Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
6. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
8. FAIL SAFE
Knocking compensation
When normal: Learning ignition advance angle value = knock F/B advance angle + entire learning advance
angle value + portional learning advance angle value
Failure: Learning ignition advance angle value = –5.0°CA
Knock F/B advancing angle = 0°CA
Whole learning prohibited
Portional learning prohibited
9. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
