Read KOER Codes

The Read KOER Codes function activates the KOER (Key-On-Engine-Running) self-test which retrieves KOER DTCs that are present when the engine is running.When the trouble condition is inactive, the KOER Code will no longer be sent through the data stream. This function also performs a Computed Timing Check for EEC-IV vehicles manufactured from 1984 through 1991.

The DTCs are transmitted in two formats which transmit the same information:

Slow Codes are regular service codes that allow the user to identify the faults with an analog voltmeter or the check engine light. Slow codes are transmitted within 3 minutes.

Fast Codes are transmitted within seconds and must be read with a diagnostic tool. MECS vehicles do not support Fast Codes.
