BCM Scan Tool Data Definitions

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

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 rely on this information to preform certain functions (RAP, wake-up, etc.).

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 rely 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 rely 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 rely 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.

LDCM Scan Tool Data Definitions

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

Battery 2: The scan tool displays 0-26 volts. The value displayed is the voltage available at the SCM battery 2 input.

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

Forward Position Motor Stop: The scan tool displays 0-5 volts. The value displayed is the fore/aft position sensor signal voltage where the seat forward movement will stop. This function may be used to determine if the adjustment range of the fore/aft motor has been limited due to an obstruction or binding condition.

Front Down Position Motor Stop: The scan tool displays 0-5 volts. The value displayed is the front vertical position sensor signal voltage where the seat front down movement will stop. This function may be used to determine if the adjustment range of the front vertical motor has been limited due to an obstruction or binding condition.

Front Up Position Motor Stop: The scan tool displays 0-5 volts. The value displayed is the front vertical position sensor signal voltage where the seat front up movement will stop. This function may be used to determine if the adjustment range of the front vertical motor has been limited due to an obstruction or binding condition.

Front Vertical Position: The scan tool displays 0-255 counts. The counts displayed represent the seat front vertical position sensor signal voltage. The counts will vary as the seat front is moved up or down.

Horizontal Position: The scan tool displays 0-255 counts. The counts displayed represent the seat fore/aft position sensor signal voltage. The counts will vary as the seat is moved forward or backward.

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

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

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

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

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