these inputs to the CAB should be investigated if a
complaint of intermittent warning system operation
is encountered.
(12) Low system voltage. If Low System Voltage is
detected by the CAB, the CAB will turn on the ABS
Warning Lamp until normal system voltage is
achieved. Once normal voltage is seen at the CAB,
normal operation resumes.
(13) High system voltage. If high system voltage is
detected by the CAB, the CAB will turn on the
Amber ABS Warning Lamp until normal system volt-
age is achieved. Once normal voltage is again
detected by the CAB, normal ABS operation will be
resumed at the next key on cycle.
(14) Additionally, any condition which results in
interruption of electrical current to the CAB or mod-
ulator assembly may cause the ABS Warning Lamp
to turn on intermittently.
(15) The body controller can turn on the (yellow)
ABS warning lamp if CCD communication between
the body controller and the CAB is interupted.
TONEWHEEL INSPECTION
CAUTION: The tone wheels used on this vehicle
equipped with the Teves Mark 20 Antilock Brake
System are different then those used on past mod-
els of this vehicle equipped with antilock brakes.
Reduced braking performance will result if this part
is used on earlier model vehicles and an accident
could result. Do not use on pre-1998 model year
vehicles.
Carefully inspect tonewheel at the suspected faulty
wheel speed sensor for missing, chipped or broken
teeth, this can cause erratic speed sensor signals.
Tonewheels should show no evidence of contact
with the wheel speed sensors. If contact was made,
determine cause and correct before replacing the
wheel speed sensor.
Excessive runout of the tonewheel can cause
erratic wheel speed sensor signals. Refer to Tone-
wheel Runout in the Specification Section in this sec-
tion of the service manual for the tonewheel runout
specification. Replace drive shaft assembly or rear
hub/bearing assembly if tonewheel runout exceeds
the specification.
Inspect tonewheels for looseness on their mounting
surfaces. Tonewheels are pressed onto their mounting
surfaces and should not rotate independently from
the mounting surface.
Check the wheel speed sensor head alignment to
the tone wheel. Also check the gap between the speed
sensor head and the tone wheel to ensure it is at
specification. Refer to Wheel Speed Sensor Clearance
in the Specification Section in this section of the ser-
vice manual.
PROPORTIONING VALVE
CAUTION: Proportioning valves (Fig. 18) should
never be disassembled.
If premature rear wheel skid occurs on hard brake
application, it could be an indication that a malfunc-
tion has occurred with one of the proportioning
valves.
If a malfunctioning proportioning valve is sus-
pected on a vehicle, refer to Proportioning Valve Test
in the Proportioning Valves Section in this group of
the service manual for the required test procedure.
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or
deteriorated rubber parts.
Swollen rubber parts indicate the presence of
petroleum in the brake fluid.
To test for contamination, put a small amount of
drained brake fluid in clear glass jar. If fluid sepa-
rates into layers, there is mineral oil or other fluid
contamination of the brake fluid.
If brake fluid is contaminated, drain and thor-
oughly flush system. Replace master cylinder, propor-
tioning valve, caliper seals, wheel cylinder seals,
Antilock Brakes hydraulic unit and all hydraulic
fluid hoses.
TEST DRIVING ABS COMPLAINT VEHICLE
Most ABS complaints will require a test drive as a
part of the diagnostic procedure. The purpose of the
test drive is to duplicate the condition.
NOTE: Remember conditions that result in the
turning on of the Red BRAKE Warning Lamp may
indicate reduced braking ability. The following pro-
cedure should be used to test drive an ABS com-
plaint vehicle.

DIAGNOSIS AND TESTING (Continued)
Before test driving a brake complaint vehicle, note
whether the Red or Amber Brake Warning Lamp is
turned on. If it is the Red Brake Warning Lamp,
refer to the hydraulic system section in the brake
group of this manual. If the ABS Warning lamp
was/is on, test drive the vehicle as described below, to
verify the complaint. While the ABS Warning Lamp
is on, the ABS is not functional. The standard brake
system and the ability to stop the car may not be
affected if only the ABS Warning Lamp is on.
