-
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 2.5 hours from that point.
-
For vehicles with the immobilizer system, the system periodically shifts synchronization of the security light flashing. Therefore, 65 mA (0.1 s)
current is supplied when the security light is illuminated, and 40 mA (2 s) current is supplied when the security light is not illuminated. In
addition, the measuring instrument, which shows the average value, indicates around 55 mA.
4. Connect the tester between the negative battery terminal and negative battery cable, leave the battery undisturbed for 10 min or more, but less
than 2.5 hours, and then measure the back-up current.
-
If not within the specification, measure the back-up current 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 has decreased.
Battery back-up current (When the ignition is off (key is removed) and all doors are closed.)
-
40-65 mA
NOTE:
-
If the battery is left for 2.5 hours or more, a battery back-up current value of 25-45 mA is indicated.
