Inspecting the Battery
Before starting the test visually inspect the battery for:
- Cracked, buckled, or leaking case. If you see any of these defects, replace the battery.
- Corroded, loose, or damaged cables and connections. Repair or replace them as needed.
- Corrosion on the battery terminals, and dirt or acid on the case top. Clean the case and terminals using a wire brush and a mixture of water and baking soda.
- Low electrolyte level. If the electrolyte level is low, add distilled water to fill up to 1/2″ above the top of the plates and fully charge the battery. Do not overfill.
- Corroded or loose battery tray and hold-down fixture. Tighten or replace as needed.
Connecting to the Battery
Connect the charging clamps to the battery in accordance with all precautions and safety instructions. Do not connect either clamp to the vehicle’s chassis.
Connect the Red clamp to the positive ( + ) terminal and the Black clamp to the negative ( – ) terminal. An alert is displayed if the clamps are reversed on the battery terminals.
Make sure both sides of the clamps are firmly gripping the terminals. A poor connection will prevent testing, and the diagnostic charger will display the message CHECK CONNECTION. If the message re-appears after you have correctly reconnected the clamps, clean the terminals and reconnect.
Battery Test
- Connect the charger clamps to the appropriate battery posts.
- At the Main Menu, tap Advanced Battery Test. The Acquire VIN screen is displayed.
- Use a connected bar code scanner to scan the VIN bar code, usually located on the driver’s side door frame. For best results, scan the barcode located on the driver’s side door frame. A two-tone beep indicates the scan was successful. A single beep indicates the barcode was not successfully scanned.
Manual Entry: Use the on-screen keypad to manually type the 17-digit VIN — the displayed digit counter will count up the alphanumeric characters as they are entered on the keypad. Tap NEXT.
NOTE: See the Recommended Scanning Procedure article for VIN scanning help and tips.
4. At the Edit Battery Info screen, tap on the corresponding box to edit the parameter information.
NOTE: The Battery Type, Units, and Rating fields must be filled in before proceeding.
5. Tap Continue to begin the Battery Test or Reset to reset the parameters.
The test results are then displayed on the charger screen.
