DESCRIPTION
The Mazda DCA-8000 is required for all warranty battery testing. If the Mazda DCA-8000 is not used, incorrect battery
testing may result in unnecessary battery replacement. Use the following test procedures in this Service Bulletin to test
Mazda vehicle batteries and to generate a Warranty Code.
NOTE: A Warranty Code is required for warranty claim submission
Battery Identification (Mazda batteries have 2 rating types)
1. JIS (Japanese Industrial Standard):
JIS codes are six-digit alpha-numeric markings molded into the top of the battery to identify a battery by the capacity
(amps), dimensions, and battery terminal type. Vehicles manufactured in Japan come from the factory with a JIS rated
battery.
NOTE: Replacement batteries may use a CCA rating. If so, use the CCA rating listed on the battery.

2. CCA (Cold Cranking Amps):
CCA ratings are normally located on a sticker affixed to the top of the battery to indicate a battery’s Cold Cranking Amps.
CCA rated batteries are supplied with domestically produced vehicles.
NOTE: If an incorrect CCA rating is entered into the Mazda DCA-8000, it will result in a false result and invalid Warranty
Code from the tester. This will also result in unnecessary replacement of batteries.
TEST PROCEDURE
Mazda DCA-8000 Main Menu

1. Connect the charger clamps to the appropriate battery posts.
2. At the Main Menu, select In Vehicle Charge and the Acquire VIN screen is displayed.
3. Scan the barcode located on the driver’s side door frame using the provided wireless barcode scanner. A
single beep indicates the scan was successful.
NOTE:
• If the DCA-8000 isn't used very often, the scanner might go dead because it only
charges when the unit is plugged in and on.
• If your barcode scanner is unavailable for some reason, the VIN can also be entered
manually.
• If the battery parameters were not filled in from the VIN scan, manually enter the
battery information.
• Select the correct rating system for the battery by identifying the correct JIS code (A)
stamped onto the batter top or CCA code (B) printed on the battery label. The battery
hold down may need to be removed in order to read the JIS code.
• For MX-30, the battery does not follow Japanese Industrial Standard, therefore input
CCA of 295A.
