IC Bus Diagnostic Scan Tool
IC Bus, formerly known as IC Corporation, is an American manufacturer and a wholly-owned subsidiary of International Motors. The company currently produces school buses and commercial-use buses used in multiple applications.
The IC name stands for “Integrated Coach” and is a description of how the buses are manufactured. The unique USP of the company is that the vehicles are assembled under a single corporate structure. The body and the chassis are matched in the same facility, and the hood is shared with International-brand trucks.
If you have a fleet of IC International buses or have a service center, the Jaltest IC bus diagnostic scan tool is essential for you. It offers comprehensive diagnostics and maintenance solutions for International IC buses.
When a fault code pops up on the display panel of the onboard computer of the vehicle, simply connect our Jaltest IC bus diagnostic tool for cutting-edge fault code reading, analysis, and clearance. Any minor malfunction will be quickly resolved before it becomes a major problem.
Our Jaltest IC bus diagnostic code scanner offers a wide range of technical information that allows you to quickly locate the fault, resolve it, and get your bus back on the road at the earliest. Access the software and get all technical information about the vehicle, including engine specifications, capacities, and wiring diagrams of systems and components.
Apart from the IC bus diagnostic software, our Jaltest maintenance tool covers other critical machines like construction equipment, agricultural equipment, material handling equipment, trucks, marine engines, and others.

Extensive Coverage Across IC Bus Models
When you invest in the Jaltest IC bus fault code reader, you are assured of smart diagnostics for school and commercial IC buses across North America and Canada. You get advanced repairs and diagnostic support across your entire fleet of IC International buses, even if you have a mixed fleet of various models. Among the top IC Bus Series covered by the Jaltest software are:
- CE Series (School/Commercial)
- RE Series (Rear Engine Transit)
- BE Series (Smaller School Bus)
- HC Series (High Capacity)
The advantage of using the Jaltest IC bus diagnostic scanner is that it is a one-stop fault resolution solution for all leading models of IC buses. You do not have to invest separately in an IC CE bus diagnostic scan tool or an IC RE bus diagnostic software; one Jaltest IC diagnostic scanner is good across the entire range.

Diagnostic Solutions Across Body Modules
When you invest in the Jaltest IC bus diagnostic scanner software, you get comprehensive coverage, support, and solutions for all body modules, components, and systems. These include Multiplexing Systems, HVAC Control Module, Instrument Cluster, Lighting Systems, Doors & Safety Systems, ABS/ESC Units, and more.
The Jaltest tool connects automatically to these systems in IC buses, enabling you to get in-depth coverage of faults on-premises without needing to wait for service engineers.
With our software, you can carry out preventive maintenance activities or troubleshoot by symptoms. In the first case, you carry out periodical full system scans so that any issue is located and resolved before it acquires a level that would require downtime. This activity helps to keep your buses in peak running condition.

- HVAC Control Module
- Instrument Cluster
- Lighting Systems
- Doors & Safety Systems
- ABS/ESC Units
On the other hand, whenever a fault occurs, the software will troubleshoot that specific issue and resolve it at the earliest.

Fault Resolutions of Engines and Transmissions
IC International buses are assembled in one facility, and the engines and transmissions are sourced from different manufacturers. Here are the main engine and transmission models used in IC buses.
Engines :
- Cummins ISB 6.7
- Cummins ISL 9
- Navistar MaxxForce DT
- Navistar MaxxForce 7
- Navistar N9/N10
- Cummins B6.7
Transmissions :
- Allison 2000/2500/3000/4000 Series
- Eaton Ultrashift (select models)
The engines and transmissions used in IC buses are sourced from leading manufacturers in the world and contribute to the reliability of IC buses.
Among the most critical activities carried out by the Jaltest IC bus engine diagnostic software is forced regens for diesel engines. When the Diesel Particulate Filter (DPF) is blocked with soot, the performance of the vehicle goes down. Our diagnostic software will help you navigate the process to clear the DPF so that your bus is again performing optimally.
Forced regen is a very complex activity that is effortlessly done by the Jaltest software.

Optimized Troubleshooting By IC Bus Diagnostic Tool
Various activities are carried out by the Jaltest IC International diagnostic software. Among the special functions possible are cylinder cut-out tests, DPF regeneration, and injector coding based on the bus model and system. Moreover, the software displays real-time sensor data from the vehicle’s system that enables easy monitoring and troubleshooting.
Most importantly, you can read, analyze, and clear fault codes stored in the Electronic Control Units (ECUs) in the vehicle. Any fault code is analyzed and interpreted, after which the software navigates to solutions that are no less than what is offered at the dealer level.
The Jaltest IC bus fault code scanner software is updated three times every year. This is to keep the software in sync with any technological innovations that might be introduced in IC buses.
