3. OUTLINE OF DIAGNOSIS • Detect the malfunction of transmission line pressure solenoid drive circuit. • Judge as NG when the deviation between target current and actual current of the transmission line pressure solenoid becomes equal to or larger than the predetermined value. 4. EXECUTION CONDITION Secondary Parameters | Execution condition | 12 V battery system voltage | ≥ 9 V |
5. DIAGNOSTIC METHOD If the duration of time while the following conditions are met is longer than the time indicated, judge as NG. Judgment ValueMalfunction Criteria | Threshold Value | | Target line pressure control solenoid valve current − Measured line pressure control solenoid valve current | | > 0.2 A | Time Needed for Diagnosis: 5 seconds Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs. |
