3. Hold the rear wheel hub assembly in a vice using wooden blocks.
4. Measure the wheel bearing rotation starting torque by using special tools
MB990326 and MB990685.
Limit: 1.4 N.m (1.03 ft-lb)
5. If the rotation starting torque is not within the limit range when the nut is
tightened to 236 +/- 19 N.m (174 +/- 14 ft-lb), replace the front wheel bearing
assembly. If there is any signs of binding or tight spots when the wheel bearing
turns, replace it.
6. Measure to determine whether the wheel bearing axial play is within the
specified limit or not.
Limit: 0.05 mm (0.002 inch)

CAUTION: For AWD-vehicles, never subject the wheel bearings
to the vehicle load when the drive shaft nuts, or the
special tool (MB991004) is loosened.
NOTE: For AWD-vehicles, attach the camber/caster/kingpin gauge
to the drive shaft by using the special tool MB991004.
Tighten special tool MB991004 to the same torque 230 +/- 30
N.m (170 +/- 21 ft-lb) as the drive shaft nut.

EXAMPLE OF OPERATION OF TRACTION CONTROL The Traction Control prevents drive force loss during slipping of the drive wheels
by automatically applying the brakes and sending engine torque reduction signal to
the PCM when the drive wheels slip or when driving on partly low-friction
surfaces. FAIL-SAFE AND DIAGNOSTIC FUNCTIONS The TCL/ASC-ECU regularly monitors input and out put signals. If an error is
detected in the system, the ECU sends a fail signal and the TCL/ASC indicator light
is illuminated or blinks. Various controls are processed depending on the cause of
malfunction as shown below. When the ABS system fails, the TCL/ASC system is
also suspended. However, when the TCL/ASC system fails, no other systems are
suspended. The appropriate indicator lights are illuminated/flashed.
The TCL/ASC-ECU includes the following functions to make system inspection
easier.
Diagnostic trouble code Display Data list Actuator test
All of the above operations can be carried out using scan tool MB991958.
ACTIVE SKID CONTROL SYSTEM OPERATION The TCL/ASC-ECU receives information from the PCM, the steering sensor, the G
and yaw-rate sensor and the wheel speed sensor. If the ECU determines that the
vehicle is tending to oversteer or understeer, it sends signals to the active skid
control system valves and the ABS solenoid valves to increase the fluid pressure to
the wheels.
The system closes the cut valve to shut the fluid channel to the suction valve, and
activates the

TRACTION CONTROL SYSTEM OPERATION The TCL/ASC-ECU receives information from the PCM, the G and yaw-rate
sensor, and the wheel speed sensor. If the ECU determines that a road wheel is
spinning, it will control the fluid pressure to the spinning wheel to apply torque to
the other road wheels. The operations of the ABS solenoid valves and the active
skid control system valves are the same as for the active skid control system.
Furthermore, the system also controls the engine if the accelerator pedal is
depressed excessively. TCL/ASC DIAGNOSIS INTRODUCTION TO TRACTION CONTROL/ACTIVE SKID CONTROL SYSTEM DIAGNOSIS The traction control/active skid control system (TCL/ASC) is a system that has
added the cut valve and suction valve to the conventional ABS system. These
valves are used to control each of the road wheels independently. These differences
include sounds, sensations, and vehicle performance that owners and service
technicians who are not familiar with TCL/ASC may not be used to.
Some operational characteristics may seem to be malfunctions, but they are simply
signs of normal TCL/ASC operation. When diagnosing the TCL/ASC system, keep
these operational characteristics in mind. Inform the owner of the kind of
performance characteristics to expect from an TCL/ASC-equipped vehicle. TCL/ASC Diagnostic Trouble Code Detection Conditions TCL/ASC diagnostic trouble codes (TCL/ASC DTCs) are set under different
conditions, depending on the malfunction detected. Most TCL/ASC DTCs will only
be set during vehicle operation. Some TCL/ASC DTCs will also be set during the
TCL/ASC self-check immediatel
y after the en
gine is started.
NOTE: *: When the ASC is operating while the brake pedal is
depressed, the suction valve turns on and off according to
the brake fluid amount supplied to the buffer chamber.

1. Jack up the vehicle. Then support the vehicle with rigid racks at the specified
jack-up points or place the front or rear wheels on the rollers of the braking
force tester.
2. Release the parking brake, and feel the drag force (drag torque) on each road
wheel. When using the braking force tester, take a reading of the brake drag
force.
3. Connect scan tool MB991958 to the data link connec
tor. CAUTION:
The roller of the braking force tester and the tire
should be dry during testing. When testing the front brakes, apply the parking
brake. When testing the rear brakes, stop the
front wheels with chocks.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
