The Read KOER Codes function activates the KOER self-test
which retrieves KOER DTCs that are present when the engine is
running.When the trouble condition is inactive, the KOER code is
no longer 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.
