Hydraulic Pressure Test

HYDRAULIC PRESSURE TEST
Hydraulic pressure test is used to indirectly check the normal operation of fluid pump and piston oil seal of each element by measuring operating pressure of each element in case of transaxle shock or slip.
If will be required to perform basic checks and inspect the electronic control system before testing the hydraulic pressure.

PROCEDURE
1. Warm up the ATF to 70 - 80°C (158 - 176°F).
2. Suspend the vehicle to idle wheels.
3. Install the special tools: fluid pressure gauge 2943 kPa (30 kgf/cm2, 426.6 psi) and adapter (RED, DIR pressure) at each fluid pressure outlet.
4. Measure fluid pressure at each outlet and compare it with standard value referring to standard fluid pressure table.
5. If the pressure deviates from standard value, take corrective measure referring to fluid pressure test diagnosis chart.
