DTC No. 51 / No. 52 / No. 53: Driver Side / Passenger Side / Rear End Door Request Switch FailureS7RS0BA504022
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

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.
