NO.12 TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION [FS5A-EL]
| 12 | Torque converter clutch (TCC) non-operation |
|---|
| DESCRIPTION | TCC does not operate when vehicle reaches TCC operation range. |
| POSSIBLE CAUSE | Basically, the TCC does not operate when the fail-safe is operating. Verify the DTC first. CAUTION: If the TCC is stuck, inspect it. In addition, inspect the oil cooler for foreign particles which may have mixed in with the ATF. TCC burnt Input sensor system malfunction TFT sensor VSS Input/turbine speed sensor Sensor ground Output solenoid valve system malfunction (Sticking) Shift solenoid A malfunction Shift solenoid E malfunction Control valve body malfunction system (Poor operation, stuck) TCC hydraulic pressure system APP sensor malfunction (Not operating linear) Input/turbine speed sensor or VSS malfunction Brake switch malfunction (Always ON) ECT sensor malfunction NOTE: Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See «ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FS5A-EL]».) (See «BASIC INSPECTION [FS5A-EL]».) |

DESCRIPTION & POSSIBLE CAUSES
NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [FS5A-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 the TCC is stuck or the line pressure is low. CAUTION: If the TCC is stuck, inspect it. In addition, inspect the oil cooler for foreign particles which may have mixed in with the ATF. TCC piston slippage, burnt Line pressure high Shift solenoid A malfunction Shift solenoid E malfunction Control valve body malfunction Body ground malfunction Pressure control solenoid A malfunction Signal malfunction VSS malfunction Sensor ground malfunction TFT sensor malfunction APP sensor malfunction Input/turbine speed sensor malfunction Torque converter malfunction NOTE: Before following the troubleshooting steps, make sure that the Automatic Transaxle ON-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

DESCRIPTION & POSSIBLE CAUSES
NO.19 EXCESSIVE SHIFT SHOCK ON TORQUE CONVERTER CLUTCH (TCC) [FS5A-EL]
| 19 | Excessive shift shock on torque converter clutch (TCC) |
|---|
| DESCRIPTION | Strong shock is felt when TCC is engaged. |
| POSSIBLE CAUSE | The troubleshooting flow is the same as the symptom troubleshooting "NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION". (See «NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [FS5A-EL]».) |
