Battery Symptom Troubleshooting - Low or Dead Battery
Low or Dead Battery
NOTE:
A battery may become 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 headlights, seat heaters, wipers, rear window defogger, etc.
When measuring parasitic draw, doing the following operations may induce measurement errors:
?
With keyless access system: Approaching a vehicle with remote.
?
Locking or unlocking a door.

PGM-FI system check:

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 DTCs troubleshooting.?
     
NO
     
     
     
Go to step 2.
2.
Parasitic draw check:

Parasitic draw check
?1.
Check all the BATTERY CONSUMPTION CURRENT HISTORY with the HDS.
Threshold of the parasitic draw.
27 mA
USA and Mexico models except J35Y1 and J35Y2 engines
36 mA
Canada model except J35Y1 and J35Y2 engines
42 mA
J35Y1 and J35Y2 engines

Are all the values less than the threshold?

     
YES
     
     
     
Check the battery.?
     
NO
     
     
     
Go to step 3.

Problem verification:

Problem verification
?1.
Turn the ignition switch to LOCK (0), or 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.
Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

?7.
Check the latest BATTERY CONSUMPTION CURRENT HISTORY with the HDS.
Threshold of the parasitic draw.
27 mA
USA and Mexico models except J35Y1 and J35Y2 engines
36 mA
Canada model except J35Y1 and J35Y2 engines
42 mA
J35Y1 and J35Y2 engines

Are all the values less than the threshold?

     
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 (I) or ACC mode.
     
NO
