Function Inspection
Function inspection1. Check of shift lock operation
(1) Shift the select lever to the P position.
(2) Check that the select lever cannot be shifted to ranges other than P position when it is operated.
(3) Check that the select lever can be shifted to ranges other than P position with IG ON and the brake pedal depressed.
2. Check of shift lock release button operation
(1) Check that the select lever can be shifted to ranges other than P position when it is operated with the shift lock release button pressed.
3. Time lag check
CAUTION:
^ Always perform the inspection after the engine check and adjustment.
^ Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
^ Perform the inspection with the A/C OFF.
(1) Apply the parking brake and set the wheel stoppers.
(2) Start the engine.
(3) Shift from N position to D or R position with idling while depressing the brake pedal, and measure the time until a small shock is felt.
Standard value: N->D position 1.2 seconds or less
N->R position 1.5 seconds or less
CAUTION:
^ Make measurements 3 times and take the average value.
^ Allow 1 minute interval when performing consecutive measurements.
4. Stall speed check
CAUTION:
^ Always perform the inspection after the engine check and adjustment.
^ Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
^ Perform the inspection with the A/C OFF.
^ Do not perform the operation continuously for 5 seconds or more. (Working time for the sequence from the accelerator full close, full open, stall speed reading, to the accelerator full close)
^ Perform in a place with high friction coefficient such as on asphalt to prevent the tires from spinning.
^ After performing the stall test, be sure to cool down the engine for at least 1 minute with the select lever set in P or N position, and at an idle speed of 1200 rpm or less.
^ If the stall speed is higher than the specified range, finish the stall test in as short a time as possible, in order to prevent the automatic transmission from being damaged.
^ Perform the stall test in normal mode.
(1) Firmly apply the parking brake and set the wheel stoppers.
(2) Start the engine.
(3) Firmly depress the parking brake with left foot, shift to D position, and quickly read the maximum engine speed when the accelerator pedal is fully depressed with right foot.
Standard value
5. Line pressure check
CAUTION:
^ Wash the equipment and hoses with white gasoline before and after measurement.
^ Always perform the inspection after the engine check and adjustment.
^ Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
^ Perform the inspection with the A/C OFF.
^ Do not perform the inspection continuously for 5 seconds or more at stall. (Working time for the sequence from the accelerator full close, full open, stall speed reading, to the accelerator full close)
^ After performing the stall test, be sure to cool down the engine for at least 1 minute with the select lever set in P or N position, and at an idle speed of 1200 rpm or less.
^ If the stall speed is higher than the specified range, finish the stall test in as short a time as possible, in order to prevent the automatic transmission from being damaged.
^ Perform the stall test in normal mode.
(1) Remove the under cover No.1.
(2) Remove the under cover No.2.
(3) Remove the exhaust pipe ASSY FR.
(4) Attach the SST on the transmission.
SST 18681AA040, 498897700, 498575400
CAUTION:
^ Use 18681AA040 with genuine O-ring (17006AA000) attached.
^ Route the hose so that it does not contact the exhaust pipe.
Captions in illustration
(5) Install the exhaust pipe ASSY FR.
(6) Firmly apply the parking brake and set the wheel stoppers.
(7) Start the engine.
(8) Firmly depress the brake pedal with left foot and shift to D or R position, then check the hydraulic pressure at idling and stalling.
Standard value
NOTE:
When there is an open or short circuit in the line pressure control solenoid ASSY (SLT) system, the line pressure reaches the maximum.
6. Shift table
WARNING:
Observe the legal speed limit and confirm the safety on the road.
CAUTION:
^ Always perform the inspection after the engine check and adjustment.
^ Perform the inspection at an oil temperature (40 to 110°C {104 to 230°F}) in normal driving temperature.
^ Perform the inspection at an engine coolant temperature of 60 to 90°C {140 to 194°F}.
^ Turn the A/C and the cruise control OFF.
NOTE:
^ The values equal to or higher than the maximum speed are for reference because they cannot be achieved.
^ Do not shift to 6th gear when the AT oil temperature is less than 20°C {68°F}.
^ Lockup is prohibited when the AT oil temperature is less than 20°C {68°F}.
^ Lockup does not occur at 1st gear of manual mode.
^ Acceleration slipping lock-up is prohibited when the AT oil temperature is less than 40°C {104°F} or 110°C {230°F} or more.
^ Reduction slipping lock-up is prohibited when the AT oil temperature is less than 20°C {68°F} or 110°C {230°F} or more.
(1) Shift table
(a) Use SSM3 to select [Current Data Display & Save]->[Normal sampling], and then select [AT Speed], [Control the Shift Position], [Accel. Opening Angle], [A/T Oil Temperature], and [Coolant Temp].
(b) Confirm [AT Speed] when [Control the Shift Position] is up-shifted.
(2) Lock-up
(a) Use SSM3 to select [Current Data Display & Save]->[Normal sampling], and then select [AT Speed], [Control the Shift Position], [Accel. Opening Angle], [Engine Speed], [Turbine Revolution Speed], [Coolant Temp.], and [Lock up status].
(b) Confirm that the difference between [Engine Speed] and [Turbine Revolution Speed] is 50 r/min or less.
(3) Manual downshift permission vehicle speed
7. Driving test
WARNING:
Observe the legal speed limit and confirm the safety on the road.
CAUTION:
^ Always perform the inspection after the engine check and adjustment.
^ Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
^ Turn the A/C and the cruise control OFF.
