Inspection of TCM and Its CircuitsS7RS0B5104045
TCM and its circuits can be checked at TCM wiring connec tors by measuring voltage, pulse signal and resistance.
CAUTION!
TCM cannot be checked by itself, it is strictly prohibited to connect voltmeter or ohmmeter to TCM with
connector disconnected from it.
1) Remove TCM (1) from vehicle referring to “Transmission Control Module (TCM) Removal and Installation”.
2) Connect TCM connectors (2) to TCM.
3) Check voltage and/or pulse signal at each terminal of connectors connected using voltmeter (3) and oscilloscope
(4).
NOTE
• As each terminal voltage is affected by battery voltag e, confirm that it is 11 V or more when ignition
switch is ON.
• Voltage with asterisk(*) cannot be measured by voltmeter because it is pulse signal. Check it with oscilloscope if necessary.

Troubleshooting
Brake Interlock System InspectionS7RS0B5104047
1) Check that select lever cannot be moved to any other range from “P” range position when ignition
switch key is at ACC position, at LOCK position or it
is removed from keyhole of ignition switch, or brake
pedal is not depressed. 2) Shift select lever to “P” range position, release knob
button and check for the following.
• Ignition key can be turned between LOCK and ACC positions back and forth and also it can be
removed from ignition switch.
Step Action Yes No
1 Check TCM back-up power circuit
1) Disconnect TCM connector with ignition switch OFF.
2) Check for proper connection to TCM at “C34-24”
terminal.
3) If OK, check voltage at terminal “C34-24” of disconnected TCM connector.
Is it 10 – 14 V? Go to Step 2. “WHT/RED” circuit open
or shorted to ground.
2 Check TCM power circuit
1) Disconnect TCM connector with ignition switch OFF.
2) Check for proper connection to TCM at “C34-6” terminal.
3) If OK, turn ignition switch ON and check voltage at
terminal “C34-6” of disconnected TCM connector.
Is it 10 – 14 V? Go to Step 4. Go to Step 3.
3 Check A/T relay operation
1) Check A/T relay operation referring to “A/T Relay
Inspection”.
Is check result satisfactory? “YEL/BLK”, “YEL/BLU”,
“LT GRN/BLK” or “BLK”
circuit for power supply
open.
Replace A/T relay.
4 Check TCM ground circuit
1) Turn ignition switch OFF.
2) With TCM connectors disconnected, check for proper
connection to TCM at “C34-1” / “C34-23” terminal.
3) If OK, check resistance between “C34-1” / “C34-23” terminal of disconnected TCM connector and body
ground.
Is continuity indicated? TCM power and ground
circuits are in good
condition.
“BLK” circuit for TCM
ground open.

Centering Contact Coil Cable AssemblyS7RS0B6206004
1) Check that vehicle’s wheels (front tires) are set at straight-ahead position.
2) Check that ignition swit ch is at LOCK position.
3) Turn contact coil counterclockwise slowly with a light force till contact coil will not turn any further.
NOTE
Contact coil can turn about 5 turns at the
maximum, that is, if it is at the center
position, can turn about two and a half turns
both clockwise and counterclockwise.
4) From the position where contact coil became unable to turn any further (it stopped), turn it back clockwise
about two and a half rotations and align center mark
with alignment mark (1).
Contact Coil Cable Assembly InspectionS7RS0B6206005
Refer to “Contact Coil Cable and Its Circuit Check in
Section 8B”.
Steering Angle Sensor Removal and InstallationS7RS0B6206011
Removal

Installation” and “Contact Coil Cable Assembly
Removal and Installation”.
2) Remove steering angle sensor (2) from contact coil cable assembly (3) while op ening fitting parts (1) of
contact coil cable assembly.
Installation 1) Install steering angle sensor (2) by fitting engagement parts (1) of contact coil cable assembly
to claws of steering angle sensor as shown in figure.
2) Install contact coil cable assembly and steering wheel. Refer to “Contact Coil Cable Assembly
Removal and Installation” and “Steering Wheel
Removal and Installation”.

Precautions
Steering System NoteS7RS0B6300001
NOTE
All steering gear fasteners are important attaching parts in that they could affect the performance of
vital parts and systems, and/or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of these parts.
Precautions in Diagnosing TroublesS7RS0B6300002
• Take a note of DTC indicated on the SUZUKI scan tool.
• Before inspection, be sure to read “Pre cautions for Electrical Circuit Service in Section 00” and understand what is
written there.
• DTC C1122 (engine speed signal failure) is indicated when ignition switch is at ON position and engine is not
running, but it means there is nothing abnormal if indica tion changes to a normal one when engine is started.
• As DTC is stored in memory of the P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC Clearance”.
