  1. Open all the doors and lower all the windows.
  2. Remove the rear underhood apron. See Faldón del vano del motor - Parte trasera (Desinstalación y sustitución).
  3. Disconnect 12V/LV power. See Alimentación de 12 V/baja tensión (Desconexión y conexión).
  4. Set the current clamp to measure voltage , and then measure the voltage across the 12V/LV auxiliary battery terminals using the test probes.
    Informational PurposesAn informational icon, calling your attention
    Nota
    For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is 0, the battery may have switched off internally. Use a 12V Lead Acid battery for testing. For mobile technicians: use the 12V Lead Acid battery in the Mobile Service vehicle.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    PRECAUCIÓN
    For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is less than 13 volts or greater than 16 volts, the current clamp is not measuring reliably and must not be used.
