Scan Tool Data Definitions - Data

BATTERY VOLTAGE: The scan tool displays the battery system voltage.

INADVERTENT POWER TIMER: The scan tool displays the seconds left before the BCM turns the inadvertent power relay OFF. The BCM uses this feature to protect the battery against inadvertent battery rundown caused by components that are part of the courtesy lamp circuit. The inadvertent power relay is supplied power by the BCM for 2400 seconds (approximately 40 minutes), after the ignition is turned OFF.

RETAINED ACCESSORY POWER (RAP) TIMER: The scan tool displays the seconds left before the BCM turns the RAP relay OFF. The BCM uses this feature to allow the operation of the radio and the power windows for up to 1198 seconds (approximately 20 minutes), after the ignition is turned OFF. After the time has elapsed or the door is opened the BCM will open the ground circuit for the RAP relay.
