiplexed systems. In addition to fault codes and symptoms, testing procedures and ‘how to’ sections are included in troubleshooting manuals. The troubleshooting manual does not include information on the removal, inspection, or installation of components.
Technical Service Bulletins (TSBs)
TSBs provide issue notifications to the service network. They are intended for issues that can be addressed when the expected symptom or failure is present when the vehicle arrives in the shop for normal service. TSBs should not be used to bring a vehicle in for inspection, or update a vehicle before a failure has occurred. In the literature request system, they have a higher priority than Workshop, Drivers, and Maintenance Manuals. All TSBs must have a clearly defined symptom or customer complaint that is causing the customer to bring the vehicle into the dealership. If they do not, dealerships will take it as an expectation that they should be proactively checking every single vehicle when they come in. TSBs are not visible to vehicle owners and operators.
Parts Bulletin (PB) or Parts Technical Bulletin (PTB)
PBs are used to communicate information on parts. These bulletins contain lists of parts and Bills of Material (BOMs) needed to do replacement and upgrade procedures. PBs do not contain service procedures or Standard Repair Times (SRTs).
Customer Service Announcements (CSAs)
CSAs are used to communicate information to the dealer or distributor network. They remain on DTNA Portal and continue to be communicated via myComm.
Tool Letters (TLs)
TLs are used to communicate the release of both physical and electronic tools. They remain on DTNA Portal and continue to be communicated via myComm.
18SP Letters
18SPs are special procedures or instructions that are included in unique service parts kits. They are available on TechLit in the event that someone lost their kit’s original copy.
Original Equipment Manufacturer (OEM) Letters
OEM letters are other suppliers’ letters that we make available on TechLit as a courtesy.
DTNA Portal
Service and parts applications and information can be accessed on the DTNA Portal. While there is some content available to users without logging in, access to most content and applications on DTNA Portal requires authentication by registered users. Registration requirements for each user type can be found on the main landing page before logging in. In addition to accessing Aftermarket applications, DTNA Portal can be used for searching all content published within DTNA Portal pages as well as within many applications. The following applications can be accessed via DTNA Portal.
TechLit
Web-based service manuals can be accessed on the TechLit application.
PartsProX
PartsProX® is an electronic parts catalog system, showing the specified vehicle's build record.
EZWiring
EZWiring™ makes products' wiring drawings and floating pin lists available online for viewing and printing. EZWiring can also be accessed from within PartsProX.
Service Solutions
The Service Solutions application provides diagnostic assistance with Symptoms Search, by connecting to a large knowledge base gathered from technicians and service personnel. Solutions published within Service Solutions are routed through DTNA Compliance, but are not vetted through the normal reviews that service bulletins, service manuals, and campaigns go through. Content published should only be published on Service Solutions if it doesn’t meet the criteria to be published in one of the more official publication types.
Vehicle Info
Vehicle Information is a single point of entry to search for DTNA and Detroit Diesel service information. This allows you to search for information specific to a vehicle or Detroit Diesel engine. Vehicle specifications, vehicle recalls and campaigns, warranty information, and vehicle literature can all be found within Vehicle Info. It also contains the registration information for the selected vehicle.
Warranty Lit
Review important warranty information including warranty manuals, letters, recall and field service information and more.
Recall Campaigns
Recall campaigns cover situations that involve service work or replacement of parts in connection with a recall notice. These campaigns pertain to matters of vehicle safety. All recall campaigns are distributed to dealers; customers receive notices that apply to their vehicles.
Field Service Campaigns
Field service campaigns are concerned with non-safety-related service work or replacement of parts. All field service campaigns are distributed to dealers; customers receive notices that apply to their vehicles.
Warranty Manual
This manual covers the provisions and procedures under which authorized service facilities will be reimbursed for warranty-related work on products, parts, and accessories manufactured or supplied by DTNA.
