General Description

A malfunction is detected by using a checksum technique for verifying data. The digital data is composed of zeros and ones. A checksum is the total of all ones in a string of data. By comparing the checksum value with a stored value, a malfunction can be detected.

DTC Description

By comparing the checksum value with a stored value in flash ROM, a malfunction can be detected after IG ON.

(MIL : 1 Driving Cycle)

Refer to DTC P0601 : INTERNAL CONTROL MODULE MEMORY CHECK SUM ERROR .

By comparing the checksum value in RAM with a stored value in EEPROM, a malfunction can be detected after IG ON.

(MIL : 1 Driving Cycle)

Refer to DTC P0601 : INTERNAL CONTROL MODULE MEMORY CHECK SUM ERROR .

TCM detects internal RAM value by itself. If the value TCM wrote on RAM differs from the value TCM read, Malfunction can be detected.

(MIL : 1 Driving Cycle)

Inhibitor switch transmits the information which range includes shift lever of A/T to TCM by combination of a position circuit terminal. It is possible for inhibitor switch to start an engine in only P and N (Prevention of reckless driving) and used for inhibitor switch to shift control.

DTC is set if TCM receives multiple signal, more than 2 signal, from the inhibitor switch for 10 seconds. While TCM proceeds final confirm for this fault in its internal process, Shift Lock functions to prevent shifting to Reverse for safety.

(MIL : 1 Driving Cycle)

Refer to DTC P0707 : TRANSMISSION RANGE SENSOR CIRCUIT LOW INPUT .

If TCM has not received any signal from inhibitor switch for 30 seconds, TCM sets DTC. While TCM proceeds final confirm for this fault in its internal process, Shift Lock functions to prevent shifting to Reverse for safety.

(MIL : Consecutive 2 driving cycle)

The automatic TRANSAXLE fluid (ATF) temperature sensor is installed in the Valve Body. This sensor uses a thermistor whose resistance changes according to the temperature changes. The TCM supplies a 5V reference voltage to the sensor, and the output voltage of the sensor changes when the ATF temperature varies. The automatic TRANSAXLE fluid (ATF) temperature provides very important data for the TCM's control of the Torque Converter Clutch, and is also used for many other purposes.

This DTC code is set when the ATF temperature output voltage is not changed for 10 minutes. The TCM regards the ATF temperature as fixed at a value of 80°C (176°F). (MIL : Consecutive 2 Driving Cycle)

Refer to DTC P0711 : TRANSMISSION FLUID TEMPERATURE SENSOR "A" CIRCUIT RANGE/PERFORMANCE .

TCM sets DTC when the ATF temperature sensor signal has been detected over 200°C, voltage is approximately 0V, for 5 minutes. The TCM regards the ATF temperature as fixed at a value of 80°C (176°F) when ATF temperature sensor is faulty.

(MIL : Consecutive 2 Driving Cycle)

Refer to DTC P0711 : TRANSMISSION FLUID TEMPERATURE SENSOR "A" CIRCUIT RANGE/PERFORMANCE .

TCM sets this DTC when ATF temperature sensor has been detected below -43°C (-45.4°F), voltage is approximately 5V, for 12 seconds. The TCM regards the ATF temperature as fixed at a value of 80°C (176°F).

(MIL : 1 Driving Cycle)

Input speed sensor detects input speed from rotation number of direct & reverse disc clutch case. And transmit to TCU as a signal. The TCM determines the input shaft speed by counting the frequency of the pulses. This value is mainly used to control the optimum fluid pressure during shifting.

TCM sets this DTC if signal from input speed sensor is not detected even though vehicle is driving. Fail safe mode is executed if TCM detects this DTC.

(MIL : 1 Driving Cycle)

Output speed sensor detects vehicle speed from rotation number of parking lock gear and transmits to TCU as a signal. This value, together with the throttle position data, is mainly used to decide the optimum gear position.

TCM sets this DTC if output speed sensor signal is not detected even though, vehicle is driving over 30km/h. TCM sets fail safe mode if this DTC is detected. During the TCM internal process to judge this DTC, Shift Lock, which is safety function for controlling to keep neutral when shifting to Reverse by accident, is performed while driving the vehicle over 11 km/h.

(MIL : 1 Driving Cycle)

The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Torque Converter Clutch), to the input shaft of the transmission, by applying hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing the hydraulic load inside the T/C. The PCM/TCM outputs current to control the Torque Converter Clutch Control Solenoid Valve (TCCSV) and hydraulic pressure is applied to the TCC according to the TCC current value. When the amount of current is high, high pressure is applied and the Torque Converter Clutch is locked. The normal operating range of the Torque Converter Clutch Control current value is from 200mA (unlocked) to 1000mA (locked).

TCM increases amount of current, which controls slippage between engine RPM and turbine RPM, in order to engage torque converter clutch.

TCM sets this DTC if Torque converter slippage is not reduced even though TCM controls Torque converter clutch solenoid valve with 1000mA. - It is not the electrical problem but mechanical problem.

(MIL : Consecutive 2 driving cycle)

The TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper Clutch), to the input shaft of the transmission, by applying hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing the hydraulic load inside the T/C. The TCM outputs duty pulses to control the Damper Clutch Control Solenoid Valve (DCCSV) and hydraulic pressure is applied to the DC according to the DCC duty ratio value. When the duty ratio is high, high pressure is applied and the Damper Clutch is locked. The normal operating range of the Damper Clutch Control duty ratio value is from 30% (unlocked) to 85% (locked).

The TCM increases the duty ratio to engage the Damper Clutch by monitoring the slip rpms (difference value between engine speed and turbine speed). If a very small amount of slip RPM is maintained though the TCM applies 0% duty ratio value, then the TCM determines that the Torque Converter Clutch is stuck ON and sets this code.

4 shift solenoid valves are installed directly in valve-body. The solenoids operates of ON and OFF by the control signal from TCU. Combinations of 4 solenoids, S1, S2, S3 and S4, changes gear ranges (1st to 6th)
