DIAGNOSIS FUNCTION
1. Connect the Hi Scan Pro to the connector for diagnosis.
2. Read the output diagnostic trouble codes. Then follow the remedy procedures according to the "DIAGNOSTIC TROUBLE CODE DESCRIPTION" on the following pages.
NOTE
• A maximum of 8 diagnostic trouble codes (in the sequence of occurrence) can be stored in the Random Access Memory (RAM) incorporated within the control module.
• The same diagnostic trouble code can be stored one time only
• If the number of stored diagnostic trouble codes or diagnostic trouble patterns exceeds 8, already stored diagnostic trouble codes will be erased in sequence, beginning with the oldest.
• Do not disconnect the battery until all diagnostic trouble codes or diagnostic trouble patterns have been read out, because all stored diagnostic trouble codes or diagnostic trouble patterns will be cancelled when the battery is disconnected.
3. If the fail-safe system is activated and the transaxle is locked in third gear, the diagnostic trouble code in the Fail-safe code description will be stored in the RAM. Three of these diagnostic trouble codes can be stored.
4. The cancellation will occur if, with the transaxle locked in third gear, the ignition key is turned to the OFF position, but the diagnostic trouble code is stored in the RAM.
5. Memorization. • Up to 8 diagnosis items and 3 fail-safe items can
be memorized. • If the memory capacity is exceeded, diagnosis
and fail-safe items in the memory are overwritten, starting with the oldest.
• No code can be memorized more than once.
AT-5
6. Diagnosis Code Deletion.
1) Automatic Deletion All diagnosis codes are deleted from memory the 200 th time the ATF temperature reaches 50°C after memorization of the most recent diagnosis code.
2) Forced Deletion Memorized diagnosis codes can be deleted using the scan-tool, provided the following conditions are satisfied
• The ignition switch is ON • There is no detection pulse from the crank
angle sensor • There is no detection pulse from the output
shaft speed sensor • There is no detection pulse from the vehicle
speed sensor • The fail-safe function is not operational

SERVICE ADJUSTMENT
PROCEDURE E73F5727
AUTOMATIC TRANSAXLE FLUID CHECK
1. Drive the vehicle until the fluid temperature rises to the normal temperature (70~80°C).
2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque converter and the hydraulic circuits with fluid, and then move the selector lever to the N position.
4. After wiping off any dirt around the oil level gauge, reinsert and remove the oil level gauge and check the condition of the fluid.
, NOTE
If the fluid smells as if it is burning, it means that the fluid has been contaminated by fine particles from the bushes and friction materials, a transaxle overhaul may be necessary.
5. Check that the fluid level is at the HOT mark on the oil level gauge. If the fluid level is lower than this, add more fluid until the level reaches the HOT mark. Automatic transaxle fluid : DIAMOND ATF SP-Ill., SK ATF SP-Ill.
, NOTE
If the fluid level is low, the oil pump will draw in air along with the fluid, which will cause bubbles to form inside the hydraulic circuit. This will in turn cause the hydraulic pressure to drop, which will result in late shifting and slipping of the clutches and brakes. If there is too much fluid, the gears can churn it up into foam and cause the same conditions that can occur with low fluid levels. In either case, air bubbles can cause overheating and oxidation of the fluid which can interfere with normal valve, clutch, and brake operation. Foaming can a/so result in fluid escaping from the transaxle vent, in which case it may be mistaken for a leak.
6. Insert the oil level gauge securely.
7. The fluid and the oil filters should always be replaced when overhauling the transaxle or after the vehicle has been driven under severe conditions. The replacement procedures are given below. Furthermore, the oil filters are special filters which are only to be used for the automatic transaxle.
AUTOMATIC TRANSAXLE (F4A42)
NOTE
When new, automatic transmission fluid should be red. The red dye is added so distinguish it from engine oil or antifreeze. As the vehicle is driven the transmission fluid will begin to look darker. The color may eventually appear light brown Also, the dye, which is not an indicator of fluid quality, is not permanent Therefore, further investigation of the automatic transaxle is required if,
• the fluid is dark brown or black. • the fluid smells burnt. • metal particles can be seen or felt on the dipstick.
AUTOMATIC TRANSAXLE FLUID
REPLACEMENT
If you have a fluid changer, use this changer to replace the fluid. If you do not have a fluid changer, replace the fluid using following procedure.
1. Remove the drain plug from the bottom of the transaxle case to drain the fluid.
2. Install the drain plug and gasket, and tighten to the specified torque.
Tightening torque : 32 Nm (320 kgf-cm, 23 lbf-ft)
3. Pour the new fluid in through the oil filler tube.
. ! CAUTION
Stop pouring if the full volume of fluid cannot be poured in.
4. Repeat the procedure in step 1 if too much fluid was added.
5. Reconnect the hose that was disconnected in step 1 above, and firmly replace the oil level gauge.
6. Start the engine and run it at idle for 1-2 minutes.
7. Move the select lever through all positions, and then move it to the N position.
8. Drive the vehicle until the fluid temperature rises to the normal temperature (70~80°C), and then check the fluid level again. The fluid level must be at the HOT Mark.

