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 JUDGMENT VALUE Malfunction Criteria Threshold Value Sum(Target position - Actual position) > 8000°CA (AT model) (Bank 1) > 8000°CA (AT model) (Bank 2) > 5300°CA (MT model) (Bank 1) > 5300°CA (MT model) (Bank 2) or Sum(Target position - Actual position) < -8000°CA (AT model) (Bank 1) < -8000°CA (AT model) (Bank 2) < -5300°CA (MT model) (Bank 1) < -5300°CA (MT model) (Bank 2) Time Needed for Diagnosis: AT model: 30000 ms MT model: 20000 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
| Malfunction Criteria | Threshold Value |
|---|---|
| Sum(Target position - Actual position) | < or = 8000°CA (AT model) (Bank 1) < or = 8000°CA (AT model) (Bank 2) < or = 5300°CA (MT model) (Bank 1) < or = 5300°CA (MT model) (Bank 2) and > or = -8000°CA (AT model) (Bank 1) > or = -8000°CA (AT model) (Bank 2) > or = -5300°CA (MT model) (Bank 1) > or = -5300°CA (MT model) (Bank 2) |
