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.
