Battery - Low Or Dead Battery
- 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:
- With keyless access system: 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 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 -29.31 mA or less?
YES
Check the battery.
NO
Go to step 3.
- Problem verification
-1. Press the engine start/stop button to select the OFF 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. Press the engine start/stop button to select the ON mode.
-7. Check the latest battery consumption current history with the HDS.
Is the value of 1 hour later -29.31 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 in the ACC mode.
NO
