Measure Accumulator Back Pressure

NOTE:
- Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176 °F).
- Be careful to prevent SST's hose from interfering with the exhaust pipe.

a. Warm up the ATF.

b. Remove the test plug on rear right side of the transmission case and connect SST.
SST 09992-00095 (09992-00151, 09992-00271)

HINT: The connection of SST will become easier by moving the RH side heat insulator aside. (See page the location to connect SST)

c. Remove the passenger side floor carpet and ECM protector.

d. Insert one test lead probe into the terminal SLN 6| of the ECM wire harness side connector and take care not to ground the other test lead probe.






HINT: Prepare test leads which are connected with an 8 W light bulb.

e. Fully apply the parking brake and chock the 4 wheels.
f. Start the engine and check idling speed.
g. Keep your left foot pressing firmly on the brake pedal and shift into D position.
h. Measure the accumulator back pressure.




i. In the same conditions as in (h), ground the other probe of the test lead which has one end inserted into the terminal SLN-of the ECM harness side connector, then measure the accumulator back pressure again.
