Hydraulic Test

U760E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: HYDRAULIC TEST

1. PERFORM HYDRAULIC TEST

(a) Measure the line pressure.

CAUTION:
The line pressure test should always be carried out 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:
* Perform the test while the ATF temperature is 50 to 80°C (122 to 176°F).
* Be careful to prevent the hose of SST from interfering with the exhaust pipe.
* This check must be conducted after checking and confirming that the engine is normal.
* Perform the test with the A/C off.
* Do not perform the stall test for more than 5 seconds.

(1) Warm up the ATF.

(2) Turn the ignition switch off.

(3) Lift the vehicle up.

(4) Remove the test plug from the transaxle case and connect SST.

(8) Start the engine.

(9) Enter the following menus: Powertrain / ECT / Active Test / Control the Shift Position.

(10) Move the shift lever to D, and then use the Techstream to hold 3rd gear using the Active Test. Measure the line pressure while the engine is idling.

Specified Line Pressure





(11) Turn the ignition switch off.

(12) Disconnect the connector of the TCM.

HINT
Disconnect the connector only when performing the D position stall test.

(13) Start the engine.

(14) Firmly depress the brake pedal, move the shift lever to D, depress the accelerator pedal all the way down and check the line pressure while the stall test is performed.

Specified Line Pressure





(15) Turn the ignition switch off.

(16) Connect the TCM connector, depress the brake pedal firmly, move the shift lever to R and check the line pressure while the engine is idling and during the stall test.

Specified Line Pressure





(17) Remove SST and install the test plug.

(18) Clear the DTCs.