Discuss with the owner of the vehicle or note any
other electrical problems or conditions that may be
occurring on the vehicle. They may have an effect on
the antilock brake system's function.
(1) Turn the key to the off position and then back
to the on position. Note whether the ABS Warning
Lamp continues to stay on. If it does, refer to the
diagnostic manual covering the ITT Teves Mark 20
ABS system for the required test procedures.
(2) If the ABS Warning Lamp goes out, shift into
gear and drive the car to a speed of 20 kph (12 mph)
to complete the ABS start up cycle. If at this time the
ABS Warning Lamp goes on refer to the ITT Teves
Mark 20 Diagnostic Manual.
(3) If the ABS Warning Lamp remains OUT, drive
the vehicle a short distance. During this test drive be
sure that the vehicle achieves at least 40 mph. Brake
to at least one complete stop in an ABS cycle, and
again accelerate to 25 mph.
(4) If a functional problem with the ABS system is
determined while test driving a vehicle, refer to the
diagnostic manual covering the ITT Teves Mark 20
ABS system for the required test procedures and
proper use of the DRB diagnostic scan tool.
ABS SERVICE PRECAUTIONS
The ABS uses an electronic control module, the
CAB. This module is designed to withstand normal
current draws associated with vehicle operation.
Care must be taken to avoid overloading the CAB
circuits.In testing for open or short circuits, do
not ground or apply voltage to any of the cir-
cuits unless instructed to do so for a diagnostic
procedure.These circuits should only be tested
using a high impedance multi-meter or the DRB
tester as described in this section. Power should
never be removed or applied to any control module
with the ignition in the ON position. Before removing
or connecting battery cables, fuses, or connectors,
always turn the ignition to the OFF position.
CAUTION: Use only factory wiring harnesses. Do
not cut or splice wiring to the brake circuits. The
addition of after-market electrical equipment (car
phone, radar detector, citizen band radio, trailer
lighting, trailer brakes, ect.) on a vehicle equippedwith antilock brakes may affect the function of the
antilock brake system.
SERVICE PROCEDURES
BRAKE FLUID LEVEL INSPECTION
CAUTION: Use only Mopar brake fluid or an equiv-
alent from a tightly sealed container. Brake fluid
must conform to DOT 3 specifications. Do not use
petroleum-based fluid because seal damage in the
brake system will result.
For the specific procedure covering the inspection
of the brake fluid level and adding brake fluid to the
reservoir, refer to the Service Adjustments Section in
this group of the service manual.
BLEEDING TEVES MARK 20 HYDRAULIC SYSTEM
The base brake system must be bled anytime air is
permitted to enter the hydraulic system, due to dis-
connection of brake lines, hoses or components. The
ABS system, particularly the HCU, should only be
bled when the HCU is replaced or removed from the
vehicle, or if there is reason to believe the HCU has
ingested air. Under most circumstances that would
require brake bleeding, only the base brake system
needs to be bled.
It is important to note that excessive air in the
brake system will cause a soft or spongy feeling
brake pedal.
During bleeding operations, be sure that the brake
fluid level remains close to the FULL level in the res-
ervoir. Check the fluid level periodically during the
bleeding procedure and add DOT 3 brake fluid as
required.
The Teves Mark 20 ABS hydraulic system and the
base brake hydraulic system must be bled as two
independent braking systems. The non ABS portion
of the brake system is to be bled the same as any
non ABS system. Refer to the Service Adjustments
section in this manual for the proper bleeding proce-
dure to be used. This brake system can be either
pressure bled or manually bled.
The ABS portion of the brake system MUST be
bled separately. This bleeding procedure requires the
use of the DRB Diagnostic Tester and the bleeding
sequence procedure outlined below.
ABS BLEEDING PROCEDURE
When bleeding the ABS system, the following
bleeding sequenceMUSTbe followed to insure com-
plete and adequate bleeding. The ABS system can be
bled using a manual bleeding procedure or standard
pressure bleeding equipment.
