1. Ensure self test is DEACTIVATED, then START and run the engine at 2,000 rpm for two minutes. NOTE: IF the engine starts but stalls, or stalls during self test, refer to pinpoint test step S2. See: Pinpoint Tests\S - System Check\S2 - Check For RPM Drop
2. Turn the engine OFF and wait for ten seconds.
3. ACTIVATE the self test by grounding the STI connector.

4. Start the engine.
5. After the engine ID code, depress and release the brake pedal, then turn the steering wheel 1/2 turn and release it. If the vehicle is equipped with an E4OD transmission cycle the Overdrive Cancel Switch (OCS) .
6. When the dynamic response "goose" code appears, briefly go to wide open throttle.
7. Record all codes displayed. NOTE: Engine running service code 98/998 indicates vehicle is in Failure Mode Effects Management (FMEM) and DID NOT PASS the Key ON Engine OFF (KOEO) on demand/continuous memory self test. Engine running self test cannot be performed while in FMEM. Rerun KOEO self test and correct all fault codes. See: Key On Engine Off (KOEO) Self Test
8. Turn OFF the engine and DEACTIVATE the self test.
9. If a pass code (11) was received in the KOER test, proceed with the next step. See: Address Continuous Memory DTC If any other codes are received, refer to the proper diagnostic trouble code chart for the diagnostic path. See: Diagnostic Trouble Code Tests and Associated Procedures
