This function is used to burn off the soot particles in the particle filter. It is particularly useful for cleaning the DPF when the vehicle is always driven in an urban environment.

Step By Step

1.

Resolution

For 2005-2006 models, use the following procedure for the Z19DT and Z19DTH engines:

Caution: Fire Hazard Warning! 

Run the regeneration outside and make sure that there is no flammable material under or behind the vehicle. The regeneration process generates very high exhaust temperatures. Do not fit an exhaust extractor.

Regeneration burns the soot particles trapped in the particle filter and the process takes about ten minutes.

Place the gear selection lever in the P position (or in neutral for manual transmission).

Make sure the parking brake is engaged.

Start the engine.

Wait until the coolant temperature reaches normal running temperature (80°) before attempting to start the regeneration procedure or the process will not start.

Do not touch any of the controls during the process.

The engine speed will rise (3500 RPM) and the injection will be retarded to greatly increase the exhaust temperature.

White smoke may be produced by the regeneration process.

Do not click on the OK button for "Operation finished" (see illustration 1).

Wait until the process stops automatically (engine speed will drop to idle automatically) and leave the engine idling for at least 10 minutes before switching off.

If the cycle is interrupted (by accidentally pressing a pedal for example), it is possible to restart the process at the next key on.

Soot particle burning (regeneration) must be carried out in the open air. The filter particle will reach extremely high temperatures. The vehicle must be parked on a non-flammable surface. To avoid consequent damage, only run the regeneration procedure once! The combustion process can take up to 40 minutes.

Test conditions

  • Engine at idle.
  • Minimum coolant temperature greater than 72°C (Note: if the temperature has not been reached, the process will not start)
  • No pedal must be depressed.

Procedure

1. Click on "OK" to start the operation.

2. A dialogue box will display the coolant temperature. Wait until the temperature reaches the correct value. See test conditions.

3. Click on "OK" to start the regeneration.

4. A dialogue box will display the regeneration status. If the combustion must be cancelled, select "Cancel" and switch the ignition off once the engine speed has stabilized.

5. Regeneration takes around 40 minutes.

6. A dialogue box will display: "Combustion finished" when the process has reached a successful conclusion.

In case of failure or cancellation, check the test conditions and replace the particle filter as necessary.

    Electronic Injector Test Kit

    With today’s Common Rail injector technology, it’s no longer sufficient to just measure resistance to check a coil’s health – you also need to measure inductance for an immediate and accurate assessment. Previously separate tools would have been needed for this. Not with our Electronic Injector Test kit. Otherwise known as the ‘buzz tool,’ or part number YDT720, you’ll be able to quickly test the electrical integrity of all makes of solenoid Common Rail injectors on vehicle. The simple,hand-held tool measures the injectors core criteria, allowing you to quickly compare values and identify if any are not within a comparable performance range, or confirm specific electronic failures which may indicate an unrepairable injector. You can also use it in conjunction with our solvent cleaning kit to resolve early-stage lacquering. All with just one tool, saving significant time and cost for the garage.

    Pass-Thru Diagnostics

    Our DS-Flash™ pass-thru package does what its name suggests – it allows garages to ‘pass-thru’ to vehicle manufacturer’s websites to access valuable repair and maintenance information. With DS-Flash you’ll be able to perform dealer-level diagnostics, download software updates, reprogram ECUs and access OE technical data and service schedule information, without the need for expensive dealer-only tools. The full kit is compliant with VM programming requirements and comes complete with a DS-Flash™ VCI, cables, a battery support unit and a laptop PC, pre-configured for key brands. Users will also benefit from our 12-month support package, which includes training and technical support for both the equipment, registration to the VM web portal and installation and use of the VM software. So from now on, jobs that were turned away, or referred back to the dealer network, can now be managed in house.
    Part diagnostics fuel injection hd3000 high pressure tool

    HD3000 High Pressure Diagnostic Tool

    Designed for specialist workshops, our patented HD3000, part number YDT840, simplifies the diagnosis of faults with current and future-generation diesel and gasoline high pressure fuel systems, on all vehicle types. With one tool users will be able to safely set and electronically control any pressure testpoint , up to 3000 bar, in order to investigate the full range of pressures and analyse the performance of the fuel injection system – previously this level of flexibility, accuracy and pressure capability could only be achieved with a system-dedicated test bench. Containing an electronic control device, hydraulic block and electrical device, it incorporates multiple dedicated test routines, as well as an IMV cleaning procedure. All this can be achieved without changing any ECU parameter, dismantling the fuel injection system, or taking the vehicle out on a road test – helping workshops save valuable time and deliver faster service turnarounds.

    LP35 Low Pressure Diagnostic Tool

    Designed for the garage technician, LP35, part number YDT810, is a highly precise, ultra-fast, affordable hand-held tester for the low-pressure side of light, medium and heavy duty vehicles. With a single tool, you can perform quick and accurate pressure analysis across a wide range of positive and negative pressures, from minus one through to positive 35 bar -that’s why we called it the LP35. Unlike other entry level equivalents, it’s also compatible with most low-pressure circuits, as well as different fluids, so you’ll no longer need separate negative and positive pressure tools, saving both time and money. Add to this its static and dynamic functionality, and you’ve got a highly versatile, highly capable low-pressure tool.

    Fuel Injection Diagnostics

    Due to the design of today’s advanced fuel injection technology, electronic diagnostic tools require additional support to accurately trace faulty components – the ECU diagnostic software  can often go no further than failure mode identification, which does not always pinpoint the particular part of the system that has failed and can result in the unnecessary replacement of complete systems. That’s where we come in. We know exactly what is required when diagnosing this technology – after all, the chances are we designed and manufactured it in the first place. So, we’ve developed a range of simple, low-cost, on-vehicle diesel diagnostic tools to help you and your customer save time and money.

    Sealed Rail Diagnostic Kit

    Because Common Rail systems operate at extremely high pressures, any loss in pressure will have a knock-on effect on the vehicle – causing a progressive reduction in power and even a complete engine shut down. It is therefore imperative that any such issues are identified and resolved as early as possible. We have just the answer. Our Sealed Rail diagnostic kit, part number YDT850, provides simple, low-cost on-vehicle capability for all makes of Common Rail pumps and injectors. Consisting of a sealed rail pressure tester and injector back leakage measurement equipment, users can check the pressure being generated by a Common Rail pump and identify individual injectors that fail, meaning only faulty components will need to be replaced.
