GS 300 L6-3.0L (2JZ-GE) (1993)
Accumulator: Testing and Inspection
MEASURE ACCUMULATOR BACK PRESSURE
NOTICE:
-
Perform the test at normal operating fluid temperature (50-80°C or 122-176°F).
-
Be careful to prevent the oil pressure gauge hose from interfering with the exhaust pipe.
1. Warm up the transmission fluid.
2. Remove the test plug on the transmission case rear right side and connect the oil pressure gauge (SST).
SST 09992-00094 (Oil pressure gauge)
HINT: Connecting the oil pressure gauge will be made easier by moving the RH side head insulator aside.
3. Remove the passenger side floor carpet and Engine Control Module (ECM) protector.
4. Connect the SST (check harness A) between ECM and connector of vehicle wire harness.
SST: 09990-01000
5. Install one test lead probe into the terminal SLN 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 approximately 8 W light bulb.
