Quick Test Description: Notes

Quick Test is divided into 5 specialized tests:

  1. Retrieve/Clear Continuous diagnostic trouble codes (DTCs)
  2. Key On Engine Off (KOEO) On-Demand Self-Test
  3. Key On Engine Off (KOEO) Injector Electrical Self-Test (Click Test)
  4. Key On Engine Running (KOER) On-Demand Self-Test
  5. Key On Engine Running (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. 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 pinpoint tests for verification of repair and to make sure no other faults were incurred while repairing a previous fault.
