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.

Page 13:  · Automatic Transaxle (F4A42) GENERAL AUTOMATIC TRANSAXLE SPECIFICATION ................................................ AT-2 COMPONENTS

A/T CONTROL COMPONENT CHECK

1. THROTTLE POSITION SENSOR CHECK The TPS is a variable resistor type that rotates with the throttle body shaft to sense the throttle valve an­gle. As the throttle shaft rotates, the output voltage of the TPS changes. The ECM detects the throttle valve opening based on voltage change. (Refer to FL-sec­tion).

2. OIL TEMPERATURE SENSOR CHECK

1) Remove the oil temperature sensor.

2) Measure the resistance between terminals 1 and 2 of the oil temperature sensor connector.

TEST PROCEDURE EC52EDF6

TORQUE CONVERTER STALL TEST

EKA9017B

This test measures the maximum engine speed when the selector lever is in the D or R position. The torque con­verter stalls to test the operation of the torque converter, starter motor, one-way clutch operation, the holding per­formance of the clutches, and brakes in the transaxle.

ffi CAUTION

Do not let anybody stand in front of or behind the vehicle while this test is being carried out.

1. Check the automatic transaxle fluid level and temper­ature, and the engine coolant temperature.

• Fluid level : At the HOT mark on the oil level gauge

• Fluid temperature : 80-100°C • Engine coolant temperature : 80-100°C

2. Chock both rear wheels (left and right).

3. Apply the parking brake lever with the brake pedal fully depressed.

4. Start the engine.

5. Move the selector lever to the D position, fully depress the accelerator pedal and take a reading of the maxi­mum engine speed at this time.

ffi CAUTION

a. The throttle should not be left fully open for more than eight seconds.

b. If carrying out the stall test two or more times, move the selector lever to the N position and run the engine at 1,000 rpm to let the auto­matic transaxle fluid cool down before carry­ing out subsequent tests.

Standard value stall speed : 2,100 - 2,900 rpm

AUTOMATIC TRANSAXLE (F4A42)

c. Move the selector lever to the R position and carry out the same test again.

Standard value stall speed : 2,100 - 2,900 rpm

TORQUE CONVERTER STALL TEST JUDGEMENT RESULTS

1. Stall speed is too high in both D and R ranges • Low line pressure • Low & reverse brake slippage

2. Stall speed is too high in D range only • Underdrive clutch slippage

3. Stall speed is too high in R range only • Reverse clutch slippage

4. Stall speed too low in both D and R ranges • Malfunction of torque converter • Insufficient engine output

HYDRAULIC PRESSURE TEST

1. Warm up the engine until the automatic transaxle fluid temperature is 80-100°C.

2. Jack up the vehicle so that the wheels are free to turn.

3. Connect the special tool (oil pressure gauge) to each pressure discharge port.

4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pres­sure table, and check that the measured values are within the standard value ranges.

5. If a value is outside the standard range, correct the problem while referring to the hydraulic pressure test diagnosis table.

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).

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 1st gear ratio, while the transaxle is engaged in the 1st gear. For example, if the output speed is 1000 rpm and the 1st gear ratio is 2.842, then the input speed is 2,842 rpm.

DTC DESCRIPTION E323F0FE

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 1st gear ratio, while the transaxle is engaged in 1st 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, every slippage occur 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 1st 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. Remeasuring is re­

quired.

5. Is "STALL TEST " within specification?

► Go to "Signal Circuit Inspection" procedure.

&I ► Go to "Component inspection" procedure.

& CAUTION • Do not let anybody stand in front of or behind the vehicle while this test is being carried out. • Check the A/T fluid level and temperature and the engine coolant temperature.

Fluid level : At the hot mark on the oil level gauge. Fluid temperature : 1 76 °F- 212 °F (80-100 °C). Engine coolant temperature : 1 76 °F- 212 °F (80-100 °C).

• Chock both rear wheel(left and right). • Pull the parking brake lever on with the brake pedal fully depressed. • The throttle should not be left fully open for more than eight second. • If carrying out the stall test two or more time, move the select lever to the "N" position and run the engine at 1,000 rpm to let the AIT fluid cool down before carrying out subsequent.

REVERSE CLUTCH

BKQE012A

GENERAL DESCRIPTION EE1F4D82

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the reverse gear ratio, while the transaxle is engaged in the reverse gear. For example, if the output speed is 1,000 rpm and the reverse gear ratio is 2.480, then the input speed is 2,480 rpm.

DTC DESCRIPTION E173CE3C

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 reverse gear ratio, while the transaxle is engaged in reverse gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfuctioning rather than an electrical issue.

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.

GENERAL DESCRIPTION

EA7823EF

Underd rive solenoid valve

BKQE013A

The Automatic Transmission changes the gear position of the transmission by utilizing a combination of Clutches and Brakes, which are controlled by solenoid valves. The H IVEC 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 a RED ( Reduction Brake, only for 5 speed transmissions). The LR Brake is engaged in the 1st gear and reverse gear positions.

DTC DESCRIPTION E2CD7361

The TCM checks the Low and Reverse 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 the Low and Reverse control solenoid circuit is malfunctioning and sets this code.

GENERAL DESCRIPTION

EF042F75

E4FD6BD3

Underd rive so lenoid valve

BKQE013A

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 OD Clutch is engaged in the 3rd gear and 4th gear positions.

DTC DESCRIPTION EA3719FE

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 the OVER DRIVE CLUTCH drive control solenoid circuit is malfunctioning and sets this code.
