Test Procedure
- 1. HDS - Connect
- 2. Rear Differential Solenoid Valve - Test (With The HDS)
1. Start the engine
2. Select the FUNCTIONAL TEST in the REAL TIME AWD SYSTEM with the HDS
3. Select the SOLENOID TEST in the FUNCTIONAL TEST with the HDS
4. Do LEVEL 1, then do LEVEL 7 of the SOLENOID TEST in that order with the HDS
5. Check the rear differential solenoid valve for operation with the HDS. A clicking sound should be heard.
- If no clicking sound is heard, replace the rear differential solenoid valve - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD) .
- If a clicking sound is heard, go to the next procedure.
- 3. Vehicle - Lift
- 4. Rear Differential Solenoid Valve - Remove - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD)
- 5. Rear Differential Solenoid Valve - Test
1. Connect a tube (A) to the rear differential solenoid valve (B)
2. Blow the air to the tube.
- If the air flows out of the port, go to step 3.
- If the air does not flow out of the port, replace the rear differential solenoid valve - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD) .
3. Connect a jumper wire from the negative battery terminal to the rear differential solenoid valve body, and connect another jumper wire from the positive battery terminal to connector terminal No. 1 4. Blow the air to the tube.
- If the air flows out of the port, replace the rear differential solenoid valve - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD) .
- If the air does not flow out of the port, the rear differential solenoid valve is OK, and the test is complete.
- 6. Rear Differential Solenoid Valve - Install - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD)
- 7. Rear Differential Fluid - Refill - Refer to: Rear Differential Fluid Inspection and Replacement (4WD) Rear Differential Fluid Inspection and Replacement (AWD)
- 8. Real Time AWD System - Air Bleed
1. Select the ADJUSTMENT in the REAL TIME AWD SYSTEM with the HDS.
2. Select the AIR BLEEDING in the ADJUSTMENT with the HDS.
NOTE: See the HDS Help menu for specific instructions.
- 9. Test Drive - Check
1. Remove the rear differential solenoid valve - Refer to: Rear Differential Disassembly and Reassembly (4WD) Rear Differential Disassembly and Reassembly (AWD) .
