DTC Troubleshooting

1. Battery voltage check

Check battery voltage.

Is voltage in 9 - 16 V?
YES -
Go to Step 2.
NO -
Check charging system and repair it. Testing and Inspection

2. SDM connection check

Check for proper connection to SDM connector.

Is it connected securely?
YES -
Go to Step 3.
NO -
Intermittent trouble. Check for intermittent trouble. Intermittent Connection and Poor Contact Inspection
If OK, substitute a known-good SDM and recheck connection. SDM Removal and Installation

3. Fuse check

Confirm that ignition mode of keyless push start system is in "OFF".
Check "A/B" fuse.

Is "A/B" fuse in good condition?
YES -
Go to Step 4.
NO -
Replace defective harness and then replace "A/B" fuse.

4. Power circuit check

Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "L04" connector.
Push engine switch to change ignition mode of keyless push start system to "ON".
Measure voltage between "L04-18" terminal and ground.

Is voltage in 10 - 14 V?
YES -
Go to Step 5.
NO -
Replace defective harness.

5. Ground circuit check

Confirm that ignition mode of keyless push start system is in "OFF".
Measure resistance between "L04-23" terminal ground.
Special Tool

(A): 09932-76010





Is resistance 1 ohms or less?
YES -
SDM power circuit and ground circuit are in good condition.
NO -
Replace defective harness.
