Step Action YesNo
1 Fuse 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.
2 Power supply circuit check
1) Disconnect connector from keyless start control module.
2) Check for proper connection to “G42-10”, “G42-11” and
“G42-15” terminals of keyless start control module
connector.
3) If OK, measure voltage between the following terminals. • When ignition switch is at OFF positionBetween “G42-10” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ACC position Between “G42-11” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ON position Between “G42-15” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
Is check result satisfactory? Go to Step 3.
Repair power supply
circuit.
3 Ground circuit check
1) Check for proper connection to “G42-9” terminal of
keyless start control module connector.
2) If OK, measure resistance between “G42-9” 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 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.

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
