1. Keyless start control module 4. Main fuse
2. Ignition switch
Step Action Yes No
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 position
Between “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.
