ENGINE ON-BOARD DIAGNOSIS [KL]
On-Board Diagnostic (OBD) Test Description
OBD Test is divided into three special tests: Key On
Engine Off Self-Test, Key On Engine Running
Self-Test and Continuous Memory DTCs Self-Test.
The OBD test checks the integrity and function of the
powertrain control system and outputs the test results
when requested by the NGS Tester. If also provides a
quick end check of the powertrain control system, is
usually performed at the start of each diagnostic
procedure with all accessories off and is performed at
end of most troubleshooting tests for verification of
repair and make sure no other faults were incurred
while servicing a previous fault.

System Pass
A system pass will be displayed when no DTCs are
output and no NGS Tester communication error
exists. System pass means that hardware monitored
by the PCM is functioning within normal operating
limits. When using the NGS Tester, all step by step
instructions are defined in the NGS instruction
manual. When using a generic scan tool, KOEO and
KOER self-tests may not be supported. Refer to the
manufacturer’s manual for details.
