When programming a second Injector the screen freezes.
When the operator programmes an injector there is an option to press Y to programme a second injector or an option to press N to finish and come back out of the menu. When selecting Y the screen will freeze – instead select N, it will come out to the Injector Reprogramming menu. Then go in again and chose the next injector to programme, this should be repeated until all injectors are programmed.
Hill Descent Control (HDC) helps control your speed as you descend steep or slippery slopes. Once engaged, HDC will monitor your vehicle's speed via the ABS sensors and automatically apply the correct braking force for a safe descent. It operates in both high and low range and in both forward and reverse gear, allowing you to concentrate fully on steering and manoeuvring.
Provides safe handling when accelerating or cornering and includes compensation for trailers. It constantly monitors key indicators, correcting any tendency to over- or under-steer and applies the ABS braking system selectively to individual wheels to correct any tendency to deviate from your chosen line.
This new menu under Functional tests allows the user to alter certain values and functions supported under the control unit being interrogated.
This Option should only be used by technicians familiar with the operation of these adaptive values and functions.
These values and functions, if incorrectly modified, can lead to the control unit being disabled or corrupted and when Technician enters this adaptation menu he/she is greeted with a warning to this effect. Information pertaining to the particular vehicle under test should be to hand when using the Adaptation menu.
The amount of Adaptation channels per control unit and per vehicle varies significantly.
Channel 00 will (on control units that support it) change all settings on the controller to original factory default settings.
Once again it is important to be aware of what each channel represents. The channel numbers are not consistent and are dependant on the type of system control unit and protocol it uses and should not be adjusted without the appropriate documentation.
It is also possible to adjust the injection duration on some (But not all, and again the channel appropriate to this function is vehicle specific).This function be implemented to facilitate easier starting on older engines although this should not be used in place of exhaustive checks to ensure that the fault is not due to something else.
Throttle Body cannot be supported through adaptations; you need to go to Basic Settings under Expert mode.

“ I have always owned my own personal diagnostic tool in addition to what is made available to me through my work. In fact I have always owned Snap-on or Sun-branded equipment since the original ‘red brick’ itself. I traded up to the MODIS™ some five months ago, primarily for the extended data capture capability and also to be able to carry out detailed secondary diagnosis, via the built in 4-channel scope.
The tool is a compact, reliable unit with accurate and regularly updated software – all things I have come to expect from Snap-on diagnostic equipment. Couple this with portable infra-red printing and the capability to save and transfer information from any screen at any time and you are left with a truly powerful, portable diagnostic tool.”
“ I still find it hard to believe that I recently bought a Snap-on Heritage Scanner™ diagnostic tool and amazingly it has paid for itself in only seven weeks .”
So says Steve McCauley, After Sales Manager of Blyth Valley Ford in Northumberland. Steve has held his current position for nearly eight years and has been in the industry now for 32 years.
“ I had been thinking seriously for some time of purchasing an allmakes hand-held diagnostic tool but had held back for budgetary reasons. However, we were getting stuck so many times with running problems that we were unable to diagnose and warning lights were coming on which we were unable to fully understand. away …………… ………………………….
Tony Allen of A&S Auto Repairs of Gravesend in Kent is an independent mobile technician, who works for both garages and for private individuals across a wide area of South and South East London, as well as the whole of Kent. He originally set up his operation in 1990. He purchased a Snap-on Scanner™ in the Summer of 2005.
“ I had previously used a diagnostic tool from another supplier but had become conscious that it was limiting the amount of work that I could take on, because it was not updateable and there were many new vehicles on the road that I was unable to handle. I knew of Snap-on because of the Company’s strong reputation in the UK trade and once I saw Scanner™ I knew that it was the solution to my problems. What I liked best was its simplicity. It is really, really easy to use and is so much better quality than my previous diagnostic tool. In fact In fact the hardest part of operating Scanner™ is just getting it out of its box! It also gives my customers confidence ………………….
Justin Hatcher is the Workshop Manager at PM Autos, an independent garage in Dartford in Kent owned by Pat Santer. The Company has been in operation for around 20 years and, in addition to Pat and Justin, employs two apprentices.
“ We had previously used a Snap-on Scanner™ as one of the three diagnostic machines that we use but made the decision
to invest in MODIS™ just over two years ago because it seemed a much better all-round diagnostic tool. We have been more than happy with it. It is very easy to handle, with very few controls and we particularly like the nice big colour screen. It is a very nice piece of kit compared to what else is on the market and it makes a mechanic’s life very easy to navigate around. We also find the regular software updates very valuable in always keeping us fully up to date. Although we still have the other two diagnostic tools, nine times out of ten we will always pick up MODIS™ first, because it gets the job done”.
You can now upgrade cartridge’s that contain US software. This depends on the business unit settings on ScanBay II server.
Please note: Individual modules cannot be programmed: only a full bundle can be installed.
Snap-on Diagnostics does not support a mixture of European, US or Australian software modules on one PVCI. A warning message will be displayed if different types of modules are mixed. Snap-on will not provide support for PVCIs that contain mixed modules.
PVCI’s or TSI’s that contain a black/red label will not be recognised by ScanBay II. To solve this problem see SB 1079 on how to add it to the ScanBay II database and to get an upgrade price invoiced instead of a new buy.
Further there will be some unknown modules. To remove them you have to format the cartridge as described before. Do this only after you have saved the cartridge details text file, to be able to get an upgrade price!
A PVCI can be corrupted if it is removed from the ScanBay programmer during programming.
A PVCI can also be corrupted in the Scanner itself. When a PVCI is corrupted it seems as if the PVCI is empty and it has a different, or incorrect Electronic ID. We have now devised a system that recognizes corrupt PVCI’s. This system will prevent you from buying licenses and carrying out any further programming.
In some cases you can repair a corrupt PVCI in ScanBay II. Select “Update Cartridge System Files” from the toolbox menu. After updating these files you must remove the PVCI from the ScanBay programmer and reinsert it again. Wait long enough so that ScanBay II can recognise that the PVCI was removed. When it is repaired ScanBay II will now recognise the cartridge again. It could be that all modules are deactivated, grey. If this is the case, they need to be reprogrammed. The licences should still be there for this PVCI.
If this procedure does not work, then the cartridge needs to be repaired in our repair centre. See Service Bulletin SB 1086 for detailed information about this repair procedure.
A PVCI Defrag will take place automatically in the Scanner the first time after it is programmed in ScanBay II. This can take up to 5 minutes. The defrag will start automatically when:
A legacy module (i.e. EOBD or AFL) is selected for the first time.
After a vehicle is selected in a VAT module. A VAT module is shown in orange in ScanBay II.
During defrag, it looks that the scanner is locked. Therefore we advise that you do this before delivering the PVCI to the customer.
After programming a cartridge, please check that the cartridge contains the software that is programmed on it by removing it from the ScanBay programmer and re-inserting it. You should also test it in a Scanner.
