3.5.1 DRBIII DOES 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. A mini-
mum of 11 volts is required to adequately power the
DRBIII .
If all connections are proper between the
DRBIII and the vehicle or other devices, and the
vehicle battery is fully charged, an inoperative
DRBIII 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.
GENERAL INFORMATION
3.6 TRANSMISSION SIMULATOR (MILLER
TOOL #8333) AND FWD ADAPTER
(MILLER TOOL #8333-1)
The transmission simulator, simply put, is an
electronic device that simulates the electronic func-
tions of any EATX controlled transmission (41TE,
41TE, and 45RFE). It's basic function is to aid the
technician in determining if an internal transmis-
sion problem exists or if the problem resides in the
vehicle wiring or Transmission Control Module
(TCM). 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 TCM 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 TCM and not the transmission.
Miller Tool #8333-1 consists of the adapter cables
and overlay necessary to adapt the simulator to
41TE and 41TE transmissions.
