Quiescent Current Test

1. Select Power Mode 6 (Ignition ON) and then select Power Mode 4 (vehicle unlocked and smart key present) (do not crank).
2. Open and latch all doors, hood, tailgate or luggage compartment lid.
3. Lock the vehicle using the remote function on the smart key (Single lock only to avoid volumetric sensor arming).
4. Wait until the vehicle systems have completely shut down.
   • The hazard warning lamp switch illumination or the Light Emitting Diode (LED), installed in the switch is a possible indicator of the shutdown period. When the Body Control Module (BCM)/Gateway Module A (GWM) shutdown has completed, the illumination of the hazard warning lamp switch or the LED extinguishes.
   • If none of the above listed indicators are available, wait until the specified time for shutdown period has elapsed. Refer to 'Quiescent Drain - Typical Values' in this procedure for details.
5. Record the amperage readings.
6. Record the final reading on the battery report form.

The preferred method of testing following an excessive current consumption figure is to use a current clamp around individual junction box leads to the various suspected circuits to identify a potential cause.

This is in preference to the old method of removing fuses for the following reasons:

• The drain may be caused by a module remaining active and preventing the quiescent drain from reducing to normal levels.
• The drain may be caused by a relay winding that is activated. Pulling the fuse can allow this to 'reset' and the drain will be lost and go un-diagnosed.
