DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure1) Clear DTC referring to “DTC Clearance”.
2) Start engine and run it for 1 min. or more.
3) Check DTC referring to “DTC Check”.
Troubleshooting 8
DTC check of keyless start control module
1) Turn ignition switch to OFF position.
2) Disconnect connector of any one of control module other
than keyless start control module.
3) Recheck keyless start control module for DTC.
Is DTC No.31 detected? Using same method,
disconnect connectors
of control module other
than keyless start
control module one by
one to check if DTC
No.31 is detected.
If DTC No.31 is
detected even through
connector of control
module other than
keyless start control
module is disconnected,
substitute a known-
good keyless start
control module and
recheck.Check power and
ground circuit of
disconnected control
module and recheck. If
circuit is OK, substitute
a known-good
disconnected control
module and recheck.

Wiring Diagram3
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules
communicating by means of CAN.
3) Check CAN communication circuit between control modules for open, short and high resistance.
Is each CAN communication circuit in good condition? Go to Step 4. Repair circuit.
4 DTC check of keyless start control module
1) Turn ignition switch to OFF position.
2) Connect connectors of disconnected control modules
communicating by means of CAN.
3) Disconnect connector of any one control module other than keyless start control module.
4) Recheck keyless start control module for DTC.
Is DTC No.33 detected? Using same method,
disconnect connectors
of control module other
than keyless start
control module one by
one to check if DTC
No.33 is detected.
If DTC No.33 is
detected even through
connector of control
module other than
keyless start control
module is disconnected,
substitute a known-
good keyless start
control module and
recheck.Check power and
ground circuit of
disconnect control
module. If circuit is OK,
substitute a known-
good disconnected
control module and
recheck.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure1) Clear DTC referring to “DTC Clearance”.
2) Push request switch of each door.
3) Check DTC referring to “DTC Check”.
Troubleshooting DTC detecting condition Trouble area
DTC No. 51:
Input signal from driver side door request switch remains
ON, unchanged for 10 minutes or longer.
DTC No. 52:
Input signal from passenger side door request switch
remains ON, unchanged for 10 minutes or longer.
DTC No. 53:
Input signal from rear end door request switch remains
ON, unchanged for 10 minutes or longer. • Driver side door request switch and its circuit
• Passenger side door request switch and its circuit
• Rear end door request switch and its circuit
• Keyless start control module
Step
Action YesNo
1 Was “Keyless Start System Check” performed? Go to Step 2.Go to “Keyless Start
System Check”.
2 Keyless start control module voltage check
1) Turn ignition switch to OFF position.
2) Disconnect connector from each door request switch.
3) Check for proper connection to all terminals of each door
request switch connector.
4) If OK, measure voltage between “PPL”, “BLU/RED” or “YEL” terminal of related door request switch connector
and vehicle body ground.
Is voltage 10 – 14 V? Go to Step 3.
Go to Step 4.
3 Request switch check
1) Check related door request switch for function referring
to “Front Door (Driver and Passenger Side), Rear End
Door Request Switch Inspection”.
Is each switch in good condition? Substitute a known-
good keyless start
control module and
recheck.
Replace request switch.
4 Wire harness check
1) Turn ignition switch to OFF position.
2) Check for open, short and high resistance in related
circuit.
• Between “PPL” wire terminal of driver side door request switch connector and “G42-16” terminal of
keyless start control module connector
• Between “BLU/RED” wire terminal of passenger side door request switch connector and “G42-36” terminal
of keyless start control module connector
• Between “YEL” wire terminal of rear end door request switch connector and “G42-32” terminal of keyless
start control module connector
Is it in good condition? Substitute a known-
good keyless start
control module and
recheck.
Repair circuit.
