Quick Test: Notes
NOTE:
If vehicle has an emission compliance failure symptom, go to EMISSIONS COMPLIANCE under SYMPTOMS in TROUBLE SHOOTING - NO CODES - EEC-V - GASOLINE article.
Quick Test is divided into 3 specialized test procedures that are functional tests of EEC-V system. All self-tests are completely menu driven using the New Generation Star (NGS) scan tool. The following procedures must be followed in sequence to avoid misdiagnosis:
- VISUAL CHECK
- VEHICLE PREPARATION & EQUIPMENT HOOKUP
- KEY ON ENGINE OFF (KOEO) ON-DEMAND SELF-TEST
- KEY ON ENGINE RUNNING (KOER) ON-DEMAND SELF-TEST
- CONTINUOUS MEMORY SELF-TEST
Complete QUICK TEST before performing any system tests. Record any DTCs retrieved. Service DTCs in the following order: KOEO DTCs, KOER DTCs and then Continuous Memory DTCs. After each service or repair procedure has been completed, always repeat QUICK TEST procedures to ensure all EEC-V systems are working properly and DTCs are no longer present.
