PGM-FI SYSTEM
CURRENT OTC/FREEZE DTC
The OTC is indicated in two ways according to the failure status.
• In case the ECM detects the problem at present, the MIL will start blinking the OTC. It is possible to read out the MIL blink
pattern as the current OTC.
• In case the ECM does not detect any problem at present but has a problem stored in its memory, the MIL will not blink. If it is
necessary to retrieve the past problem, read out the stored OTC by following the OTC readout procedure (page 4-11 ).
MCS
