GENERAL PROCEDURES
Runout Check —
Brake Disc and Hub
CAUTION: The brake disc (1126) runout specification must be met to ensure correct brake
performance without roughness complaints.
CAUTION: Do not install brake discs that are less than the minimum thickness specified.
Do not machine a brake disc below the minimum thickness specification.
NOTE: When installing brake discs, always align the painted match marks on the brake discs with
those on the front hub or rear axle.
NOTE: When installing brake discs, always apply anti- seize lubricant to the brake disc-to-front hub or
to the brake disc- to-rear axle mating surfaces.
1. Do not remove the tire and wheel assembly. Tighten the wheel nuts to specification with a torque stick or torque wrench.
2. Raise and support the vehicle.
3. Assemble the Brake Measurement Kit, using the spherical tip extension.
4. Locate an opening on the inboard side of the dust shield that will allow the dial indicator tip to be positioned at least 5 mm (0.2 inch) from the outer edge of the brake disc.
5. NOTE: Do not clamp the gauge set to a vehicle component separated from the brake disc by a
flexible joint, such as a ball joint or body mount.
Clamp the Brake Measurement Kit on the vehicle, making sure the flexible indicator arm and
probe tip do not touch the dust shield or tire while rotating.
6. NOTE: For rear wheel measurement only, have an assistant push in on the wheel cover or axle
shaft center while rotating the wheel.
Rotate the wheel for six revolutions, and record the total indicated runout.

DIAGNOSIS AND TESTING
Anti-
Lock Control — Traction Control
Refer to Wiring Diagrams Cell 42 , Anti-
Lock Brake System for schematic and connector information.
Principles of Operation
The anti- lock-brake control module receives wheel speed readings from each anti- lock brake sensor
and processes this information to determine if an ABS event is necessary. The anti- lock brake sensor
electrically senses each tooth of the anti- lock brake sensor indicators as it passes through the anti- lock
brake sensor's magnetic field.
The anti- lock brake control module continuously monitors and compares the rotational speed of each
wheel and, when it detects an impending wheel lock, modulates brake pressure to the appropriate
brake caliper. This is accomplished by triggering the hydraulic control unit (HCU) to open and close the
appropriate solenoid valves. Once the affected wheel returns to normal speed, the anti- lock brake
control module returns the solenoid valves to their normal position, and normal (base) braking
resumes.
The anti- lock brake control module is self- monitoring. When the ignition switch is turned to the RUN
position, the anti- lock brake control module will do a preliminary electrical check, and at approximately
12 km/h (8 mph) the pump motor is turned on for approximately one half- second. Also during all
phases of operation the anti- lock brake control module (after the vehicle is in motion) checks for
correct operation of the anti- lock brake sensors. Any malfunction of the ABS will cause the ABS to shut
off and ABS warning indicator to illuminate; normal power assisted braking, however, remains.
The ABS control module has the ability to store multiple DTCs in memory.
The traction control system controls wheelspin by modulating the engine torque by communicating to
the powertrain control module (PCM) and by applying, then releasing, the appropriate brake to restore
traction when one or both drive wheels lose traction and begin to spin during acceleration.
The traction control system can be disabled by depressing the traction control switch. The traction
control system will reset and return to normal traction assist when the ignition switch is cycled or when
the traction control switch is depressed again. SECTION 206-