COMPONENT LOCATION EE518085
ELQE043A
GENERAL DESCRIPTION EDAE3CF6
The automatic T RANSAXLE fluid(AT F) 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 AT F temperature varies. The automatic T RANSAXLE fluid(AT F) temperature provides very important data for the T CM's control of the Torque Converter Clutch, and is also used for many other purposes.
DTC DESCRIPTION EE6EFE6A
This DT C code is set when the ATF temperature output voltage is lower than a value generated by thermistor resistance, in a normal operating range, for approximately 1 second or longer. The TCM regards the ATF temperature as fixed at a value of 80°C(176°F).

GENERAL DESCRIPTION EC8A28C6
The Output Speed Sensor outputs pulse-signals according to the revolutions of the output shaft of the transmission. The Output Speed Sensor is installed in front of the Transfer Drive Gear to determine the Transfer Drive Gear rpms by counting the frequency of the pulses. This value, together with the throttle position data, is mainly used to decide the optimum gear position.
DTC DESCRIPTION E3F92066
The TCM sets this code if the calculated value of the pulse-signal is noticeably different from the value calculated, using the Vehicle Speed Sensor output, when the vehicle is running faster than 30 km/h. The TCM will initiate the fail safe function if this code is detected.

GENERAL DESCRIPTION EDBF3B4A
BKQE008A
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 3rd gear ratio, while the transaxle is engaged in the 3rd gear. For example, if the output speed is 1,000 rpm and the 3rd gear ratio is 1.000, then the input speed is 1,000 rpm.
DTC DESCRIPTION E1BF7CC6
This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the 3rd gear ratio, while the transaxle is engaged in 3rd gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfuctioning rather than an electrical issue.

Reason for stall test 1. If there is no mechanical defaults in A/T, all slippage occurs in torque converter. 2. Therfore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock. 3. If OD clutch system(3rd gear operating part) has faults, input speed revolution will be out of specification. 4. If output speed revolution is output. It means that the foot brake force is not applied fully. Retesting using greater
braking force is required.
5. Is "STALL TEST " within specification?
► Go to "Signal Circuit Inspection" procedure.
► Go to "Component Inspection" procedure.

I DTC P0741 TORQU E CONVERTER CLUTCH C IRCUIT - STUCK OFF
GENERAL DESCRIPTION EF781BCE
The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper Clutch), to the input shaft of the transmission, by appling hydraulic pressure. The main purpose of TIC clutch control is to save fuel by decreasing the hydraulic load inside the TIC. The PCM/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%(Iocked).
DTC DESCRIPTION EE0F54F4
The PCM/TCM increases the duty ratio to engage the Damper Clutch by monitoring slip rpms (difference vlaue beteween engine speed and turbine speed). To decrease the slip of the Damper Clutch, the PCM/TCM increases the duty ratio by appling more hyraulic pressure. When slip rpm does not drop under some value with 100% duty ratio, the PCM/TCM determines that the Torque Converter Clutch is stuck OFF and sets this code.

The Automatic Transmission changes the gear position of the transmission utilizing a combination of Clutches and Brakes, which are controlled by solenoid valves. The HIVEC Automatic Transmission consists of a: LR ( Low and Reverse Brake ), 2ND ( 2nd Brake ), UD ( Under Drive Clutch ), OD ( Over Drive Clutch ), REV ( Reverse Clutch ), and RED ( Reduction Brake, only for 5 speed transmissions). The 2ND Brake is engaged in the 2nd gear and 4th gear positions.
DTC DESCRIPTION EBEA6BE9
The TCM checks the Under Drive Clutch Control Signal by monitoring the feedback signal from the solenoid valve drive circuit .If an unexpected signal is monitored, ( For example, high voltage is detected when low voltage is expected or low voltage is detected when high voltage is expected) the TCM judges that 2nd Brake drive contorl solenoid circuit is malfunctioning and sets this code.

The vehicle speed sensor outputs pulse-signals according to the revolutions of the output shaft of the transmission. The TCM determines the vehicle speed by counting the frequency of the pulses. This value is mainly used, by the TCM, as comparison data for determining malfunctions of the OUT PUT SPEED SENSOR.
DTC DESCRIPTION E0AE3FAE
The T CM calculates the vehicle speed based on the frequency of the pulses. If the calculated value from this sensor does not agree with the value determined by the OUT PUT SPEED SENSOR(PGB) , the TCM sets this code.
