Quick Test: Notes

2010 Ford Focus SES, 2D Coupe, StandardSECTION Notes
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The quick test is divided into 3 specialized tests:

  1. Key On Engine Off (KOEO) On-Demand Self-Test
  2. Key On Engine Running (KOER) On-Demand Self-Test
  3. Continuous Memory Self-Test

The quick test checks the integrity and function of the electronic engine control (EEC) system, and the hybrid-electric system. The results of the quick test are requested and displayed on the diagnostic tool. The quick test also provides a quick end check of both the powertrain control system and the hybrid-electric system. It is usually carried out at the start of each diagnostic procedure with all accessories off. The quick test is also carried out at the end of most pinpoint tests for verification of the repair and to make sure no other faults were incurred while repairing a previous fault. A system pass is displayed when no diagnostic trouble codes (DTCs) are output and a diagnostic tool communication error does not exist. System pass means that hardware monitored by the powertrain control module (PCM) or the transaxle control module (TCM) is functioning within the normal operating limits. Only a system pass, a DTC, or an incomplete on board diagnostic (OBD) drive cycle (P1000) is displayed.

NOTE: Do not carry out consecutive quick tests without turning the key to OFF position for a minimum of 15 seconds.
