If the DRBIIIt should display any other error
message, record the entire display and call the
S.T.A.R. Center.
3.5.1 DRBIIIT DOES NOT POWER UP
(BLANK SCREEN)
If the LED’sdo not light or no sound isemitted at
start up, check for loose cable connections or a bad
cable. Check the vehicle battery voltage. A mini-
mum of 11 volts is required to adequately power
the DRBIIIt.
If all connections are proper between the
DRBIIIt and the vehicle or other devices, and the
vehicle battery is fully charged, an inoperative
DRBIIIt may be the result of faulty cable or vehicle
wiring. For a blank screen, refer to the appropriate
Body Diagnostic manual.
3.5.2 DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the
display. Adjust the contrast to compensate for this
condition.
3.5.3 SOME DISPLAY ITEMS READ “---”
This is caused by the scrolling the DRBIIIt
display a single line up or down. The line which
was scrolled onto the screen might read “---”. Use
the page down or page up function to display the
information.
3.6 TRANSMISSION SIMULATOR (MILLER
TOOL #8333) AND ELECTRONIC
TRANSMISSION ADAPTER KIT
(MILLER TOOL #8333-1A)
NOTE: Remove the starter Relay when using
the transmission simulator
• Failure to remove the Starter Relay can
cause a PCM - No Response condition.
• The removal of the Starter Relay will also
prevent the engine from starting in gear.
• The Transmission Simulator will not
accurately diagnose intermittent faults.
The transmission simulator, simply put, is an
electronic device that simulates the electronic func-
tions of any EATX or NGC controlled transmission.
The transmission Simulators basic function is to
aid the technician in determining if an internal
transmission problem exists or if the problem re-
sides in the vehicle wiring or control module. It is
only useful for electrical problems. It will not aid in
the diagnosis of a failed mechanical component,
but it can tell you that the control module and
wiring are working properly and that the problem
is internal.
The ignition switch should be in the lock position
before attempting to install the simulator. Follow
all instructions included with the simulator. If the
feedback from the simulator is in doubt, you can
verify it’s operation by installing it on a known
good vehicle. A “known good vehicle” would be
defined as a vehicle that does not set any DTC’s
and drives and shifts as expected.
One important point to remember is that the
Simulator receives it’s power from the Trans Relay
Output circuit. If the transmission system is in
Limp−in (Relay open), the simulator will not oper-
ate. This is not really an indication of a problem,
but an additional symptom. If the simulator does
not power up (‘‘P’’ led lit), this is an indication that
the problem is still present with the simulator
hooked up. This indicates that the problem is in the
wiring or control module and not the transmission.
Miller Tool # 8333-1A consists of the adapter
cables and overlay necessary to adapt the 8333
simulator to TE/AE/LE/RLE transmissions.

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 wheels
before testing or repairing the vehicle. It is espe-
cially important to block the wheels on front-wheel
drive vehicles: the parking brake does not hold the
drive wheels.
Some operations in this manual require that
hydraulic tubes, hoses, and fittings, disconnected
