Fig. 163: Connecting Pressure Gauge To The Differential 6. Connect the pressure gauge (C) to the adapter, and install the assembly into the differential (B). Route the hose under the vehicle toward the front door. 7. Do the acceleration device test. When you get to the "Keep the speed constant between 22 and 28 mph" screen in the test, write down the pressure indicated on the pressure gauge. Complete the test. If the hydraulic pressure was over 8.0 kg/cm 2 , go to step 8.
If the hydraulic pressure was below 8.0 kg/cm 2 , replace the rear differential center case.
8. Replace the shift solenoid. 9. Do the acceleration device test. If Normal is displayed, the problem has been fixed. If the acceleration ratio is higher than the normal value when accelerating is displayed, replace 10. Check the differential oil level. If the oil level was low, add oil as needed, then go to step 12. If the oil level was OK, go to step 11. 11. Do the acceleration device test. After the shift solenoid test (a portion of the acceleration device test) is complete, continue the acceleration device test. When you get to the "Keep the speed constant If the hydraulic pressure was less than 8.0 kg/cm 2 , go to step 12.
If the hydraulic pressure was over 8.0 kg/cm 2 , replace the rear differential assembly.
12. Do the acceleration device test. Look at the results displayed on the HDS. If Normal is displayed, the problem has been fixed. If "Acceleration device is abnormal" is displayed, go to step 13. 13. Replace the shift solenoid, then do the acceleration device test. If Normal is displayed, the problem has been fixed. If "Acceleration device is abnormal" is displayed, replace the rear differential assembly. REAR DIFFERENTIAL FLUID INSPECTION AND REPLACEMENT INSPECTION
