No load test Voltage (V) 11
Current (A) 120 or less
(1) The headlight, rear window defroster, blower fan (2-step or more) are on.
(2) Back-up current is the constant flow of current (for audio unit, clock, PCM, etc.) that is supplied after leaving the battery undisturbed for approx. 30 min when the ignition switch is off (key has been removed) and all doors are closed.
(3) The lower limit of current must be more than 0 A.
(4) Standard equipment
(5) Hot type plug: Available only for customers who often drive their car at very low speed which causes the plugs to foul easily.
(6) Turn the following electrical loads on and verify that the voltage reading increases.
  • Headlights
