GENERAL INFORMATION
The information in this manual is designed to help
the technician understand and repair the transaxle
with the aid of the built in on-board diagnostics. Chrysler Corporation has developed a com-
plete set of diagnostic manuals which cover the
diagnosis of the 41TE transaxle. They have been
designed to make transaxle diagnosis accurate
and simple. Use these manuals with the DRB II
scan tool and the latest cartridge, when diagnos-
ing transaxle problems.
ON-BOARD DIAGNOSTICS INFORMATION
The 41TE transaxle is controlled and monitored by
the transmission control module. The transmission
control module monitors critical input and output
circuits within the transaxle. Some circuits are tested continuously; others are
checked only under certain conditions. Each circuit
monitored by the transmission control module has a
corresponding fault message assigned to it that can be
read with the DRB II scan tool. If the on-board diagnostic system senses that one of
the circuits is malfunctioning, the corresponding code
is stored in memory. If the malfunction goes away after
the code is stored, the transmission control module will
erase the code after 75 key cycles.
CCD BUS
In order to diagnose the 41TE transaxle, diagnostic
trouble codes in the transmission control module's
memory should be read. Use the Diagnostic Readout
Box (DRB II) scan tool to read codes. If more than one
diagnostic trouble code exists, diagnostic priority
should be given to the most recent code. With CCD bus
bias and communication problems, the DRB II scan
tool displays an appropriate message. Diagnostic
trouble codes might not be accessible until the bus
problem is fixed. The following is a list of probable
causes for a bus problem:
² Open or short to ground/battery in either or both
CCD bus wires (pins 4 and 43).
² Open or short to ground/battery in either or both
41TE transaxle's bias wires (pin 5 and 44) on vehicles
requiring the transaxle to bias the bus.
² Open or short to ground/battery in the diagnostic
connector bus wire. ²
Internal failure of any module connected to the bus.
The CCD bus should have 2.5 volts (+2.5 volts on
CCD+ and -2.5 volts on CCD-). The bus error message displayed by the DRB II scan
tool should be helpful in diagnosing the CCD bus. For more information on diagnosing CCD bus prob-
lems, refer to the 1993 Diagnostic Procedures Manual
(non-communication with the CCD bus). All other
problems refer to the 1993 Body Vehicle Communica-
tions Diagnostic Procedures Manual.
DIAGNOSTIC TROUBLE CODES
Diagnostic Trouble Codes are two-digit numbers that
identify which circuit is malfunctioning. A code can be
set for hydraulic and mechanical reasons as well as for
electrical problems. In most cases, codes do not pin-
point which specific component is defective. Diagnostic trouble codes can only be read with
the use of the DRB II scan tool or equivalent.
HARD FAULTS
Any Diagnostic trouble code that comes back within
3 engine starts (reset count 3 or less) is a ``Hard Fault''.
This means that the defect is there every time the
transmission control module checks that circuit.
SOFT FAULTS
A ``Soft Fault'' is one that occurs intermittently. It is
not there every time the transmission control module
checks the circuit. Most soft faults are caused by wiring
or connector problems. Intermittent defects must be
looked for under the specific conditions that caused
them.
LIMP-IN MODE
The transmission control module continuously
checks for electrical and internal transaxle problems.
When a problem is sensed, the transmission control
module stores a diagnostic trouble code. All but twelve
of these codes cause the transaxle to go into the
``Limp-in mode''. While in this mode, electrical power is
taken away from the transaxle. When this happens,
the only transaxle ranges that will function are:
