Back-up current

WARNING: This page is about a different variant/trim than selected.
  1. Verify that the ignition switch is off (key has been removed) and that all doors are closed.
  2. Disconnect the negative battery cable.
  3. Connect the tester between the negative battery terminal and negative battery cable, leave the battery undisturbed for 15 min  , 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.
    NOTE:
    • If the battery is not left undisturbed for 15 min  , the tester will indicate a high value (approx. 300 mA  ).
    • If the key or any electrical accessory is operated within approx. 15 min  after the tester is connected, the battery must be left undisturbed for approx. 15 min  from that point.
    CAUTION:
    • Operating electrical loads while the back-up current is being measured can damage the tester.
    NOTE:
    • For vehicles with the immobilizer system, the system periodically shifts synchronization of the security light flashing. Therefore, 45 mA (0.1 s)  current is supplied when the security light is illuminated, and 25 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 30 mA  .

    Battery back-up current 

    Vehicles with immobilizer system: 25-45 mA 

    Vehicles without immobilizer system: 30 mA or less 

  4. Inspect and repair wiring harnesses and connectors of the fuse where the current has decreased.
