Unique Attributes of
Automotive Functional
Testing
Functional testing of automotive
ECMs can strain the capabilities of
a typical test system. The TS-5020
can address a wide range of ECMs,
from climate control to ABS to air bag
control. Table 1 takes a closer look
at the test requirements for some of
these ECMs and the solution Keysight
TS-5020 can provide.
Test Requirements
The advancement of electronically
controlled functions in today’s
automobiles require a wide range
of capabilities: fast switching,
versatile signal generation and serial
communications; to name a few.
The TS-5020 is designed to meet
these challenges by increasing
production volume with higher
throughput while reducing the cost
of test. As summarized in the table
below, the TS-5020 offers a variety of
solutions for each of the critical test
requirements.

Test Methodologies
The ability to test many types of
modules with one system improves
development leverage. Adding test
methodologies that accelerate
the measurement of each module,
regardless of type, is the next step
towards lower-cost test.
The Keysight TS-5020 offers two
approaches that improve the flexibility
and speed of the testing process. One
is UUT-assisted testing in which the
ECM becomes an active participant in
the testing process. The other is the
throughput-multiplier strategy which
enables batch testing of multiple
identical ECMs.
UUT-Assisted Test
As shown in figure 4 above right, most
ECM designs include a serial interface.
Communication protocols vary by
manufacturer, but most comply with
OBD2 standards. Variations include
ISO-9141, J1939/CAN and J1850. The
serial link is used in the automobile
itself and can also assist in the testing
of the module.
As a programmable device, the ECM
can be loaded with either operational
code or test code. Operational code
is either present in ROM during test
or is downloaded when the unit is
shipped. Test code is either included
in ROM or downloaded through
the serial link into the module. By
using test code as part of the test
program, the TS-5020 establishes a
set of conditions to which the ECM
responds. This test approach is
known as UUT-assisted test.
