Jaltest Bus Diagnostic Tool

What's in the box

The case contains the hardware through which you establish the connection, plus the software right that unlocks the Bus module. The hardware is the same as in the separate set 70001052; the difference between the diagnostic devices lies in the software module, not in the case. Below you'll find what each component is and which reference number applies.

Hardware

• Jaltest Link V9 (70001015): The diagnostic interface you connect to the bus diagnostic socket, with 26-pin DB26 to the cable and USB-C to the PC.
• Multipin Kit (70002001): Twenty multipins JTP01 through JTP10, each in two colours, the connection cable JTP101 and two power cables — JDC10AM2 with battery clamps and JDC20AM2 for the cigarette lighter socket. This lets you connect directly to a connector for which no dedicated diagnostic cable exists.
• OBD cable, 16-pin (JDC213.9): The standard cable for the regular diagnostic socket.
• USB-C cable (JDC107.9B): The connection between the Link and your laptop.
• Extension cable, 100 cm (JDC100): With a 26-pin DB26 connector, the wide connector on the Link itself. Useful when the control unit is in a switch cabinet or at the rear of the bus.
• Case (70003015): The compact version, 505 × 381 × 146 mm.

Software

• Software (293300): The one-time purchase that unlocks the Modular Bus module. With Modular, the first year of use is included, so no separate software licence is needed.
• Jaltest GRP: The workshop software from Cojali for customers, vehicles and reports, in Basic, Synchro and Enterprise modes; these modes can be activated free of charge.

A laptop and the bus cables are not included. See Cables and computer further down on this page.

Which buses and systems does it cover

Jaltest Modular Bus covers city buses, regional coaches and touring coaches. A manufacturer in the list means there is coverage, not that every model and build year is fully supported. The division by continent refers to the country where the manufacturer originates, not the current owner.

Bus makes covered

Well-known manufacturers among the buses in Jaltest Modular Bus coverage: Irizar, Mercedes-Benz, Scania, Setra, Van Hool, VDL and Volvo.

All 73 bus manufacturers, divided by continent:

Europe includes the United Kingdom, Turkey, Russia and Belarus. Chinese is separate from Asian, which includes Japan, South Korea and India. Under Other are manufacturers from Australia and Africa.

Bus systems

• Powertrain: Engine, gearbox and exhaust aftertreatment, in the software the Antipollution group with SCR and AdBlue.
• Automatic transmissions: ZF Ecomat with the 9-pin Mate N-Lock connection, ZF EcoLife in mini-USB and MCP versions, and Voith Diwa.
• Brakes and chassis: Service brake, auxiliary brakes, air system preparation, suspension, steering and chassis module, including Knorr-Bremse ABS6 and ABS24/EU12 and ABS and EBS systems.
• Air suspension (ECAS): The electronically controlled air suspension that also handles entry height at stops, including Wabco ECAS CAN 2.
• Door control: Wabco MTS door control, the modular system that operates the doors.
• Climate control: Wabco ATC and ATC Coach for climate zones in the bus.
• Electronics and comfort: Central computer, electronic modules, instrument panel, lighting, heater, display, audio and starter interrupt.
• Safety: The Safety group, with emergency brake assist and lane departure warning.
• Data recording and telematics: The Data registration, telematics and FMS group, which also includes the tachograph.

Search by component instead of by bus

If the same system is fitted in buses from different manufacturers, you approach it by the component rather than the vehicle. This is useful for an automatic gearbox or a brake system that is built in by dozens of body builders.

What you can do with it

With the Bus module you read out the control units of the bus, monitor measurement values and command components. You also use it for the work the software requires: The particulate filter, the injectors, the calibrations and the service counters.

Diagnostics

• Read and clear fault codes: The control unit's fault memory, with information about the codes.
• Measurement values: The values from connected sensors displayed on screen, in figures and graph form.
• Command components: Operate components individually to check their operation.
• ECU data: Part number, serial number and software version of the control unit.
• Parameters and calibrations: Configure control units and adjust systems.

Maintenance and calibration

• Particulate filter (DPF): Force regeneration and register after replacement.
• Cylinder deactivation test: Disable cylinders individually to assess engine running.
• Injector coding: Register new injectors in the engine control unit.
• Automatic gearbox calibration: Adjust the ZF Ecomat, ZF EcoLife and Voith Diwa after gearbox work.
• Air suspension adjustment: Set the ride height and height sensors of the ECAS control system, including step height at the stop.
• Door control setup: Reconfigure the Wabco MTS door control after replacement.
• Service reminders: Reset after a service interval.

Cables and computer

The case contains a 16-pin OBD cable for the standard connection. Many bus systems also have their own dedicated diagnostic connector on the control unit, which requires a separate cable. The software itself runs on a Windows PC.

• Truck and bus cable set (29362): Cables for Volvo, Mercedes-Benz and MTU, Wabco braking systems, Renault, Iveco, the MAN TG series, DAF and MAN with 37-pin connector.
• Automatic gearboxes: JDC307A for the ZF Ecomat with the 9-pin Mate N-Lock, JDC308A for the ZF EcoLife with mini-USB and JDC309A for the EcoLife in the MCP design with the yellow 9-pin connector.
• Climate and doors: JDC304A for the Wabco ATC climate control and Wabco MTS door control on the 4+4-pin connection.
• Brakes and air suspension: JDC305A for the Knorr-Bremse ABS6 and ABS24/EU12, and JDC310A for the ECAS air suspension control on Solbus buses.
• Older buses: JDC311A for the 9-pin Sub-D on Solaris buses, JDC301A for Volvo bus ECS and JDC302A for Volvo bus ABS.
• Computer: The software runs on Windows. Cojali supplies the Jaltest Rugged PC and the A140 Rugged PAD; both are available separately in our webshop.

Which cable you need is determined by the control unit in the bus, not by the name of the coachbuilder. Check the bus itself to see which connector is on the control unit before ordering: Look at the gearbox, in the control cabinet by the door and at the OBD location of the vehicle.

Licence and renewal

With Modular, you purchase the software activation and the first year of use in one go. From the second year onwards, you renew with the update licence (29051300), each time for a further twelve months. As long as the licence is active, you receive all new software versions for the bus systems.

• Duration: Twelve months from activation, included with the software activation.
• Renewal: Annually, with the update licence (29051300).
• Installations: Maximum five PCs. The Jaltest hardware is always required to run the software.
• Registration: At activation, after each new software version, and thereafter every six months.
• Add a module later: A module purchased later will be aligned with your current licence; you pay on a pro-rata basis.
• No renewal: The module will be blocked until you purchase the update licence.

Optional add-ons

In addition to the Bus module, there are add-ons that you purchase separately. They are not required for diagnostics, but expand the reference material, support or tools. Below is what applies to buses and coaches.

• INFO Plus for Modular (70605043): The wiring diagrams and guided repair procedures. Obtain this for as many modular licences as your equipment has.
• Manufacturer module (29469): Select by system manufacturer instead of by vehicle brand, with the update licence 29481 for subsequent years. This module is not available separately and requires Modular Truck, Modular Bus or both; this set fulfils that requirement.
• Jaltest ETM (70001007): The external tester for measuring EBS modulators and sensors individually, also available as a kit with the test cables (70001008). Works only with an active commercial vehicle or modular licence and is not supplied as a standalone product.
• Jaltest ATS: One year's access to Cojali's English-language technical support desk. Renews automatically; cancellation in writing up to thirty days before the expiry date.
