Step Action Yes No
1Fuse check
1) Turn ignition switch to OFF position.
2) Check circuit fuse and main fuse for condition.
Are fuses in good condition?Go to Step 2. Replace fuse(s) and
check for short.
2Power supply circuit check
1) Disconnect connector from keyless start control module.
2) Check for proper connection to “Power source”, “ACC
signal” and “IG ON signal” terminal of keyless start
control module connector.
3) If OK, measure voltage between following terminals.
• “Power source” terminal of keyless start control
module connector and vehicle body ground with
ignition switch is at OFF position
• “ACC signal” terminal of keyless start control module
connector and vehicle body ground with ignition
switch is at ACC position
• “IG ON signal” terminal of keyless start control module
connector and vehicle body ground with ignition
switch is at ON position
Is each terminal voltage is 10 – 14 V?Go to Step 3. Repair defective power
supply circuit.
3Ground circuit check
1) Check for proper connection to “Ground” terminal of
keyless start control module connector.
2) If OK, measure resistance between “Ground” terminal of
keyless start control module connector and vehicle body
ground.
Is resistance 1
Ω or less?Power and ground
circuit is in good
condition.Repair ground circuit.

DTC detecting condition Trouble area
No communication is available between keyless start
control module and steering lock unit.• Steering lock unit and its circuit
• Keyless start control module
Step Action Yes No
1Was “Keyless Start System Check” performed?Go to Step 2. Go to “Keyless Start
System Check”.
2Steering lock unit circuit check
1) Disconnect connector from keyless start control module.
2) Check for proper connection to “Steering lock unit power
supply”, “Steering lock unit signal” and “Steering lock unit
ground” terminals of keyless start control module
connector.
3) If OK, check for open, short and high resistance in
following circuits.
• Steering lock unit power supply circuit
• Steering lock unit signal circuit
• Steering lock unit ground circuit
Is each circuit in good condition?Go to Step 3. Repair circuit.

DTC No. 13 / No. 14: Release Signal Error from Steering Lock Unit / Steering Lock Unit MalfunctionS6RW0DA504018
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Check DTC referring to “DTC Check”.
DTC Troubleshooting
Replace steering lock unit and recheck.
NOTE
Be sure to register the following code when a used keyless start control module is installed. Otherwise
DTC No.13 is detected by keyless start control module though steering lock unit is normal.
• With immobilizer control system, ignition key transponder code is not registered in ECM.
• Without immobilizer control system, steering lock unit ID code is not registered in keyless start
control module.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Push request switch of each door.
4) Check DTC referring to “DTC Check”.
DTC Troubleshooting
Substitute a known-good keyless start control module and recheck.3Steering lock unit power supply voltage check
1) Connect connector to keyless start control module.
2) Measure voltage between “Steering lock unit power
supply” terminal of steering lock unit connector and
vehicle body ground.
Is voltage 4 – 6 V?Replace steering lock
unit.Substitute a known-
good keyless start
control module and
recheck. Step Action Yes No
DTC detecting condition Trouble area
DTC No. 13:
Although lock release signal is output to steering lock unit, no lock
release signal is inputted from steering lock unit.
(wire harness is normal)
DTC No. 14:
Although lock release signal is output to steering lock unit,
steering lock is not released due to temperature rise of steering
lock unit solenoid and no lock release signal is inputted.
(wire harness is normal)• Steering lock unit
