Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Standby Current
- Prepare the circuit tester which can measure down to 1 mA.NOTE:
For model with keyless access function, the standby current changes regularly. Therefore, prepare the analog type circuit tester.
- Using the circuit tester, check the standby current.NOTE:
The standby current may be displayed lower than the actual value if the battery is weak, so charge or replace the battery as necessary.
- Check the battery.

- Check that the fuse is not blown out and is properly inserted.
- When non-genuine electrical parts (including parts sold in authorized workshops) are installed, remove all parts.
- Check that back-up fuse is inserted. Ref. to PRE-DELIVERY INSPECTION>PRE-DELIVERY INSPECTION (PDI) PROCEDURE>FUSE INSTALLATION .
- Start the engine, and set the switch positions for each system as shown in the following table.NOTE:
Some of the listed systems are not equipped depending on the vehicle. Set only the systems equipped on the vehicle to the positions as shown.
System Position Headlight ON or Auto Fog light ON Wiper (front and rear) ON or Low speed Audio and navigation system ON Rear defogger ON Room light DOOR Luggage light DOOR Map light OFF Auto A/C ON (AUTO) Manual A/C ON (Speed 1) Electronic parking brake ON Electrical parts other than listed above (electrical parts that users can confirm the operation with the key removed) OFF - Turn the ignition switch to OFF.
- Operate the front hood lock release lever to unlock the front hood.
- Close all the doors (including rear gate and trunk lid) and then lock the doors. (Security alarm is in set condition)NOTE:
For model with keyless access function, take the access key 1.5 m or more away from the vehicle after the door lock. And do not put the access key close to the vehicle while measuring the standby current.
- Wait for 5 minutes after door lock until the standby current stabilizes.
- Loosen the nut which holds the ground terminal to the battery sensor.NOTE:
Do not remove the ground terminal.
- Connect the circuit tester positive terminal to the ground terminal.NOTE:
To prevent the damage to the circuit tester, set the circuit tester range to a large value first, then gradually change it to smaller values.
- Connect the circuit tester negative terminal to the ground terminal installation part of the battery sensor.
- While connecting the circuit tester positive terminal with the ground terminal as shown in the figure, remove the ground terminal from the battery sensor.
- Check the standby current.CAUTION:
If the terminals and circuit tester are detached during standby current inspection, reconnect the ground terminal to the battery sensor and repeat the procedure from step (9).
- Check the battery.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
