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.

NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

2 1) With ignition switch OFF, disconnect SDM connector.2) Check proper connection to SDM at “L29-27” terminal.
3) If OK, turn ignition switch ON and then check voltage between “L29-27” terminal on SDM connector and body
ground.
Special tool
(A): 09932-76010
Is voltage 8 V or more? Go to Step 4. Go to step 3.
3 1) With ignition switch OFF, disconnect on connector “L04” junction block assembly.
2) Check proper connection at “L04-1” terminal.
3) If OK, turn ignition switch ON and then check voltage between “L04-1” terminal and body ground.
Is voltage 8 V or more? Go to Step 4. Check circuit from
battery to “L04”
connector and charging
system.
4 1) With ignition switch OFF, reconnect SDM connector. With ignition switch ON, does DTC B1017 exist? Substitute a known-
good SDM and recheck.
Check charging system
and repair as necessary
referring to “Generator
Test (Undercharged
Battery Check) in
Section 1J”.

DTC Detecting Condition and Possible Cause
Flow Test Description
Step 1: Check air bag communication circuit.
Step 2: Check air bag communication circuit.
Step 3: Check air bag communication circuit. 2
Check outside air temperature sensor circuit
1) Turn ignition switch to ON position.
2) Measure voltage between “E14-2” terminal of outside air
temperature sensor connector and vehicle body ground.
Is voltage 4 – 6 V? Go to Step 3. Open or short in “YEL/
RED” wire circuit. If OK,
substitute a known-
good BCM (included in
junction block
assembly) and recheck.
3 Check outside air temperature sensor circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to “E46-8” terminal of BCM
connector.
3) If OK, measure resistance between “E14-1” terminal of outside air temperature sens or connector and vehicle
body ground.
Is resistance 1
Ω or less? Substitute a known-
good BCM (included in
junction block
assembly) and recheck.
Open or high resistance
in “YEL/BLK” wire
circuit.
