Hydraulic Pressure Tests

HYDRAULIC PRESSURE TEST





1. Completely warm up the transaxle.
2. Raise the vehicle by using a jack so that the drive wheels can be rotated.
3. Connect an engine tachometer and place it in a position where it's easy to see.
4. Attach the special oil-pressure gauge (MD998330, MD999563) and the adapter (MD998332) to each oil-pressure outlet port.
When the reverse position pressure is to be tested, the 3,000 kPa (435 psi) type of gauge should be used.





5. Measure each hydraulic pressure under the conditions in the standard hydraulic pressure table, and check that they are at the standard values.
6. Use the scan tool to force-drive the actuator, and measure the kickdown brake pressure (Apply) when the Pressure Control Solenoid Valve (PCSV) is at 50 % duty.

NOTE:
1. Vehicle speed: 0 km/h (0 mph)
2. Selector lever switch position: "ID"
3. Accelerator condition: Fully closed.

If all of the above conditions are fulfilled, activate the actuator for 5 seconds to bring the PCSV to 50% duty.








7. If the pressure is outside the standard value, repair according to the hydraulic pressure test diagnosis chart.

NOTES:
- Must be 10 kPa (1.5 psi) or less.
SW-ON: Switch ON the overdrive control switch.
SW-OFF: Switch OFF the overdrive control switch.
* Hydraulic pressure is generated, but not the standard value.
