Vehicle Electrical Isolation Procedure: Preparation

NOTE: This procedure might contain steps to use Toolbox 2 to supplement the service operation. Toolbox 2 and its Panels are being phased out and replaced with Toolbox 3 routines.
  1. Open the liftgate.
  2. If equipped, fold down the 3rd row seats.
  3. Disconnect 12V power. See DISCONNECT 12V POWER .
    CAUTION: Ensure that the first responder loop has been disconnected for at least 2 minutes.
  4. Set the isolation meter to measure DC high voltage, and touch the probe tips together.
    CAUTION: If the meter displays greater than 0.1 volts, the leads are defective and must be replaced.
  5. Measure the voltage across the 12V auxiliary battery terminals.
    CAUTION: If the voltage is less than 10 volts or greater than 14 volts, the multimeter is not measuring reliably and must not be used.
