Troubleshooting

1. Fuse check

Turn ignition switch to OFF position.
Check circuit fuse and main fuse for condition.

Are fuses in good condition?
YES -
Go to Step 2.
NO -

Check for proper connection to "Power source", "ACC signal" and "IG ON signal" terminal of keyless start control module connector.
If OK, measure voltage between following terminals.
- "Power source" terminal of keyless start control module connector and vehicle body ground with ignition switch is at OFF position
- "ACC signal" terminal of keyless start control module connector and vehicle body ground with ignition switch is at ACC position
- "IG ON signal" terminal of keyless start control module connector and vehicle body ground with ignition switch is at ON position

Is each terminal voltage is 10 - 14 V?
YES -
Go to Step 3.
NO -
Repair defective power supply circuit.

3. Ground circuit check

Check for proper connection to "Ground" terminal of keyless start control module connector.
If OK, measure resistance between "Ground" terminal of keyless start control module connector and vehicle body ground.

Is resistance 1 ohms or less?
YES -
Power and ground circuit is in good condition.
NO -
Repair ground circuit.
