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.

Operation Check
Shift solenoid valve-A (No.1) and -B (No.2)
CAUTION!
• Do not insert air gun against strainer installed on inlet of solenoid valve too
deeply, when blowing air into solenoid
valve. If not, the strainer will be damaged.
• Be very careful as dust etc. does not enter when solenoid valves are inspected.

• Check that solenoid valve (1) actuate with click sound when battery voltage is conducted.
• When solenoid valve (1) is connected to battery (2), confirm that solenoid valve is close condition by
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm
2, 7 – 28.5
psi) into solenoid valve as shown in figure.
• When solenoid valve (1) is not connected to battery (2), confirm that solenoid valve is open condition by
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm
2, 7 – 28.5
psi) into solenoid valve as shown in figure.
NOTE
Do not fail to inspect with air to prevent
mistaken checking because return spring for
valve is not installe d into solenoid valve.

Timing solenoid valve
CAUTION!
• Do not insert air gun against strainer
installed on inlet of solenoid valve too
deeply, when blowing air into solenoid
valve. If not, the strainer will be damaged.
• Be very careful as dust etc. does not enter when solenoid valves are inspected.

• Check that solenoid valve (1) actuate with click sound
when battery voltage is conducted.
• When timing solenoid valve (1 ) is connected to battery
(2), confirm that timing solenoid valve is open
condition by blowing air (50 – 200 kPa, 0.5 – 2.0 kg/
cm
2, 7 – 28.5 psi) into solenoid valve as shown in
figure.
• When timing solenoid valve (1) is not connected to battery (2), confirm that timi ng solenoid valve is close
condition by blowing air (50 – 200 kPa, 0.5 – 2.0 kg/
cm
2, 7 – 28.5 psi) into solenoid valve as shown in
figure.

3) Check for gradual movement of valve (3) in the direction of arrow “A” as voltage is increased.
4) Check movement of valve (3) in the direction of arrow “B” as voltage is decreased.
5) Turn power supply switch OFF.
CAUTION!
Do not pass current 1.0 A or more, or
pressure control solenoid is burned out.

Not using regulated DC power supply 1) Connect pressure control solenoid valve (1) to battery (2) setting 21 W bulb (4) on the way as
shown in figure.
2) Check for movement of valve (3) in the direction of arrow “A”.
3) Disconnect pressure control solenoid valve (1) from battery (2) and check movement of valve (3) in the
direction of arrow “B” as shown in figure.
CAUTION!
Set 21 W bulb on the way, or pressure control
solenoid valve is burned out.

Transmission Control Module (TCM) Removal
and Installation
S7RS0B5106026
CAUTION!
• TCM and ECM consists of highly precise
parts, therefore when handling it, be
careful not to expose to excessive shock.
• When replacing TCM with used one, all learned contents, which have been stored
in TCM memory by executing learning
control, should be initialized after
replacement.

Removal
1) Disconnect negative cable at battery.
2) If the vehicle is equipped with air bag system, disable air bag system. Refer to “Disabling Air Bag
System in Section 8B”.
3) Disconnect connectors from TCM (1).
4) Remove TCM by removing its bolts.
