2ND BRAKE
EKBF300B
GENERAL DESCRIPTION
E0E24CF7
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 2nd gear
ratio, while the transaxle is engaged in the 2nd gear. For example, if the output speed is 1000 rpm and the 2nd gear ratio
is 2.442, then the input speed is 2,442 rpm.
DTC DESCRIPTION
E79E971D
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 2nd
gear ratio, while the transaxle is engaged in 2nd gear. This malfunction is mainly caused by mechanical troubles such as
control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
DTC DETECTING CONDITION
E6FA6BCA
Item
Detecting Condition
Possible cause
DTC Strategy
• 2nd gear incorrect ratio
Enable Conditions
• Engine speed >450rpm
• Output speed >500rpm
• After 2sec is passed from shift finish of
shift to 2nd gear
• Input speed > 0rpm
• A/T oil temp > -23.5 C(-9.4 F)
• Voltage of Battery > 10V
• TRANSAXLE RANGE SWITCH is normal
Threshold value
• ㅣ Input speed/2nd gear ratio - output
speed ㅣ ≥ 200rpm
Diagnostic Time
• more than 1sec
Fail Safe
• Locked into 3 rd gear.(If diagnosis code
P0732 is output four times, the transaxle
is locked into 3rd gear)
• Faulty Input speed sensor
• Faulty output speed sensor
• Faulty UD clutch or 2nd brake

Stall test procedure in D2 and reason
Procedure
1.
Warm up the engine.
2.
After positioning the select lever in "D" or "ON" of the HOLD SW ( Operate UP SHIFT in case of "SPORTS
MODE"),depress the foot brake pedal fully after that, depress the accelerator pedal to the maximum.
* The slippage of 2nd gear operating parts can be detected by stall test in D2.
Reason for stall test
1.
If there is no mechanical defaults in A/T, all slippages occurrs in torque converter.
2.
Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel’s lock.
3.
If 2nd brake system(2nd 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?
YES
▶ Go to "Signal circuit inspection" procedure.
NO
▶ Go to "Component inspection" procedure.
CAUTION
1.
Do not let anybody stand in front of or behind the vehicle while this test is being carried out.
2.
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 : 176 F~ 212 F (80~100 C).
• Engine coolant temperature : 176 F~ 212 F (80~100 C).
3.
Chock both rear wheel(left and right).
4.
Pull the parking brake lever on with the brake pedal fully depressed.
5.
The throttle should not be left fully open for more than eight second.
6.
If stall test is being performed more than once, move the selector lever to ’N’ and run the engine at 1000
RPM to allow the transaxle fluid to cool prior to subsequent tests.
