This instruction show you guide on how to use Volvo PTT to diagnose engine performance for Volvo FM440 truck.

Preparations:

Diagnose Volvo FM440 Truck Engine Performance by Volvo PTT:

Connect Volvo PTT interface (VOCOM recommend) to FM440 truck DLC and then run Volvo PTT

After then select “Test”–>”28-Ignition and control system”–>”Sensor Values,Monitoring”

After then click “Start” button

The operation exists in several variants.

Select the variant that corresponds to the connected vehicle/machine.

Here select “D13A” and click “OK”

The purpose of this test is to check that the sensors give plausible values.Evaluation of the sensor value is best done on an engine at normal working temperature,at low idle with the vehicle stationary.The test can also be used to check the sensor values under other conditions.

When it access this window,click “Play” button and check the conditions requested.

After then the screen will display the value of the sensors on the Engine.

Here are “Fuel Supply Pressure”,”Boost Pressure”,”Intake Manifold Temperature”….and others

For maximum results,this check must be carried out at the engine working temperature and engine position when low idle

So the purpose of “Sensor Values Monitoring…” is to check or evaluate the values displayed by the sensor.

For “Crankcase Pressure Sensor”,the maximum normal value is 1KPa

For the alarm limit,which is 8 kPa.

What’s the difference between Porsche Tester Piwis III original and clone:

The genuine and copy differ in hardware only.

They share the same functions and features.

Why you should have a Porsche Piwis 3:
*   vehicle coverage up to 2018: 911, Macan, Cayeme, Panamera, Boxter Cayman
*   Fast and stable connection Simulation mode ( diagnostic session without VCI connection )
*   Support online immobilizer programming
*   New DoIP diagnostic technique based on Ethereum for post-2017 Porsche
*   Developer mode enabled

What’s the difference between Porsche Piwis Tester II and Piwis 3:
PIWIS Tester III covers all new Porsche models like new Panamera 971, Cayenne 9Y0, Cayman 981 GT4 clubsport, etc., which are not supported by PIWIS II at all and will never be supported in the future. PIWIS Tester III also supports full range of diagnostics functions for all the Porsche models which have ever been released.

What can you do with Piwis 3 v37.250.015:
*   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 displays 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. Values can be coded 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 is used 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)

Which Porsche model and year can be done with Piwis 3:
Piwis 3 is confirmed to work with
all Porsche from 1998-2018:
Porsche 911(997) (991)
Boxster/Cayman (987)
Cayenne up to MY 2010
Cayenne from MY 2011
Panamera

Especially the latest models:
Paramera (971) 2018
Caynenne (92A) 2018
Macan (95B) 2018
911 (991) 2018
and other old models

Any successful tests on Porsche with Piwis 3?

Look here: test on Panamera 971 (after 2017)
