1. OUTLINE OF DIAGNOSIS
Detect the AVCS system malfunction.
Judge NG when the amount of AVCS actual timing advance does not approach to the amount of AVCS target timing advance.
2. EXECUTION CONDITION
Secondary parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
AVCS control | In operation |
|Target timing advance change amount (per 64 ms)| | < 3.2 °CA |
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously when the engine speed increases and AVCS operates.
4. DIAGNOSTIC METHOD
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.
Judge as NG when the following conditions are established within the predetermined time.
Malfunction Criteria | Threshold Value |
Σ|(Target position − Actual position)| | > 4000 °CA (Bank 1) > 4000 °CA (Bank 2) |
Time needed for diagnosis: Less than 1 second
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
