12 VOLT BATTERY SYMPTOM TROUBLESHOOTING - LOW OR DEAD 12 VOLT BATTERY

Low or Dead 12 Volt Battery

NOTE:

  • A 12 volt 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

Electrical System - Testing & Troubleshooting

1. PGM-FI system check.

  1. Check for PGM-FI DTCs.

Electrical System - Testing & Troubleshooting

Are DTCs P0562, P065A, and/or P16BB indicated?

YES

Go to indicated DTCs troubleshooting.

  • DTC P0562
  • DTC P065A
  • DTC P16BB

NO

Go to step 2.

2. Parasitic draw check.

  1. Check all the BATTERY CONSUMPTION CURRENT HISTORY with the HDS.

Battery Consumption Current History

Are all the values of average current from 1 hour to 2 hours -30 mA or less?

YES

Check the 12 volt battery.

NO

Go to step 3.

3. Problem verification.

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Get out of the vehicle, and close all doors and tailgate securely.
  3. Lock the doors with the keyless transmitter or remote.
  4. Make sure the front individual map light are turned off and the security alarm system is armed.
  5. Wait 130 minutes or more.
  6. Turn the vehicle to the ON mode.
  7. Check the latest BATTERY CONSUMPTION CURRENT HISTORY with the HDS.

Battery Consumption Current History

Is the values of average current from 1 hour to 2 hours -30 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 ACCESSORY mode.

NO

Go to the parasitic draw check.

    The base current is a basic current value to drive the motor. Base current is calculated using steering torque and vehicle speed. EPS motor torque tends to be lower as the vehicle begins to move, and higher as it decreases in speed due to inertia of the rotating body. Inertia compensation increas
