BCM Scan Tool Data Definitions

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

Column Feedback

The scan tool displays Active or Inactive. When the steering column lock motor is LOCKED, the scan tool will display Inactive. When the steering column lock motor is UNLOCKED, the scan tool displays Active.

Column Lock State

The scan tool displays the current column lock state. This data represents what column lock functional mode the BCM is in. The BCM enters different column lock states based upon information received from various inputs associated with the column lock system.

Column Lock/Unlock A

The scan tool displays Active or Inactive. When the BCM LOCKS the steering column, the scan tool will display Active. When the BCM UNLOCKS the steering column, the scan tool displays Inactive.

Column Lock/Unlock B

The scan tool displays Active or Inactive. When the BCM UNLOCKS the steering column, the scan tool will display Active. When the BCM LOCKS the steering column, the scan tool displays Inactive.

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.).

Driver Door Ajar Switch

The scan tool displays Open or Closed. When the driver door is open, the scan tool will display Open. When the driver door is closed, the scan tool displays Closed.

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 like 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 like RAP, wake-up, etc.

Ignition 3

The scan tool displays ON or OFF. When the BCM detects ignition 3 is present, the scan tool will display Yes. When the BCM does not detect ignition 3, 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 like 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 of 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.

Passenger Door Ajar Switch

The scan tool displays Open or Closed. When the passenger door is open, the scan tool will display Open. When the passenger door is closed, the scan tool displays Closed.
