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 Aft 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. The stop can be recalibrated by pressing switch 6-8 times in one direction.
Column Fore 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. The stop can be recalibrated by pressing switch 6-8 times in one direction.
Column Fore/Aft Motor: The scan tool displays In, Out, or Idle. When the SCM supplies voltage to operate the steering column motor In the scan tool displays In and when the SCM supplies voltage to operate the steering column motor out the scan tool displays Out. This may occur with switch operation or memory operation. When SCM is not supplying voltage to the motor the scan tool displays Idle.
Column Fore/Aft Switch: The scan tool displays In, Out, or Idle. When the Column Fore/Aft Switch is pressed toward the I/P the scan tool displays Out. When the switch is pressed toward the driver the scan tool displays In. When the switch is released the scan tool displays Idle.
Column Position Fdbk: 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.
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.
