2001 CHRYSLER VOYAGER parking brake

defined as the amount of time from the start of a
wipe to the beginning of the next wipe. The rear
wiper system delay time is based on the following:
7.75 - (MPH x .05) = Seconds delay
Examples:
At zero (0) MPH the delay is 7.75 seconds.
At 100 MPH the delay is 2.75 seconds.
3.21.8 WIPE AFTER WASH
When the driver presses the wash button for over
1.5 seconds and releases it, the wiper will continue
to run for 2 additional wipe cycles.
3.22 USING THE DRBIIIT
Refer to the DRBIIItuser guide for instructions
and assistance with reading trouble codes, erasing
trouble codes, and other DRBIIItfunctions.
3.22.1 DRBIIITERROR MESSAGES
Under normal operation, the DRBIIItwill dis-
play one of only two error messages: user-requested
WARM Boot or User-Requested COLD Boot. If the
DRBIIItshould display any other error message,
record the entire display and call the STAR Center.
This is a sample of such an error message display:

3.22.2 DRBIIITDOES NOT POWER UP
(BLANK SCREEN)
If the LED's do not light or no sound is emitted at
start up, check for loose cable connections or a bad
cable. Check the vehicle battery voltage (data link
connector cavity 16). A minimum of 11 volts is
required to adequately power the DRBIIIt. Check
for proper grounds at DLC cavities 4 and 5.
If all connections are proper between the
DRBIIItand the vehicle or other devices, and the
vehicle battery is fully charged, an inoperative
DRBIIItmay be the result or a faulty cable or
vehicle wiring.
3.22.3 DISPLAY IS NOT VISIBLE

GENERAL INFORMATION

The cycling of the build and decay valves is
similar to the ABS except that they work to control
wheel spin by applying brakes. ABS function is to
control wheel skid by releasing brakes.
Two pressure relief valves allow excess fluid vol-
ume to return to the reservoir when not used by the
build/decay cycles. These are required because the
pump supplies more volume than the traction con-
trol system requires.
If at any time the brake pedal is applied during a
traction control cycle, the brake lamp switch will
trigger the CAB to switch off the traction control.
The traction control system will be enabled at
each ignition cycle. It may be turned off by depress-
ing the Traction Control Switch. The traction con-
trol system function lamp will illuminate ªTRAC
OFFº immediately upon depressing the traction
control switch button. Only the ªTRACº portion of
the ªTRAC OFFº indicator will illuminate during a
traction control event. If the CAB calculates that
the brake temperatures are high, the traction con-
trol system will become inoperative until a time-out
period has elapsed. When in this thermal protection
mode, the traction control ªTRAC OFFº lamp will
illuminate; however, a fault will not be registered.
3.3 SYSTEM COMPONENTS
²controller antilock brake (CAB)
²vacuum booster
²master cylinder
²ABS integrated electronic control module/
hydraulic control unit (HCU), valve block assem-
bly: 8 valve solenoids (4 inlet valves, 4 outlet
valves, 2 accumulators) 1 motor, 2 pump
²ABS integrated electronic control module with
traction control same as above but has 10 valve
solenoids.
²4 wheel speed sensor/tone wheel assemblies
²ABS warning indicator
²fuses and wiring harness
²fluid reservoir
²TRAC/TRAC OFF indicator
3.3.1 ABS AND BRAKE WARNING
INDICATORS
The amber ABS warning indicator is located in
the instrument cluster. It is used to inform the
driver that the antilock function has been turned
off. The ABS warning indicator is controlled by the
CAB. The CAB controls the lamp with a command
over the PCI bus.
The ABS Warning Indicator will remain lit during
every key cycle until a circuit or component fault is
repaired and the CAB no longer detects the fault.After repair of a sensor signal fault or a pump motor
fault, the CAB must sense all four wheels at 25
km/h (15 mph) before it will extinguish the ABS and
TRAC OFF Indicators.
The Instrument Cluster will illuminate the ABS
Warning Indicator if it loses communication with
the CAB.
The red BRAKE warning indicator is also located
in the instrument cluster. It can be activated in
several ways. Application of the parking brake or a
low fluid signal from the fluid level switch located in
the master cylinder reservoir will cause the indica-
tor to come on.
3.3.2 CONTROLLER ANTILOCK BRAKE
(CAB)
The Controller Antilock Brake (CAB) is a
microprocessor-based device that monitors wheel
speeds and controls the antilock functions. The
CAB contains two microprocessors that receive
identical sensor signals and then independently
process the information. The results are then com-
pared to make sure that they agree. Otherwise, the
CAB will turn off the antilock and turn on the ABS
amber warning indicator.
The primary functions of the CAB are to:
²detect wheel locking tendencies
²control fluid pressure modulation to the brakes
during antilock stop
²monitor the system for proper operation
²manage traction control functions
²provide communication to the DRBIIItwhile in
diagnostic mode
²store diagnostic information in non-volatile memory
The CAB continuously monitors the speed of each
wheel. When a wheel locking tendency is detected,
the CAB will command the appropriate valve to
modulate brake fluid pressure in its hydraulic unit.
Brake pedal position is maintained during an an-
tilock stop by being a closed system with the use of
2 accumulators. The CAB continues to control pres-
sure in individual hydraulic circuits until a wheel
locking tendency is no longer present. The CAB
turns on the pump motor during an antilock stop.
The antilock brake system is constantly moni-
tored by the CAB for proper operation. If the CAB
detects a system malfunction, it can disable the
antilock system and turn on the ABS warning
indicator. If the antilock function is disabled, the
system will revert to standard base brake system
operation.
The CAB inputs include the following:
²diagnostic communication
²four wheel speed sensors

