BCM Scan Tool Data Definitions

The BCM Scan Tool Data Definitions contains a brief description of all BCM related parameters available on the scan tool.

Battery Volts: The scan tool displays the battery voltage to the BCM.

Calibration Version : The scan tool displays the BCM calibration version number for service identification.

Controller Part Number : The scan tool displays the BCM part number for service identification.

Current Power Mode : The scan tool displays the current power mode. The BCM determines ignition switch position from it's ignition inputs. This ignition switch information is sent on the serial data line to systems that relay on this information to preform certain functions (RAP, wake-up, etc.).

EEPROM Calibration ID : The scan tool displays the BCM EEPROM calibration number for service identification.

Hardware Version : The scan tool displays the BCM hardware version number for service identification.

Ignition 1 : The scan tool displays ON or OFF. When the BCM detects ignition 1 is present , the scan tool will display Yes. When the BCM does not detect ignition 1, the scan tool will display OFF. This ignition switch information is sent on the serial data line to systems that relay on this information to preform certain functions (RAP, wake-up, etc.).

Ignition 2 : The scan tool displays ON or OFF. When the BCM detects ignition 2 is present , the scan tool will display Yes. When the BCM does not detect ignition 2, the scan tool will display OFF. This ignition switch information is sent on the serial data line to systems that relay on this information to preform certain functions (RAP, wake-up, etc.).

Key-In-Ignition : The scan tool displays Active or Inactive. When the BCM detects the key is IN the ignition switch, the scan tool will display Active. When the key is removed from the ignition switch, the scan tool will display Inactive.

Key Out Ignition : The scan tool displays Active or Inactive. When the BCM detects the key is OUT of the ignition switch, the scan tool will display Active. When the key is IN the ignition switch, the scan tool will display Inactive.

Software Major Version : The scan tool displays the BCM major software version number for service identification.

Software Minor Version : The scan tool displays the BCM minor software version number for service identification.