NSBRAKES 5 - 99
DIAGNOSIS AND TESTING (Continued)
If the brake system is to be bled using pressurized
bleeding equipment, refer to Bleeding Brake System
in the Service Adjustments section at the beginning
of this group for proper equipment usage and proce-
dures.
(1) Assemble and install all brake system compo-
nents on the vehicle making sure all hydraulic fluid
lines are installed and properly torqued.
(2) Connect the DRB Diagnostics Tester to the
diagnostics connector. The Teves Mark 20 ABS diag-
nostic connector is located under the instrument
panel to the left of the steering column cover.
(3) Using the DRB, check to make sure the CAB
does not have any fault codes stored. If it does,
remove them using the DRB.
WARNING: WHEN BLEEDING THE BRAKE SYS-
TEM WEAR SAFETY GLASSES. A CLEAR BLEED
TUBE MUST BE ATTACHED TO THE BLEEDER
SCREWS AND SUBMERGED IN A CLEAR CON-
TAINER FILLED PART WAY WITH CLEAN BRAKE
FLUID. DIRECT THE FLOW OF BRAKE FLUID AWAY
FROM THE PAINTED SURFACES OF THE VEHICLE.
BRAKE FLUID AT HIGH PRESSURE MAY COME
OUT OF THE BLEEDER SCREWS WHEN OPENED.
(4) Bleed the base brake system using the stan-
dard pressure or manual bleeding procedure as out-
lined in the Service Adjustments section of this
service manual.
(5) Using the DRB, go to the9Bleed ABS9routine.
Apply the brake pedal firmly and initiate the9Bleed
ABS9cycle one time. Release the brake pedal.
(6) Bleed the base brake system again, as in step
Step 4 above.
(7) Repeat steps Step 5 and Step 6 above until
brake fluid flows clear and is free of any air bubbles.
Check brake fluid level in reservoir periodically to
prevent reservoir from running low on brake fluid.
(8) Test drive the vehicle to be sure brakes are
operating correctly and that brake pedal is solid.
REMOVAL AND INSTALLATION
ABS GENERAL SERVICE PRECAUTIONS
CAUTION: Review this entire section prior to per-
forming any mechanical work on a vehicle equipped
with the ITT Tevis Mark 20 ABS brake system. This
section contains information on precautions per-
taining to potential component damage, vehicle
damage and personal injury which could result
when servicing an ABS equipped vehicle.
CAUTION: Only the recommended jacking or hoist-
ing positions for this vehicle are to be used when-ever it is necessary to lift a vehicle. Failure to raise
a vehicle from the recommended locations could
result in lifting a vehicle by the hydraulic control
unit mounting bracket. Lifting a vehicle by the
hydraulic control unit mounting bracket will result
in damage to the mounting bracket and the hydrau-
lic control unit.
CAUTION: Certain components of the ABS System
are not intended to be serviced individually.
Attempting to remove or disconnect certain system
components may result in improper system opera-
tion. Only those components with approved
removal and installation procedures in this manual
should be serviced.
CAUTION: Brake fluid will damage painted sur-
faces. If brake fluid is spilled on any painted sur-
faces, wash off with water immediately.
CAUTION: When performing any service procedure
on a vehicle equipped with ABS do not apply a 12
volt power source to the ground circuit of the pump
motor in the CAB. Doing this will damage the pump
motor and will require replacement of the HCU.
The following are general cautions which should be
observed when servicing the ABS system and/or
other vehicle systems. Failure to observe these pre-
cautions may result in ABS System component dam-
age.
If welding work is to be performed on the vehicle,
using an electric arc welder, the CAB connector
should be disconnected during the welding operation.
The CAB 25 way connector connector should never
be connected or disconnected with the ignition switch
in the ON position.
Many components of the ABS System are not ser-
viceable and must be replaced as an assembly. Do not
disassemble any component which is not designed to
be serviced.
