General Information - Diagnostic Trouble Code (DTC) Index DTC: Transmission
Shift Module (GSM)
Description and Operation

Gear Shift Module (GSM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as needed

The table below lists all diagnostic trouble codes (DTCs) that could be logged in the gear shift module, for additional diagnosis
and testing information refer to the relevant diagnosis and testing section.
For additional information, refer to: External Controls (307-05 Automatic Transmission/Transaxle External Controls - V6 3.0L
Petrol, Diagnosis and Testing).

message error - Alive counter fault
Refer to the electrical circuit diagrams and
check LIN input signal circuit for short circuit
to ground, short circuit to power, open
circuit, high resistance. Check transmission
control module for related DTCs and refer to
relevant DTC index

DTC Description Possible Causes Action B1087-83
LIN Bus "A" - Value
of signal protection
calculation
incorrect
Transmission control module LIN
message error - checksum fault
Refer to the electrical circuit diagrams and
check LIN input signal circuit for short circuit
to ground, short circuit to power, open
circuit, high resistance. Check transmission
control module for related DTCs and refer to
relevant DTC index B1087-87 LIN Bus "A" -
Missing message
Transmission control module LIN
message error - Missing message
Refer to the electrical circuit diagrams and
check LIN input signal circuit for short circuit
to ground, short circuit to power, open
circuit, high resistance. Check transmission
control module for related DTCs and refer to
relevant DTC index B1142-62
Ignition Status 1 -
Signal compare
failure
Hardwired ignition and CAN
powermode signals differ
Refer to the electrical circuit diagrams and
check ignition supply circuit for short circuit
to ground, short circuit to power, open
circuit, high resistance B123C-01
Dynamic Stability
Control Status
Indicator - General
Electrical Failure
Dynamic stability control LED failure
Check transmission shift module, check
operation of the dynamic stability control
button status illumination, check and install
new transmission shift module as required.
Refer to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module B123D-64
Dynamic Stability
Control Button -
Signal plausibility
failure
Dynamic stability control button may
be stuck, may be due to a faulty
button or to the user holding the
button for a prolonged period
(dynamic stability control button
detected as pressed for 30 seconds)
(S1)
Check for normal dynamic stability control
button functionality. If it operates normally
then no further action required. If the
dynamic stability control button fails to
operate normally then may be due to an
internal fault, check and install new
transmission shift module as required. Refer
to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module B123F-01
Adaptive Speed
Limiter Mode
Indicator - General
Electrical Failure
Adaptive speed limiter LED failure
Check transmission shift module, check
operation of the active speed limiter button
status illumination, check and install new
transmission shift module as required. Refer
to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module B1241-64
Adaptive Speed
Limiter Button -
Signal plausibility
failure
May be due to a faulty button or to
the user holding the button for a
prolonged period (adaptive speed
limiter button detected as pressed
for 30 seconds)
Check for normal adaptive speed limiter
button functionality. If it operates normally
then no further action required. If the
adaptive speed limiter button fails to
operate normally then may be due to an
internal fault, check and install new
transmission shift module as required. Refer
to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module B1242-64
Winter Button -
Signal plausibility
failure
May be due to a faulty button or to
the user holding the button for a
prolonged period (winter button
detected as pressed for 30 seconds)
Check for normal winter button functionality.
If it operates normally then no further action
required. If the winter button fails to operate
normally then may be due to an
internal fault, check and install new
transmission shift module as required. Refer
to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module www.JagDocs.com
