NO.12 TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION [FN4A-EL]
| 12 | Torque converter clutch (TCC) non-operation |
|---|
| DESCRIPTION | TCC does not operate when vehicle reaches TCC operation range. |
| POSSIBLE CAUSE | Basically, TCC does not operate when fail-safe is operating. Verify DTC first. CAUTION: If TCC is stuck, inspect it. In addition, inspect oil cooler for foreign particles which may have mixed in with ATF. TCC burned (1) Input sensor system malfunction TFT sensor VSS Input/turbine speed sensor Sensor GND (2) Output solenoid valve system malfunction (Sticking) Shift solenoid E malfunction Shift solenoid A malfunction (3) Control valve body system malfunction (Poor operation, stuck) TCC hydraulic pressure system APP sensor malfunction (Not operation liner) Input/turbine speed sensor or VSS malfunction Brake switch malfunction (Always ON) ECT sensor malfunction Excessive amount of ATF NOTE: Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See «BASIC INSPECTION [FN4A-EL]».) |

NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [FN4A-EL]
| 16 | Judder upon torque converter clutch (TCC) operation |
|---|
| DESCRIPTION | Vehicle jolts when TCC is engaged. |
| POSSIBLE CAUSE | Poor TCC engagement due to either slippage because TCC is stuck or line pressure is low. CAUTION: If TCC is stuck, inspect it. In addition, inspect oil cooler for foreign particles which may have mixed in with ATF. Torque converter clutch piston slipped, burned Line pressure high Shift solenoid A malfunction Shift solenoid E malfunction Control valve body malfunction Body GND malfunction Pressure control solenoid malfunction Signal malfunction VSS malfunction Sensor GND malfunction TFT sensor malfunction APP sensor malfunction Input/turbine speed sensor malfunction Torque converter malfunction NOTE: Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

| 19 | Excessive shift shock on torque converter clutch (TCC) |
|---|
| DESCRIPTION | Strong shock is felt when TCC engaged. |
| POSSIBLE CAUSE | Malfunction is same as for symptom troubleshooting "NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION". (See «NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [FN4A-EL]».) |
