DPM Scan Tool Data Definitions

The driver position module (DPM) Scan Tool Data Definitions contains a brief description of all steering column related DPM parameters available on the scan tool.

Default Telescope Exit Position: The scan tool displays the default voltage value for the telescope operation in the exit position.

Default Tilt Exit Position: The scan tool displays the default voltage value for the tilt operation in the exit position.

Memory 1 Telescope Exit Position: The scan tool displays 0-5 volts. The value displayed is the telescope sensor voltage stored by the DPM and is used to recall the telescope exit position for driver 1.

Memory 1 Telescope Position: The scan tool displays 0-5 volts. The value displayed is the telescope sensor voltage stored by the DPM and is used to recall the telescope position for driver 1.

Memory 1 Tilt Exit Position: The scan tool displays 0-5 volts. The value displayed is the tilt sensor voltage stored by the DPM and is used to recall the tilt exit position for driver 1.

Memory 1 Tilt Position: The scan tool displays 0-5 volts. The value displayed is the tilt sensor voltage stored by the DPM and is used to recall the tilt position for driver 1.

Memory 2 Telescope Exit Position: The scan tool displays 0-5 volts. The value displayed is the telescope sensor voltage stored by the DPM and is used to recall the telescope exit position for driver 2.

Memory 2 Telescope Position: The scan tool displays 0-5 volts. The value displayed is the telescope sensor voltage stored by the DPM and is used to recall the telescope position for driver 2.

Memory 2 Tilt Exit Position: The scan tool displays 0-5 volts. The value displayed is the tilt sensor voltage stored by the DPM and is used to recall the tilt exit position for driver 2.

Memory 2 Tilt Position: The scan tool displays 0-5 volts. The value displayed is the tilt sensor voltage stored by the DPM and is used to recall the tilt position for driver 2.

Telescope Forward Command: The scan tool displays the On or Off. The scan tool displays On when the DPM commands the telescope actuator forward.

Telescope Forward Switch: The scan tool displays Active or Inactive. When the switch is pressed to the forward position the scan tool displays Active. When the switch is not depressed forward the scan tool displays Inactive.

Telescope Rearward Command: The scan tool displays On or Off. The scan tool displays On when the DPM commands the telescope actuator rearward.

Telescope Rearward Switch: The scan tool displays Active or Inactive. When the switch is pressed to the rearward position the scan tool displays Active. When the switch is not depressed rearward the scan tool displays Inactive.

Telescope Sensor: The scan tool displays 0-5 volts. The value displayed is the telescope sensor signal voltage. This voltage varies when the steering column is moved forward or rearward and is used by the DPM to determine the steering column position when memory settings are stored and recalled.

Tilt Down Command: the scan tool displays On or Off. The scan tool displays On when the DPM commands the tilt actuator down.

Tilt Down Switch: The scan tool displays Active or Inactive. When the switch is pressed to the down position the scan tool displays Active. When the switch is not depressed down the scan tool displays Inactive.

Tilt Sensor: The scan tool displays 0-5 volts. The value displayed is the tilt sensor signal voltage. This voltage varies when the steering column is moved up or down and is used by the DPM to determine the steering column position when memory settings are stored and recalled.

Tilt Up Switch: The scan tool displays Active or Inactive. When the switch is pressed to the up position the scan tool displays Active. When the switch is not depressed up the scan tool displays Inactive.

BCM Scan Tool Data Definitions

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

Column Lock Relay Command: The scan tool displays On/Off. The state displayed is the command state of the lock enable relay. This function is controlled by the BCM with data from the remote control door lock receiver (RCDLR).

Column Lock Relay Signal: The scan tool displays On/Off. The state displayed is the actual state of the lock enable relay. This function is controlled by the BCM with data from the RCDLR.
