TROUBLE CODE DIAGNOSIS - GASOLINE VEHICLE
TCM DIAGNOSTIC SYSTEM
OVERVIEW
Notice: To prevent Transmission Control Module (TCM)
damage. The ignition key must be OFF when
disconnection or reconnection the power to the TCM
(for example bttery cable, TCM pigtail connector, TCM
fuse, jumper cables, etc.).
When the TCM detects a system fault, a Diagnostic
Trouble Code (DTC) is set in the TCM. This code is
present while the fault conditions are met and is stored
as a ‘History DTC’ until cleared. Condition for setting
and clearing each TCM DTC are provided in the relevant
sections.
In the case where the vehicle type is certified for Eure
On-Board Diagnostic (EOBD) compliance, the Engine
Control Module (ECM) provides the communication linkto the EOBD scan tool to pass on any EOBD relevant
codes from the TCM. The table below contains a list of
all supported DTCs and the classification of each for
EOBD purposes. Where a type B DTC has been set in
an EOBD vehicle, the response to the fault may include
action by the ECM, including the illumination of the
Malfunction lndicator Lamp (MIL). Refer to Section 1F,
Engine Control, for details on EOBD system function,
checks and fault clearing.
CLEARING TROUBLE CODES
TCM DTCs should be cleared after repairs have been
completed. Some diagnostic tables will tell you to clear
the codes before using the chart, which will help to
find the cause of the problem more quickly. Always
note the DTCs present before clearing - this information
may be helpful in the diagnostic process.”

DIAGNOSTIC TROUBLE CODES (Cont'd)
DTC Types
Each DTC is directly related to a diagnostic test. The
Diagnostic management system sets DTCs based on
the failure of the tests during a driving cycle or cycles.
The following are the two types of DTCs and the charac-
teristics of those codes;
Type B
Emissions related.
EOBD system “Armed” after one driving cycle with
a fail.
EOBD system “Disarmed” after one driving cycle
with a pass.
Illuminates the MIL on the second con-secutive
driving cycle with a fail.
TCM stores a history DTC on the first driving cycle
with a fail.
EOBD system stores a history DTC on the second
consecutive driving cycle with a fail, (the DTC will
be armed after the first fail).
EOBD system stores a freeze frame on the second
consecutive driving cycle with a fail, (if empty).
Type D
Non-Emissions related.
Does not request illumination of any lamp.
Stores a history DTC on the first driving cycle with
a fail.
EOBD system does not store a freeze frame. DTC

Circuit Description
The Transmission Control Module (TCM) Diagnistic
System Check is the starting point for any driveability
complaint diagnosis. Before using this procedure,
perform a careful visual/physical check of the
Transmission Control Module (TCM) and the
transmission grounds for cleanliness and tightness.
The TCM Diagnostic System Check is an organized
approach to identifying a problem created by an
electronic transmission control system malfunction.
TCM DIAGNOSTIC SYSTEM CHECK
Diagnostic Aids
An intermittent fault may be caused by a poor connec-
tion, rubbed-through wire insulation or a wire broken
inside the insulation. Check for poor connections or a
damaged harness. Inspect the TCM harness and con-
nections for improper mating, broken locks, improperly
formed or damaged terminals, poor terminal-to-wire
connection, and damaged harness.

ground circuit for an open.
Is a problem found?
Repair the open, short to ground or short to voltage in
the serial data circuit or the DLC ignition feed circuit
or the DLC ground circuit.
Is a repair complete?
Check the TCM ignition feed circuit for an open or
short to ground and the TCM ground circuit for an
open.
Is a problem found?
Repair the open or short to ground in the TCM ignition
feed circuit or the TCM ground circuit.
Is a repair complete?
1. Turn the ignition OFF.

5A-54 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmission case. The TR sensor Indicates to the TCM
which gear position has been selected by way of a
varying resistance.
The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever
(PRND321). The Transmission Control Module (TCM)
receives that signal with a voltage varying from 0 V to
5 V. DTC P0706 sets when the TR sensor signal is not
feasi ble.
Conditions for Setting the DTC
•The engine temperature is greater than 60 °C (140 °F).
The engine speed is greater than 2000 RPM and
less than 4000 RPM.
Engine load is greater than 60 %.
DTCs P0707, P0708, P1703 and P1719 are not set.
Transmission temperature is greater than 0 °C (32 °F)
or if P0710 is present the engine coolant
temperature is greater than 60 °C (140 °F).
The TR sensor indicates that the transmission is in
a neutral state, however the engine output torque
indicates that a drive gear load is present. This
condition must be continuously present for 5
seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P0706
TRANSMISSION RANGE SENSOR CIRCUIT RANGE/PERFORMANCE
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.
The EOBD system will record operating conditions
at the time the diagnostic fails. This information will
be stored in the Failure Records buffer.
TR signal is assumed to be in the Drive position.
The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.
Torque Converter Clutch (TCC) is disabled.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc-
curred for 30 seconds and TR is in P, R, N or D.
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
Inspect the wiring for poor electrical connections
at the TCM and at the TR sensor connector. Look
for possible bent, backed out, deformed or damaged
ter-minals. Check for weak terminal tension as well.
Also, check for chafed wires that could short to bare
metal or other wiring. Inspect for broken wires inside
the in-sulation.

Perform a Transmission Control Module (TCM)
Diagnostic System Check.
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
3. Record and then clear DTCs.
4. Operate the vehicle within the conditions for
setting this DTC as specified in the text.

2. Move the gear shift control lever through all of the
gear ranges (P, R, N, D, 3, 2, 1).
Does the scan tool display the correct gear lever
positions?
1. Inspect the TR sensor for damage to its rotating
part or its mountings.
2. Inspect the shaft driving the TR sensor for damage.
Is a repair necessary?
Replace the TR sensor or driving shaft as appropriate.
Is the acting complete?
Check for damage to the z-link within the transmission
and repair as necessary.
Is a repair necessary?
1. Using the scan tool, clear the DTCs.
2. Road test the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool indicate that this diagnostic has
run and passed?
Check if any DTCs are set.
Are there any DTCs displayed or previously recorded
at Step 2 that have not been diagnosed?
