Using Battery Voltage Method
- Inspect the battery as follows after removing the battery filler caps, checking the water level, and adding water to the appropriate level if needed:
| Step | Inspection | Results | Action |
|---|---|---|---|
| 1 | Measure the battery positive voltage. | 12.4 V or more | Go to Step 3. |
| Less than 12.4 V | Go to the next step. | ||
| 2 | Quick charge for 30 min and recheck voltage. | 12.4 V or more | Go to the next step. |
| Less than 12.4 V | Replace the battery. | ||
| 3 | Using the battery load tester, apply load current (See battery load test current) and record battery voltage after 15 s. Is voltage more than the specification? | Yes | Normal |
| No | Replace the battery. |
Battery load test current
55D23L (60 A.h/20HR): 180 A
75D23L (65 A.h/20HR): 195 A
Standard specification
| Battery temp. (°C {°F}) | Minimum voltage (V) |
|---|---|
| 4 {39} | 9.3 |
| 10 {50} | 9.4 |
| 16 {61} | 9.5 |
| 21 {70} | 9.6 |
Parasitic Draw Inspection:
- Verify that the ignition is switched off (lock) and all doors, the hood and the trunk/liftgate are closed.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)CAUTION:
- Operating electrical loads while the parasitic draw is being measured can damage a series-type ammeter.
- Connect the meter between the negative battery terminal and negative battery terminal. Proceed to Step 10.
- Select the DMM icon from the main menu.
- Select the DC Ammeter.
- Select the 70 AMP MAX range. (measuring milliamps)
- Connect the amp clamp to the negative battery terminal.
- Monitor the current draw.NOTE:
- If the battery is not left undisturbed for 10 min or more, but less than 30 min, the tester will indicate a high value (approx. 300 mA).
- If the ignition or any electrical accessory is operated after the tester is connected, the battery must be left undisturbed for 10 min or more, but less than 30 min from that point.
- For vehicles with the immobilizer system, the system periodically shifts synchronization of the security indicator light flashing. Therefore, 65 mA (0.1 s) current draw is supplied when the security indicator light is illuminated, and 40 mA (2 s) current draw is supplied when the security indicator light is not illuminated. In addition, the measuring instrument, which shows the average value, indicates around 55 mA.
- Leave the vehicle electrical system undisturbed for 10 min or more, but less than 30 min, and then measure the parasitic draw.
- If not within specification, measure the parasitic draw while removing the fuses one by one from the inside of the main fuse block and the inside of the fuse block.
- Inspect and repair wiring harnesses and connectors of the fuse where the current draw has decreased.
Parasitic draw (When the ignition is off (lock), all doors and the hood are closed.)
40-65 mA
NOTE:- If the battery is left for 30 min or more, a battery parasitic draw value of 25-45 mA is indicated.
