Hydraulic Test

HYDRAULIC TEST

Measure the line pressure.

NOTE:
- Perform the test at the normal operation automatic transmission fluid temperature the 50 to 80 °C (122 to 176 °F)
- The line pressure test should always be carried out in pairs. One technician should observe the conditions of wheels or chocks outside the vehicle while the other is doing the test.
- Be careful to prevent SST's hose from interfering with the exhaust pipe.

1. Warm up the ATF.
2. Remove the test plug on the transaxle case front left side and connect SST (for the location to connect SST).

SST 09992-00095 (09992-00231, 09992-00271)

3. Fully apply the parking brake and chock the 4 wheels.
4. Connect the OBD II scan tool or hand-held tester to the DLC3.
5. Start the engine and check the idling speed.
6. Keep your left foot depressed firmly on the brake pedal and move the shift lever into the D position.
7. Measure the line pressure when the engine is idling.
8. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when the engine speed reaches the stall speed.
9. Perform the test in the R position in the same way.




Specified line pressure:

If the measured pressure does not reach the specified value, recheck the throttle cable adjustment and then retest.
