6.In MxTransIt, click on the PLT Test Manager Transform to select it and display its Properties box.

7.Click the Launch MxPLTConversionTool verb to open the tool.

8.Select the “TestCases Generation” tab to generate Scenarios and TestCases dynamically based on selected inputs.

9.Following are the inputs for the TestCase Generation tab of the Mx‑PLT tool.

a.Select TestCase Definition File. Click the browse button () to select the file. Once the input TestCase definition file is selected, fields in the GUI (Vendor Spec, Bus Interface, Baud Rate, DUT type, Supply voltage Range, Crank Communication) are automatically loaded. Enter ECU response ID at Rx CAN ID.

b.DUT Type. If the DUT does not have a 120-ohm termination-resistor, select "No Internal Termination". If the DUT has the internal 120-ohm termination-resistor, select "Internal Termination_120Ohms".

c.Change the Baud Rate as per DUT type.

d.Select the Supply Voltage Range as per DUT supported voltage ranges “Standard” (9V to 16V) or “Extended” (6V to 26.5V).

e.Select Tstart-up Measurement:

•Select "With Rx" to measure the start-up time between the first received message from DUT and the fault removal time.

•Select "With Tx" to measure the start-up time between the first successful transmit message from PLT and the fault removal time. In this case, PLT transmits an additional TEST message (0x111) with 10 ms periodicity from just before fault removal up to 3 sec.

f.Crank Communication. If DUT supports communication during cranking, select “Supported”. Otherwise, select the “Not Supported” option.

g.Select Ignition Type:

•Select “Input High” if DUT wakes-up with 12V – 14V on ignition line.

•Select “Input Low” if DUT wakes-up with 0V on ignition line.
