REAR AXLE - On-vehicle Service 27B-21 5. Operate the MUT-II, drive the torque transfer differential (item No.06 and 07) forcibly. (1) Drive the clutch operating mode forcibly for 1 minutes, release the operation automatically. Drive can also be cleared forcibly using the Clear key of MUT-II. (2) If the hydraulic unit function has been stopped by fail-safe, the torque transfer differential cannot be forcibly driven. 6. Operating the MUT-II, by service data (item no.07 and 08), check the condition of the wheel speed below. <Driving item No.06 forcibly> The left rear wheel is faster 2km/h than right rear wheel. <Driving item No.07 forcibly> The right rear wheel is faster 2km/h than left rear wheel. If the above are not satisfied, check the oil pressure as the system may be faulty. OIL PRESSURE CHECK 1. Lift up the vehicle. 2. Set the MUT-II to the 16-pin diagnosis connector. Caution Turn the ignition switch to the LOCK (OFF) position before connecting or disconnecting the MUT-II. 3. Turn the ignition switch to ON. 4. Disconnect the hydraulic unit and the hydraulic unit hose assembly, connect the special tool to L port, put the lid to R port or connect the hydraulic unit hose assembly disconnected from L port to R port. 5. Operating the MUT-II, drive the hydraulic unit forcibly (item No.02). (1) Drive the operation check mode of the clutch left side for 1 minutes, release the operation automatically. Drive can also be cleared forcibly using the Clear key of MUT-II. (2) If the function has been stopped by fail safe, the hydraulic unit cannot be cleared forcibly. 6. Check that the generated oil pressure of the hydraulic unit satisfies the standard value. While the oil pressure is checked, add fluid as necessary to ensure that it is left in the oil reservoir during the entire procedure. 7. Check the oil pressure of the clutch right side following step 4 through 6. Connect the special tool to R port, put the lid to L port or hydraulic unit hose assembly disconnected from R port to L port, use the MUT-II drive item No.07 (operation check mode of clutch right side) forcibly.
