For vehicles with Automatic Traction Control (ATC), the ATC
function must be disabled (ATC indicator lamp should be ON,
see Dynamometer Test Mode, page 8-63) prior to performing
any vehicle maintenance where one or more wheels on a
drive axle are lifted off the ground and moving.
ATC Valve
Removal
1. Disconnect the wiring electrical connector (4),
(Figure 8-62) from the ATC valve.
2. Disconnect the air lines from the supply (1),
(Figure 8-62) and delivery port (2), (Figure 8-62) and
treadle port (3), (Figure 8-73) of the ATC valve.
3. Disconnect the valve mounting fasteners, and remove
the valve.
Installation
1. Install the ATC valve. Torque fasteners to manufacturers
specification.
2. Connect air lines to the supply port (1), (Figure 8-62)
delivery port (2), (Figure 8-62) and treadle port (3),
(Figure 8-62) of the ATC valve.
3. Install the wiring connector to the ATC valve.
4. Test the installation.
Leak Test: Traction Control Valve
Make and hold brake application. No audible air leaks are
permitted.
Traction Control Valve Component Test with Hand-
Held Diagnostic Tool
1. Select Traction Control Valve.
2. Verify traction control light operation.
3. Drive the vehicle and verify ABS indicator lamp operates
properly.
Modulator Valves M-32, M-32QR
Removal
1. Locate the modulator that will be replaced and clean the
exterior.
2. Identify and mark or label all air lines and their
respective connections on the valve to facilitate ease of
installation.
3. Disconnect all air lines and the electrical connector.
4. Remove all air line fittings and plugs. These fittings will
be re-used in the replacement modulator.
Installation
1. Install all air line fittings and plugs, making certain thread
sealing material does not enter the valve.
2. Install the assembled valve on the vehicle.
3. Reconnect all air lines to the valve using the
identification made during removal.
4. Reconnect the electrical connector to the modulator.
5. After installing the valve, test all air fittings for excessive
leakage and tighten as needed.
Wheel Speed Sensor Replacement (Front)
Removal
Refer to (Figure 8-84).
1. Park the vehicle on a level surface. Apply the parking
brake, place the transmission in neutral and block the
rear wheels. Make sure vehicle ignition is in the “OFF”
position.
2. Raise the wheel where the faulty sensor is located.
Place jack stands of adequate rating under the axle.
3. Remove the wheel from the axle.
4. If equipped with spring brakes, release the brakes. Back
off the slack adjuster.
5. Remove the brake drum, cam rollers, return spring and
brake shoes.
NOTE: DO NOT pull on the sensor cable to remove it, as
this may permanently damage the sensor. DO NOT
use any device to pry the sensor from its mounting
block, as this may damage the steel casing on the
sensor and can void any existing warranty.
6. Remove the mounting bolts for the sensor bracket (2),
(Figure 8-84). Cut the tie straps along the sensor cable.
Remove the P-clips at the S-cam tube, bracket and
frame rail. Using a slight twisting motion, remove the
sensor from its mounting block. Use extreme care not to
damage the tooth wheel or the sensor.
WARNING
Personal Injury and Machine Damage Hazard!
Do not start and engage the transmission with one wheel
raised from the floor. With ATC, power will go to the wheel
on the floor and cause the vehicle to move which can
injure personnel or damage the machine.
See Dynamometer Test Mode, page 8-63 to disable ATC
for dyno testing.
