1. OUTLINE OF DIAGNOSIS
• Detect the malfunction of turbine speed sensor signal characteristics.
• Judge as NG if the turbine speed against the engine speed is outside the possible range considering the hardware capabilities.
2. EXECUTION CONDITION
Secondary parameters | Execution condition |
12 V battery system voltage | ≥ 10 V |
Engine speed | ≥ 400 rpm |
3. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
