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.
