Jaltest 29303 is the software activation for Jaltest CV, the diagnostic solution for trucks, buses, trailers and light commercial vehicles. This is the entry-level product in the module range: you purchase it once, we bind it to the serial number of your Jaltest Link, and then it appears in the Jaltest Diagnostics start menu.
The software runs on a Windows PC and reads control units via the Jaltest Link; it will not launch without this interface. The initial purchase does not expire – the module remains yours – but from year two onwards, you will need the update licence (29051) to access new software versions.
KEY BENEFITS
POINTS TO NOTE
Applications and functionality
Jaltest CV is the Jaltest diagnostic tool for trucks, buses, trailers and light commercial vehicles. This activation unlocks that module. What you can do with it afterwards depends on the vehicle and the interface you use.
What you can do with it
- Systems and fault codes: The software recognises the control units present and reads out the fault codes, with their descriptions.
- Live readings: Read parameters whilst the vehicle is running, from engine speed and pressure to temperature.
- Actuation: Direct actuation of components to verify they respond.
- Calibrations and settings: The calibrations and parameter settings that Jaltest offers per system.
- Symptom-based fault finding: Guided search paths that start from the complaint rather than the fault code.
- Technical information: Releases, procedures and manual diagnostics for the systems you access.
- Expert mode: Select a control unit manually when automatic selection is not suitable.

CV or Modular?
With CV, you purchase comprehensive coverage across the entire commercial vehicle segment in a single licence. If you work exclusively with one vehicle type, the Modular option offers a more focused approach: Modular Truck (293100), Bus (293300), Trailer (293500) and LCV (293600) are purchased individually.
Four editions
Jaltest CV is available in four versions with identical coverage. The difference lies in what you purchase – a one-time purchase, your first year included, a renewal or an upgrade to software you already own – not in what you can do with it.
| Version | What it is | Reference |
|---|---|---|
| Software activation (this product) | One-time purchase; the module remains yours | 29303 |
| Software licence | The module with the first year of usage included | 71502018 |
| Update licence | Twelve months' extension, from the second year onwards | 29051 |
| Software upgrade | Adds this segment to Jaltest software from another segment | 71501001 |
What you need
To diagnose with Jaltest CV, you need more than this product. The complete set-up is shown below.
- Jaltest Link: The diagnostic interface. Required, even to start the software on a PC.
- The module itself (29303): This product. You purchase the module once; the module remains yours.
- Update licence (29051): Twelve months' renewal, from the second year onwards.
- Adaptor cables (optional): Cable set for truck and bus (29362), Cable set for trailer (70002024) and Cable set for refrigeration units (29989). If you do not have these, you can connect using the multi-pin set included in your Jaltest diagnostic case.
What's included
- 1x Jaltest (29303) | CV (Commercial Vehicles) | Software activation, a one-time purchase, delivered digitally to the serial number of your Jaltest Link
How does it work in practice?
From order to working module there are four steps. The serial number of your Jaltest Link is all you need to find yourself.
- Provide the serial number: Include the serial number of your Jaltest Link in the notes field when you place your order; this is required.
- We activate: We bind the module to that serial number, typically within one working day of your order.
- Confirmation by email: You will hear from us as soon as the module is on your serial number.
- Update software: Start Jaltest Diagnostics and retrieve the module; Jaltest CV will then appear in the start menu.
