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.

Downloaded from www.Manualslib.com manuals search engine 5A-88 Automatic Transmission/Transaxle:
• With ignition switch turned to ACC position, push
shift lock solenoid release button (1). Then, select
lever can be shifted from “P” range position to any
other range.
• While ignition switch is at LOCK position, even when shift lock solenoid release button (1) is
pressed, select lever cannot be shifted from P
range position to any other range.
• When ignition switch is turned ON and brake pedal is depressed, select lever can be shifted
from “P” range position to any other range. 3) With select lever shifted to any position other than
“P” range, check that ignition key cannot be turned
LOCK position and it cannot be removed from
ignition switch unless it is at LOCK position.
Repair Instructions
Learning Control InitializationS7RS0B5106001
1) Connect san tool to DLC (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
2) Start engine and shift select lever to “P” range.
3) Select “Misc Test” mode on scan tool.

Select Cable AdjustmentS7RS0B5106013
1) Shift manual shift lever to “N” range (transmission range sensor “N” range).
2) Remove adjuster (cable end) from select lever pin of select lever assembly.
3) Release lock plate (1) which restrict moving of cable end holder (2).
4) Push cable end holder (1) out from eye-end (2) using an appropriate tool (3) to disengage cable.
5) Shift select lever to “N” position.
6) Apply grease to select lever pin and install adjuster (cable end) to it.
: Grease 99000–25011 (SUZUKI Super Grease
A)
7) With both select lever and transmission range sensor kept each “N” position, drive cable end holder
(1) in until it locks cable.
8) Slide lock plate (2) to secure cable end holder in position. 9) After select cable was
installed, check for the
following.
• Push vehicle with select lever shifted to “P” range. Vehicle should not move.
• Vehicle can not be driven in “N” range.
• Vehicle can be driven in “D”, “3”, “2” and “L” ranges.
• Vehicle can be backed in “R” range.
Key Interlock Cable Removal and InstallationS7RS0B5106014
NOTE
Don’t bend interlock cable excessively when
removing and installing it, or system will not
operate correctly.

Removal
1) If the vehicle is equipped with air bag system, disconnect negative cable at battery and disable air
bag system, referring to “Disabling Air Bag System in
Section 8B”.
2) Remove steering column cover.
3) Turn ignition switch to ACC position.
4) Pull out key interlock cable (1) from key cylinder cover (2) while pressing check hook with slotted
screwdriver (3) or the like.
