Low or Dead Battery
NOTE:
- A battery might be discharged under these conditions:
-
- Driving a vehicle 6 miles (10 km) or less per day.
- Leaving a vehicle idling with high electrical loads such as headlight, seat heaters, wipers, rear window defogger, etc.
- When doing the following operation during the measurement of the parasitic draw, it may not be measured accurate:

- Approaching a vehicle with remote.
- Locking or unlocking a door.
Indication Example
| - Latest History - |
| Duration: 72 * hours |
| Data | Value |
|---|---|
| IG-OFF | -439. 65 mA |
| 1 hour later | -19. 54 mA |
| 2 hours later | -29. 31 mA |
| 72 * hours later | -19. 54 mA |
*: The value that just before the vehicle ignition is in ON mode is shown. The value varies depending on when the vehicle ignition is in ON mode.
- PGM-FI system check
- 1. Check for PGM-FI DTCs.
DTC Description Confirmed DTC Pending DTC P0562 CHARGING SYSTEM LOW VOLTAGE P065A ACG NO CHARGING MALFUNCTION P16BB ALTERNATOR B TERMINAL CIRCUIT LOW VOLTAGE Are DTCs P0562, P065A, and/or P16BB indicated?
YES
Go to indicated DTC troubleshooting.
NO
Go to step 2.
- Parasitic draw check
- 1. Check all the battery consumption current history with the HDS.
Are all the values of 1 hour later -48. 85 mA or less?
YES
Check the battery.
NO
Go to step 3.
- Problem verification
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Get out of the vehicle, and close all doors and trunk securely.
- 3. Lock the doors with the keyless remote.
- 4. Make sure the individual map lights are turned off and the security alarm system is armed.
- 5. Wait 70 minutes or more.
- 6. Turn the vehicle to the ON mode.
- 7. Check the latest battery consumption current history with the HDS.
Is the value of 1 hour later -48. 85 mA or less?
-
YES
Intermittent failure, the system is OK at this time. The possible cause could be that an incorrect parasitic draw value was recorded:
- A switch was not turned off.
- The vehicle's accessories were operated for a long time with the vehicle ignition was in the ACCESSORY mode.
NO
Go to the parasitic draw check - Refer to: Parasitic Draw Check (2014 2015), or Parasitic Draw Check (2016 2017 2018 2019 2020) .