FASTENER IDENTIFICATION
DESCRIPTION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 10.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts.

HOISTING
STANDARD PROCEDURE - HOISTING
Refer to Owner's Manual provided with vehicle for
proper emergency jacking procedures.
WARNING: THE HOISTING AND JACK LIFTING
POINTS PROVIDED ARE FOR A COMPLETE VEHI-
CLE. WHEN THE ENGINE OR REAR SUSPENSION
IS REMOVED FROM A VEHICLE, THE CENTER OF
GRAVITY IS ALTERED MAKING SOME HOISTING
CONDITIONS UNSTABLE. PROPERLY SUPPORT OR
SECURE VEHICLE TO HOISTING DEVICE WHEN
THESE CONDITIONS EXIST.
CAUTION: Do not position hoisting device on any
suspension component, including the front suspen-
sion crossmember, the rear leaf springs, and the
rear axle. Do not hoist on the front and rear
bumpers, the lower liftgate crossmember, the lower
radiator crossmember, the down standing flanges
on the sill or the front engine mount.
FOR PROPER HOIST PLACEMENT REFER
TO (Fig. 8).
The hoisting points are identified by S.A.E.
inverted triangle hoisting symbols (Fig. 8). The front
hoisting points are at the bottom of the font rail
below the hoisting symbol approximately 250mm
behind the front suspension crossmember. When
using outboard lift hoists, verify that the hoist lift
pads have been properly adjusted to eliminate con-
tact between the hoist arm and the down standing
flange on the sill. The rear hoisting points are the
leaf spring front mounting brackets. The hoist pad
must be positioned to pick up the flanges on the
bracket, not the leaf spring.
When servicing the leaf springs or the leaf spring
mounting brackets, special provisions are required to
support the rear of the vehicle. Position the rear
hoist pads under the horizontal surface on the bot-
tom of the sill, inboard adjacent to the flange and
centered fore/aft between the jacking indicator tabs
on the lower flange.DO NOT HOIST ON THE
FLANGE.Place a soft pad between the hoist and the
painted surface on the sill to avoid scratching the fin-
ish.
JUMP STARTING
TO JUMP START A DISABLED VEHICLE:
(1) Raise hood on disabled vehicle and visually
inspect engine compartment for:
²Battery cable clamp condition, clean if necessary.
²Frozen battery.
²Yellow or bright color test indicator, if equipped.
²Low battery fluid level.
