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, 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 Transaxle fluid temperature sensor Vehicle speed sensor Input/turbine speed sensor Sensor GND Output solenoid valve system malfunction (Sticking) Shift solenoid E malfunction Shift solenoid A malfunction Control valve body malfunction system (Poor operation, stuck) TCC hydraulic pressure system TP sensor malfunction (Not operating linear) Accelerator pedal position sensor malfunction (Not operating linear) Input/turbine speed sensor or vehicle speed sensor 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 «BASIC INSPECTION [FN4A-EL]» ). |

DESCRIPTION AND POSSIBLE CAUSES
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 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. Torque converter clutch piston slippage, burnt Line pressure high Shift solenoid A malfunction Control valve body malfunction Body GND malfunction Pressure control solenoid malfunction Signal malfunction Vehicle speed sensor malfunction Sensor GND malfunction TFT sensor malfunction TP sensor malfunction or mis-adjustment Accelerator pedal position sensor malfunction or mis-adjustment 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. (See «BASIC INSPECTION [FN4A-EL]» ). |
