3. OUTLINE OF DIAGNOSIS Diagnosis 1 • Detect the malfunction of transmission forward/reverse clutch pressure solenoid drive circuit characteristics. • Judge as NG when the deviation between set current and actual current of the transmission forward/reverse clutch pressure solenoid drive circuit becomes equal to or larger than the predetermined value. Diagnosis 2 • Detect the malfunction of transmission forward/reverse clutch pressure solenoid drive circuit characteristics. • Judge as NG when the transmission forward/reverse clutch pressure solenoid drive current is within the predetermined value. 4. EXECUTION CONDITION Secondary Parameters | Execution condition | Diagnosis 1 | | 12 V battery system voltage | ≥ 9 V | Diagnosis 2 | | 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 | Diagnosis 1 | | |Target forward & reverse clutch pressure control solenoid current − Measured forward & reverse clutch pressure control solenoid circuit| | > 0.2 A | Diagnosis 2 | | Measured forward & reverse clutch pressure control solenoid current | > 1.08 A | | | and | | | ≤ 1.6 A | Time Needed for Diagnosis: 5 seconds Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs. |
