SCLCM Scan Tool Data Definitions

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

Battery Voltage Signal

The scan tool displays 0-20 volts. The scan tool displays the voltage as received on the battery positive voltage circuit of the module.

Column Feedback Signal

The scan tool displays 0-5 volts. This data represents the signal received on the column lock motor signal circuit.

Column Lock Enable Signal

The scan tool displays Enabled or Disabled. This signal determines whether or not the body control module (BCM) is allowing the SCLCM to function.

Column Lock Module Status

The scan tool displays Enabled or Disabled, whether or not the SCLCM is functioning.

Column Lock Motor Command

The scan tool displays Lock, Unlock or No Action. This data shows what the SCLCM is commanding the column lock motor.

Column Lock Motor Status

The scan tool displays Lock, Unlock, No Action or Undefined. This data shows what the column lock motor is doing.

Column Lock Status

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

Ignition Voltage Signal

The scan tool displays ON or OFF. When the SCLCM detects ignition is present, the scan tool will display On. When the SCLCM does not detect ignition, the scan tool will display OFF. This ignition switch information is hard wired into the SCLCM.

Park Switch

The scan tool displays On or Off. When the transmission is placed in PARK the scan tool displays On and when the transmission is out of PARK the scan tool displays Off.

Password Status

The scan tool displays Valid, Invalid or Not Programmed. The SCLCM compares the password it has to the password in the remote control door lock receiver (RCDLR) via class 2. When the password is the same then the scan tool displays Valid and when the password is different then the scan tool displays Invalid. When the SCLCM is has not been programmed the seed and key procedure to program the module has not been performed.
