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.

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.).

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 (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.

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.

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.

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. Refer to Steering.

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/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.

LDCM Scan Tool Data Definitions

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

Door Ajar: The scan tool displays Closed or Ajar. When the driver door is open the scan tool will display ajar. When the driver door is closed the scan tool will display Closed.

Memory 1 Select Switch: The scan tool displays Active or Inactive. When the memory 1 switch is pressed the scan tool will display Active. When the switch is released the scan tool will display Inactive.

Memory 2 Select Switch: The scan tool displays Active or Inactive. When the memory 2 switch is pressed the scan tool will display Active. When the switch is released the scan tool will display Inactive.

SCM Scan Tool Data Definitions

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

Column Position Feedback: The scan tool displays 0-5 volts. The value displayed is the telescoping column position sensor signal voltage. This voltage varies when the steering column is moved In and Out and is used by the SCM to determine the steering column position when memory settings are stored and recalled.

Column In/Out Switch: The scan tool displays Active or Inactive. When the column In/Out switch is pressed in either direction the scan tool displays Active. When the switch is released the scan tool displays Inactive.

Column In/Out Motor: The scan tool displays Active or Inactive. When the SCM supplies voltage to operate the steering column motor In or Out the scan tool displays Active. This may occur with switch operation or memory operation.

Column Out Motor Stop: The scan tool displays 0-5 volts. The value displayed is the position sensor signal voltage where the steering column outward movement will stop. This function may be used to determine if the adjustment range of the steering column has been limited due to an obstruction or binding condition.

Column In Motor Stop: The scan tool displays 0-5 volts. The value displayed is the position sensor signal voltage where the steering column inward movement will stop. This function may be used to determine if the adjustment range of the steering column has been limited due to an obstruction or binding condition.

Memory 1 Stored Position: The scan tool displays 0-5 volts. The value displayed is the position sensor signal voltage stored by the SCM and used to recall the memory 1 position.

Memory 2 Stored Position: The scan tool displays 0-5 volts. The value displayed is the position sensor signal voltage stored by the SCM and used to recall the memory 2 position.

Memory 3 Stored Position: The scan tool displays 0-5 volts. The value displayed is the position sensor signal voltage stored by the SCM and used to recall the memory 3 position.
