SYMPTOM TROUBLESHOOTING [AW6A-EL, AW6AX-EL] 05-03–19 05-03 End Of Sie NO.13 NO KICKDOWN[AW6A-EL, AW6AX-EL] id050310801800 End Of Sie NO.14 ENGINE FLARES UP OR SLIPS WHEN UPSHIFTING OR DOWNSHIFTING[AW6A-EL, AW6AX-EL] id050310801900 3 • Inspect the line pressure control solenoid. (See 05-17-20 SOLENOID VALVE • Is the line pressure control solenoid normal? Yes Go to the next step. No Replace the control valve body. 4 • Remove the torque converter. (See 05-17-46 TORQUE CONVERTER • Inspect the torque converter. • Is the torque converter normal? Yes Inspect the ATF condition. • If a large amount of metal specks are found, replace the transaxle. • If a large amount of metal specks are not found, replace the control valve body. No Replace the torque converter. 5 • Verify test results. — If normal, return to the diagnostic index to service any additional symptoms. — If malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis. • If the vehicle is repaired, troubleshooting completed. • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM. STEP INSPECTION ACTION 13 No kickdown DESCRIPTION • Does not downshift when accelerator pedal is fully depressed within kickdown range. POSSIBLE CAUSE • If transaxle does not downshift though shifting is normal, the malfunction is in the accelerator pedal position sensor and accelerator pedal position sensor circuits (including sensor GND, sensor wiring 14 Engine flares up or slips when upshifting or downshifting DESCRIPTION • When the accelerator pedal is depressed for acceleration from standstill, engine speed increases but the vehicle speed increases slowly. • When the accelerator pedal is depressed while driving, engine speed increases but the vehicle speed does not. POSSIBLE CAUSE • There is clutch slippage because the clutch is stuck or the line pressure is low. — Clutch stuck, slippage (C1 clutch, C2 clutch, C3 clutch, B1 brake) • Line pressure low • Incorrect accelerator opening signal • VSS malfunction • Input/turbine speed sensor malfunction • Sensor GND malfunction • Shift solenoid C malfunction • Shift solenoid D malfunction • Shift solenoid E malfunction • Line pressure control solenoid malfunction • TCC control solenoid malfunction • Shift solenoid F malfunction • Body GND malfunction • Control valve body malfunction Note • Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.
