Confirmed! Vocom I can (Vocom 88890300) work with Tech Tool 2.05.xx, while Vocom II (genuine) failed.
Tool: Vocom 88890300 interface and Vocom II
Program: Premium Tech Tool (fresh 2.0.587 install, zero issues)
I installed PTT 2.05.87 . Then updated the APCI and APCI+ from what I could find on this forum in various threads.
Truck: 2012 USA VN
Error message:
Error
It was not possible to select any operations for the selected product
Detailed information
Code: 0
Description: unit retrieved from Baldo Local is unknown: US…
While I wait for my original Vocom 2 to arrive from Volvo, I borrowed a Vocom 88890300 from a friend. It connects to the truck (2012 USA VN) but when I try to calibrate or program it gives me the error in the first picture. I also took a screenshot of the connection status (see second picture). Is this error caused by PTT (fresh 2.0.587 install, zero issues), the Vocom interface or by the APCI’s I updated from a file someone sent me. Are the European/Asian APCI’s and APCI+’s identical with the USA ones? Any opinions will be greatly appreciated, I have some work to do on the truck and can’t wait until the V2 arrives. Thank you.
Connection:
Communication unit: vocom 88890020/88840133
Mode: usb
Status: active
Tech support from real pros working for Autonumen.com:
Vocom II does work with 2.5.xx. you just need to install the drivers. If you want to have Volvo Tech Tool 2.5.xx on Vocom, try this Vocom 88890300 Interface or make sure yours same as the one displayed below
2.6.xx already has the drivers for Vocom I and II preinstalled
Firstly APCI can update online via PTT so it should be suitable for US trucks when users all are using it.
Secondly the APCI+ files available here works fine on US Volvo trucks as well as other regions. Some users have tested it.

First of all, the Piwis 2 interface is a lot more robust piece of equipment, compared to the cheesy and flimsy looking and feeling interface produced by Actia for Piwis 3.
Originally designed for the VW ODIS system, the VAS 6154 VCI is quite the service needy piece. [Breaks easily] not a hard comparison to make.
Is it worth to purchase Piwis 3 replace Piwis 2 now? Can the Piwis 2 compatible with Piwis 3 Software?
This answer for the question of whether Piwis 3 software can work with Piwis II Samtec HSX Interface?
Secondly, I thought the Piwis 3 for Porsche went cheap. [my humble opinion, way below Porsche standard!]
At the same time, there is a service from Poland and Ukraine [If I remember correctly] that can make the Samtec based Piwis 2 VCI work with Piwis 3.
Unfortunately, their charges are just as much and frankly cost prohibitive as the New Piwis 3 VCI. 2-3-4 thousand dollars for these VCIs is simply not reasonable for small operators.
They will come down in price just like the Chinese VCIs did for all manufacturers as the markets get saturated and folks are not buying them as eagerly as at the beginning of the Piwis 3 had.
They will get as much money as the market bares. [as much as people are willing to pay]
Your more pointed answers will not come in this tread Ibi. This is Cars Fan’s money-making tread, he will not volunteer any information, but if U start your own tread, U may be more likely to find out stuff.
What does the Piwis 3 updates replace Piwis 2?
Diagnostics application is used for communication with control units. You can search for, identify, code and control program units, read out the event memory, execute complex processes, change drive links and execute routines.
Guided fault finding (GFF) generates a test plan for a fault code. This test plan shows the best sequence for carrying out tests. GFF compiles a list of recommended tests, documents and wiring diagrams
Actual values/input signals functions display you the actual values and input signals of control units
Drive links/tests function displays the drive links of control units, allows you to change the parameters of these drive links and run test routines for individual control units
Maintenance/repairs function group – use this function to call up control unit-specific processes that cannot be implemented generically from the ODX data
Coding/programming function group – use this function to write coding values. Piwis 3 can code Values automatically or set manually. This function group includes (Automatic coding, Manual coding, Customer-specific settings, and Factory settings) coding modes
Logging – use this function to activate logging for diagnostics, guided fault finding (GFF) and measuring equipment applications. Temporary and permanent working log can be created
Filter – use this function to limit the view of the control units installed in the vehicle. In the diagnostic application, you can create, edit, activate, deactivate or assign filters
Wiring diagrams application is the representation of physical connections and layouts of circuits
Measuring equipment interface work for DC and AC voltage measurement, direct and alternating current measurement, diode testing, resistance measurement, continuity/open circuit testing, showing voltage, current and resistance over time (oscilloscope function)

Cold-Mode-and-No-Engine-Speed-on-Status-Flags-Caterpillar-ET-Software
Cold Mode
-The ECM limits engine power during cold mode operation and the ECM modifies injection timing during cold mode operation. Cold mode operation provides the following benefits:
Increased cold weather starting capability
Reduced warm-up time
Reduced white smoke
-The Electronic Control Module (ECM) limits engine power during cold mode operation. The ECM may modify the injection timing and the ECM may cut out certain engine cylinders. This will increase startability and this will reduce warm up time. Cold mode is activated whenever the engine coolant temperature falls below a predetermined value. Cold mode remains active until the engine has warmed or a time limit is exceeded.
Cold Mode Operation
-The ECM will set the cold start strategy when the coolant temperature is below 18 °C (64 °F).
-When the cold start strategy is activated, low idle rpm will be increased to 1000 rpm and engine power will be limited.
-Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 18 °C (64 °F).
The engine has been running for 14 minutes.
-Cold mode operation varies the fuel injection amount for white smoke cleanup. Cold mode operation also varies the timing for white smoke cleanup. The engine operating temperature is reached before the walk-around inspection is completed. The engine will idle at the programmed low idle rpm in order to be put in gear.
-After the cold mode is completed, the engine should be operated at low rpm until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low rpm and low-power demand.
No Engine Speed
-It’s normal to see the “No Engine Speed” on Status Flags while power switched ON or Engine Cranking. It will not go away until the Engine Starts, even when you are seeing Engine Speed in Status Tool on CAT ET Software.

How to perform: Fuel Rail Pump Solenoid Test using Caterpillar ET Software?
Purpose:
The Fuel Rail Pump Solenoid Test function can be used to verify the operation of the fuel rail pump solenoid. This test provides a method for determining whether or not an open circuit or short circuit is present.
-Connect CAT ET Software, Read More: How to Connecting Caterpillar ET Software to the ECM
-Open Menu: “Diagnostic”- “Diagnostic Test” – “Fuel Rail Pump Solenoid Test”
-Click on “Power All” or “Start” and wait the process until completed (Mode: powered)
-On tab “Test Results” is Not OK (*Short), indicates that the Fuel Rail Pump Solenoid is damaged/shorted.
NOTE:
-This test identifies an open circuit or a short circuit for the Fuel Rail Pump Solenoid. The test activates the solenoid while the engine is not running. A good solenoid will create an audible click when the solenoid is activated. CAT ET indicates the status of the solenoid as “OK”, “Not OK (Open)”, or “Not OK (Short)”.
Test Operation:
During the Fuel Rail Pump Solenoid Test, the ECM pulses 105-volt to the solenoid. The pulses are sent at the proper time and for the correct duration for a given engine load and speed. The ECM monitors the current flow through the circuit for each solenoid. If the current flow is too high or too low, the ECM activates one of the following diagnostic codes:
1779-5 Fuel Rail Pump #1 Output Current Below Normal
1779-6 Fuel Rail Pump #1 Output Current Above Normal
1780-5 Fuel Rail Pump #2 Output Current Below Normal
1780-6 Fuel Rail Pump #2 Output Current Above Normal
