Diagnostic Method
- When the conditions during which the differences of AVCS target timing advance amount and AVCS actual timing advance amount is large continues for certain amount of time.
- When the differences of target timing advance amount and actual timing advance amount is calculated during AVCS control, and the difference per predetermined time is the specified value or larger.
- Abnormality Judgment
Judge as NG when the following conditions are established within the predetermined time.
Judgment Value
ABNORMALITY JUDGMENTMalfunction Criteria Threshold Value Σ(Target position - Actual position) > 7000°CA (Bank 1)
> 7000°CA (Bank 2)or Σ(Target position - actual position) < -12000°CA(Bank 1)
<-12000°CA(Bank 2)Time Needed for Diagnosis: 60000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established within the predetermined time.
Judgment Value
NORMALITY JUDGMENTMalfunction Criteria Threshold Value Σ(Target position - Actual position) ≤7000°CA(Bank 1)
≤7000°CA(Bank 2)
and
≥ -12000°CA(Bank 1)
≥ -12000°CA(Bank 2)Time Needed for Diagnosis: 60000 ms
