(1) Warm up the ATF.
(2) Lift the vehicle.
(3) Remove the engine under cover.
(4) Remove the test plug A on the front side of the transaxle case and install SST.

(5) Lower the vehicle.
(6) Fully apply the parking brake and chock all 4 wheels.
HINT:
When the electric parking brake switch assembly is pulled 2 times (2 lock operations), the maximum amount of braking force is applied.
(7) Start the engine and check the idle speed.
(8) Keep your left foot firmly on the brake pedal and move the shift lever to D.
(9) Measure the line pressure with the engine idling.
(10) Depress the accelerator pedal as much as possible with your right foot. Quickly read the highest line pressure reading when the engine speed reaches stall speed.
Specified Line Pressure Condition | D Position |
---|---|
Idling | 420 to 510 kPa (4.2 to 5.3 kgf/cm2, 60 to 74 psi) |
Stall test | 1560 to 1750 kPa (15.9 to 17.9 kgf/cm2, 226 to 254 psi) |
(11) Turn the engine switch off.
(12) Remove SST and install the test plug A.
(13) Remove the test plug B on the left side of the transaxle case and install SST.

(14) Start the engine and check the idle speed.
(15) Keep your left foot firmly on the brake pedal and move the shift lever to R.
(16) Measure the line pressure with the engine idling.
(17) Depress the accelerator pedal as much as possible with your right foot. Quickly read the highest line pressure reading when the engine speed reaches stall speed.
Specified Line Pressure Condition | R Position |
---|---|
Idling | 560 to 670 kPa (5.7 to 6.9 kgf/cm2, 81 to 98 psi) |
Stall test | 1750 to 2050 kPa (17.8 to 21.0 kgf/cm2, 253 to 298 psi) |
(18) Turn the engine switch off.
(19) Remove SST and install the test plug B.
(20) Clear the DTCs.
