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:

line: 548
err: 0xi
User-Requested COLD Boot
Press MORE to switch between this display
and the application screen.
Press F4 when done noting information.
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
Low temperatures will affect the visibility of the
display. Adjust the contrast to compensate for this
condition.
4.0 DISCLAIMERS, SAFETY,
WARNINGS
4.1 DISCLAIMERS
All information, illustrations, and specifications
contained in this manual are based on the latest
information available at the time of publication.
The right is reserved to make changes at any time
without notice.
4.2 SAFETY
4.2.1 TECHNICIAN SAFETY INFORMATION
WARNING: ENGINES PRODUCE CARBON
MONOXIDE THAT IS ODORLESS, CAUSES
SLOWER REACTION TIME, AND CAN LEAD
TO SERIOUS INJURY. WHEN THE ENGINE IS
OPERATING, KEEP SERVICE AREAS WELL
VENTILATED OR ATTACH THE VEHICLE
EXHAUST SYSTEM TO THE SHOP EXHAUST
REMOVAL SYSTEM.
Set the parking brake and block the wheel before
testing or repairing the vehicle. It is especially
important to block the wheels on front-wheel drive
vehicles; the parking brake does not hold drive
wheels.
When servicing a vehicle, always wear eye pro-
tection, and remove any metal jewelry such as
rings, watchbands or bracelets that might make an
inadvertent electrical contact.

When diagnosing a chassis system problem, it is
important to follow approved procedures where
applicable. These procedures can be found in this
General Information Section or in the service man-
ual procedures. Following these procedures is very
important to safety of individuals performing diag-
nostic tests.
4.2.2 VEHICLE PREPARATION FOR
TESTING
Make sure the vehicle being tested has a fully
charged battery. If it does not, false diagnostic codes
or error messages may occur.
4.2.3 SERVICING SUB-ASSEMBLIES
Some components of the chassis system are in-
tended to be serviced as an assembly only. Attempt-
ing to remove or repair certain system sub-
components may result in personal injury and/or
improper system operation. Only those components
with approved repair and installation procedures in
the service manual should be serviced.
4.2.4 DRBIIITSAFETY INFORMATION
WARNING: EXCEEDING THE LIMITS OF THE
DRBIIITMULTIMETER IS DANGEROUS. IT
CAN EXPOSE YOU TO SERIOUS OR
POSSIBLY FATAL INJURY. CAREFULLY
READ AND UNDERSTAND THE CAUTIONS
AND THE SPECIFICATION LIMITS.
²Follow the vehicle manufacturer 's service speci-
fications at all times.
²Do not use the DRBIIItif it has been damaged.
²Do not use the test leads if the insulation is
damaged or if metal is exposed.
²To avoid electrical shock, do not touch the test
leads, tips, or the circuit being tested.
²Choose the proper range and functions for the
measurement. Do not try voltage or current mea-
surement that may exceed the rated capacity.
²Do not exceed the limits shown in the table below:
FUNCTION INPUT LIMIT
Volts 0 - 500 peak volts AC
0 - 500 volts DC
Ohms (resistance)* 0 -1.12 megohms
Frequency Measured
Frequency Generated0-10kHz
Temperature -58 - 1100ÉF
-50 - 600ÉC* Ohms cannot be measured if voltage is present.
Ohms can be measured only in a non-powered
circuit.
²Voltage between any terminal and ground must
not exceed 500v DC or 500v peak AC.
²Use caution when measuring voltage above 25v
DC or 25v AC.
²Use the low current shunt to measure circuits up
to 10A. Use the high current clamp to measure
circuits exceeding 10A.
²When testing for the presence of voltage or cur-
rent, make sure the meter is functioning cor-
rectly. Take a reading of a known voltage or
current before accepting a zero reading.
²When measuring current, connect the meter in
series with the load.
²Disconnect the live test lead before disconnecting
the common test lead.
²When using the meter function, keep the
DRBIIItaway from spark plug or coil wires to
avoid measuring error from outside interference.
4.3 WARNINGS
4.3.1 VEHICLE DAMAGE WARNINGS
Before disconnecting any control module, make
sure the ignition is ªoffº. Failure to do so could
damage the module.
When testing voltage or continuity at any control
module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the
insulation; this will damage it and eventually cause
it to fail because of corrosion. Be careful when
performing electrical tests so as to prevent acciden-
tal shorting of terminals. Such mistakes can dam-
age fuses or components. Also, a second code could
be set, making diagnosis of the original problem
more difficult.
4.3.2 ROAD TESTING A COMPLAINT
VEHICLE
Some complaints will require a test drive as part
of the repair verification procedure. The purpose of
the test drive is to try to duplicate the diagnostic
code or symptom condition.

CHRYSLER VOYAGER 2001 Service Manual Symptom List:
FCM, ORC RUN ONLY DRIVER OPEN - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER CURRENT - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER TEMP - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER VOLT - ACTIVE
FCM, ORC RUN

Symptom List:
FCM, ORC RUN ONLY DRIVER OPEN - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER CURRENT - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER TEMP - ACTIVE
FCM, ORC RUN ONLY DRIVER OVER VOLT - ACTIVE
FCM, ORC RUN ONLY DRIVER SHORT TO GROUND - ACTIVE
ORC, LOSS OF IGNITION RUN ONLY - ACTIVE
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be FCM, ORC RUN ONLY DRIVER
OPEN - ACTIVE.
When Monitored and Set Condition:
FCM, ORC RUN ONLY DRIVER OPEN - ACTIVE
When Monitored: When the ignition is turned OFF, the microprocessor controlled
transistor (high side driver) places a diagnostic voltage on the ORC Run-Start circuit for
60 seconds. An open high side driver (HSD) circuit voltage is between 2.4 and 5.0 volts.
Set Condition: This code will set within 10 second, if the microprocessor senses 2.4 to 5.0
volts on the HSD. Note: the diagnostic voltage will only last for 60 seconds after the
ignition is turned off.
FCM, ORC RUN ONLY DRIVER OVER CURRENT - ACTIVE
When Monitored: The FCM uses a microprocessor controlled transistor (high side driver)
to supply power to the ORC. The microprocessor monitors the high side driver (HSD)
internal temperature when the ignition is in the Run Only position.
Set Condition: The code will set within 1 second, if the microprocessor senses HSD
internal temperature. The high temperature is caused by over current.
FCM, ORC RUN ONLY DRIVER OVER TEMP - ACTIVE
When Monitored: The FCM uses a microprocessor controlled transistor (high side driver)
to supply power to the ORC. The microprocessor monitors the high side driver (HSD)
internal temperature when the ignition is in the Run position.
Set Condition: The code will set within 2.5 second, if the microprocessor senses high HSD
internal temperature. The high temperature is caused by over current.
FCM, ORC RUN ONLY DRIVER OVER VOLT - ACTIVE
When Monitored: The FCM uses a microprocessor controlled transistor (high side driver)
to supply power to the ORC. The microprocessor monitors the high side driver (HSD)
battery voltage when the ignition is in the run position.
Set Condition: The code will set if the microprocessor senses HSD battery voltage is over
30 volts.
