Quick Test Description: Notes

The Quick Test is carried out by retrieving the key ON engine OFF (KOEO), key ON engine running (KOER), and continuous memory diagnostic trouble codes (DTCs).

Quick Test is divided into 5 specialized tests:

1. Retrieve/Clear Continuous DTCs
2. KOEO On-Demand Self-Test
3. KOEO Injector Electrical Self-Test
4. KOER On-Demand Self-Test
5. KOER Glow Plug Monitoring Self-Test

All are described below.

Quick Test checks the integrity and function of the powertrain control module (PCM) and outputs the test results upon demand. The Quick Test also provides a quick end check of the powertrain control system and is usually carried out at the start of each diagnostic procedure. It is also carried out at the end of the pinpoint tests for verification of repair and to make sure no other concerns were incurred while repairing a previous concern.
