Kia Carens. Manual — part 158
1. Start engine.
2. Check idle speed in P range, refer to emission control system.
Idle speed : 750~850 rpm (with parking brake applied)
3. Shift from N range to D range.
4. Use a stopwatch to measure time it takes from shifting until shock is felt.
5. Shift selector to N range and run engine at idle speed for at least one minute.
Make three measurements for each test and take average value.
6. Perform test for following shifts in same manner.
A. N → D range
B. N → 2 range
C. N → R range
Time lag : N → D range 0.5~0.6 second
Time lag : N → R range 0.6~0.7 second
Evaluation of time lag test
Condition
Possible cause
N→D shift
More than specification
Insufficient line pressure
Forward clutch slipping
One-way clutch No. 1 slipping
One-way clutch No. 2 slipping
Less than specification
N/D accumulator not operating properly
Excessive line pressure
N→2 range
More than specification
Excessive line pressure
Insufficient line pressure
Forward clutch slipping
2-4 brake band slipping
One-way clutch No. 1 slipping
Less than specification
1-2 accumulator not operating properly
Excessive line pressure
N→R shift
More than specification
Insufficient line pressure
Low and reverse brake slipping
Reverse clutch slipping
Less than specification
N/R accumulator not operating properly
Excessive line pressure
Line pressure test
This test measures line pressure as a means of checking hydraulic components and inspecting for oil leakage.
Preparation
1. Perform preparation procedure outlined in Stall Test.
2. Remove splash shield under front left bumper.
3. Connect SST (0K201 190 AA0) to line pressure inspection port (square-head "L" plug). It may be necessary to raise
car to get at inspection port.
Procedure
1. Start engine.
2. Check idle speed in P range, refer to emission control.
Idle speed : 750~850 rpm (with parking brake applied)
3. Shift selector lever to D range and read line pressure at idle.
Perform steps 4 and 5 within 5 seconds to prevent possible transaxle damage.
4. Depress brake pedal firmly with left foot and gradually depress accelerator pedal fully with the right foot.
5. Read line pressure as soon as engine speed becomes constant and release accelerator pedal.
Idling for at least one minute cools ATF and prevents deterioration.
6. Shift selector lever to N range and run engine at idle for at least one minute.
7. Read line pressure at idle and at engine stall speed for each range in same manner.
Specified line pressure
Range
Idle
Stall
D, 2, 1
56.98~127.98 (392.4~882.9, 4.0~9.0)
113.76~184.86 (784.8~1275.3, 8.0~13.0)
R
71.1~142.2 (490.5~981.5, 5.0~10.0)
199.08~270.18 (1373.4~1863.9, 14.0~19.0)
8. Install a new square-head "L" plug in inspection port, refer to line pressure test.
Tightening torque : 44~86 lb-in (5.0~9.8 N·m, 51~100 kg-cm)
Evaluation of line pressure test
Line pressure
Possible location of problem
Low pressure in every position
Worn oil pump
Fluid leaking from oil pump, control valve, or transaxle
case
Pressure regulator valve sticking
Linear solenoid valve sticking
Low pressure in D and 2 only
Fluid leaking from hydraulic circuit of forward clutch
Low pressure in R only
Fluid leaking from hydraulic circuit of low and reverse
brake or reverse clutch
Higher than specification
Pressure regulator valve stick or Linear solenoid valve
sticking
Road test
Preparation
1. Check and correct (as necessary) engine coolant, engine oil and ATF levels before testing.
2. Warm up engine thoroughly to raise ATF temperature to an operating level of 140~158°F (60~70°C).
3. Check idle speed and ignition timing in P position.
D range (Power mode)
1. Turn O/D switch from OFF to ON.
2. Quickly depress accelerator pedal fully, and verify that 1↔2, 2↔3 and 3↔4 upshift and downshift are obtained.
The shift points must be as shown in graph below.
3. Drive vehicle in third and second gear and verify that kickdown occurs for 4↔3, 3↔2, 2↔1 and that the shift points
are as shown in graph below
The torque converter clutch will not operate in following conditions :
1) The engine coolant temperature is below 144°F (62°C).
2) The closed throttle position switch is ON.
3) The brake switch is ON.
The transaxle fluid temperature is over 262°F (128°C) the torque converter clutch will operate in 3nd gear and 4th
gear.
D range (Econo mode)
1. Turn O/D switch from ON to OFF.
2. Gradually depress accelerator pedal, and verify that 1↔2, 2↔3 and 3↔4 upshift and downshift are obtained.
The shift points must be as shown in graph below.
3. Drive vehicle in third and second gear and verify that kickdown occurs for 4↔3, 3↔2, 2↔1 and that the shift points
are as shown in graph below.
The economic mode will not activate in the case that the engine temperature is bellow 114°F (62°C)
