HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
CAUTION:
The line pressure test should always be performed with at least 2 people. One person should observe the condition of the wheels and wheel chocks while the other is performing the test.
NOTICE:
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Turn the ignition switch off.
(3) Lift the vehicle up.
(4) Remove the test plug from the transmission case and connect SST.
SST: 09993-19015
09993-00010
09993-00040
(5) Lower the vehicle.
(6) Fully apply the parking brake and chock the 4 wheels.
(7) Start the engine and check the idling speed.
(8) Keep your left foot pressed firmly on the brake pedal and move the shift lever to D.
(9) Fully depress the accelerator pedal with your right foot. Quickly read the highest line pressure when the engine speed reaches the stall speed.
(10) In the same manner, perform the test with the shift lever in R.
Specified Line Pressure
Condition |
D Position |
R Position |
---|---|---|
Stall speed |
1450 to 1740 kPa (14.8 to 17.7 kgf/cm2, 210 to 252 psi) |
1550 to 1840 kPa (15.8 to 18.8 kgf/cm2, 225 to 267 psi) |
Problem |
Possible Cause |
---|---|
Measured values are higher than the specified value in all positions |
|
Measured values are lower than the specified value in all positions |
|
Pressure is low in D position only |
|
Pressure is low in R position only |

Acceleration Sensor Stuck Malfunction (C1232,C1243,C1245)
DESCRIPTION
The skid control ECU (brake actuator assembly) receives signals from the yaw
rate and acceleration sensor (airbag sensor assembly) via the CAN communication
system.
The airbag sensor assembly has a built-in acceleration sensor and detects the
vehicle condition.
If there is troub ...
