      NOTE:
      • Make sure to check the polarity of each terminal (positive (+) or negative (-)) before connecting a tester.
      • Read the resistance after the value has stabilized.
      • In order to avoid damaging the terminals of the battery ECU assembly, make sure to use tester probes with a diameter of approximately 0.5 mm (0.0197 in.) when measuring the resistance of the battery ECU assembly.
