Subject:
INCREASED CURRENT DRAW ON AZERA AND VERACRUZ VEHICLES WITH HOOD OPEN
This bulletin is provided for informational purposes on normal vehicle operation.
DESCRIPTION:
Opening the hood on Azera and Veracruz vehicles will ground the security system's hood input switch. Grounding the hood input switch places the security system module (incorporated into the BCM) into a readiness standby mode. While in standby mode, the BCM consumes an increased amount of current that may discharge the vehicle battery if the hood is left open for several hours or overnight.
DISPLAYING OR STORING THE VEHICLE
To avoid discharging the battery while displaying the vehicle on a showroom floor (hood open), a self-regulating automatic trickle charge may be connected to the vehicle battery. If the vehicle is to be left parked with the hood open and accessory power is not required, the Power Connector on the interior fuse panel should be removed.
CURRENT DRAW TESTING
When performing key-off or parasitic current draw tests, the hood switch must be physically closed (open circuit) or disconnected to avoid inaccurate readings.
