Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
7. FAIL SAFE
• Ignition timing whole learning compensation:
– Enter the initial value (whole learning compensation factor = 0.5, Variable amount of whole learning
compensation factor = 0.25) to the whole learning compensation factor and variable amount of whole
learning compensation factor when IG OFF, and then make the whole learning incomplete.
– Enter the initial value (whole learning compensation factor = 0.5, Variable amount of whole learning
compensation factor = 0.25) to the whole learning compensation factor and variable amount of whole
learning compensation factor when making a normality judgment
→
abnormality judgment, and then make
the whole learning incomplete.
• Ignition timing partial learning compensation:
– Enter the initial value (0° CA) to the compensation value of partial learning zone with IG OFF.
– Enter the initial value (0° CA) to the compensation value of partial learning zone when making a nor-
mality judgment
→
abnormality judgment.
• AVCS control:
– Maximum timing retard learning is not complete or maximum timing retard learning completion is not ex-
perienced.
–
⇒
ISC feedback compensation: Do not perform the AVCS actual timing advance compensation.
– Make the oil flow control solenoid valve driving duty a predetermined value (9.36%).
