Replaced Part or Performed Procedure

Necessary Procedure

Effect/Inoperative Function when Necessary Procedure not Performed

Link

Replacement of 4WD linear solenoid (transmission coupling assembly)

ECU data write

Active torque split AWD system

Gas leaks from exhaust system

Inspection after repair

  • Poor idle, etc.
  • Engine start function, etc.

Rear wheel alignment adjustment

Calibration

  • DTCs are stored
  • Slip indicator light illuminates
  • VSC disabled or malfunctions

CAUTION:

  • To prevent burns, do not touch the engine, exhaust pipe or other high temperature components while the engine is hot.
  • The rear differential carrier assembly is very heavy. Be sure to follow the procedure described in the repair manual, or the engine lifter may suddenly drop or the rear differential carrier assembly may fall off the engine lifter.

6. REMOVE REAR DIFFERENTIAL CARRIER ASSEMBLY

NOTICE:

  • Do not damage the contact surface when removing the rear differential carrier assembly.
  • The remaining oil may leak out when removing the rear differential carrier assembly.
  • Securely support the rear differential carrier assembly while performing this step to avoid excessively tilting or dropping the rear differential carrier assembly.
  • Remove the bolts and nuts with the rear differential carrier assembly secured.

(a) Disconnect the vacuum hose from the electro magnetic control coupling sub-assembly.

(b) Support the rear differential carrier assembly with an engine lifter using 2 attachments or equivalent tools as shown in the illustration.

Clamp (A)

*b

Clamp (B)

(g) Separate the vacuum hose from the clamp (B).

(h) Slightly lower the rear differential carrier assembly, remove the vacuum hose from the clamp.

NOTICE:

Do not damage the vacuum hose and electro magnetic control coupling wire harness.

HINT:

Lower the engine lifter to the extent that the vacuum hose can still be removed.

*1

Vacuum Hose

(i) Lower the rear differential carrier assembly slowly to remove the rear differential carrier assembly.

NOTICE:

  • Do not damage the vacuum hose and electro magnetic control coupling wire harness.
  • Move the engine lifter forward and backward as necessary to prevent the rear differential carrier assembly from contacting the rear suspension member sub-assembly.

7. REMOVE REAR UPPER DIFFERENTIAL MOUNT STOPPER

(a) Remove the 2 rear upper differential mount stoppers from the rear No. 1 differential support.

8. REMOVE REAR DIFFERENTIAL DYNAMIC DAMPER

(a) Remove the 2 bolts and rear differential dynamic damper from the rear differential support.

9. REMOVE REAR DIFFERENTIAL SUPPORT

(a) Remove the 3 bolts and rear differential support from the rear differential carrier assembly.

    DESCRIPTION The air fuel ratio sensor (sensor 1) generates current that corresponds to the actual air fuel ratio. This sensor current is used to provide the ECM with feedback so that it can control the air fuel ratio. The ECM determines the deviation from the stoichiometric air fuel ratio level, and regulates the fuel injection duration...
