Diagnostic Instructions

  1. Perform the «Diagnostic System Check - Vehicle»(/cadillac/srx/ii-2009-2012/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures) prior to using this diagnostic procedure.
  2. Review «Strategy Based Diagnosis»(/cadillac/srx/ii-2009-2012/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures__strategy-based-diagnosis) for an overview of the diagnostic approach.
  3. «Diagnostic Procedure Instructions»(/cadillac/srx/ii-2009-2012/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures__diagnostic-procedure-instructions) provides an overview of each diagnostic category.

Circuit/System Description

The vehicle theft deterrent subsystem provides the capability to lock or unlock the steering electrically. The steering column lock control module is allowed to unlock when power mode transitions to a non off power mode and an authenticated driver identification device is present. Once the column is unlocked, a crank request can be allowed.

Conditions for Running the DTC

  1. The ignition is in OFF, ACCESSORY or RUN position.
  2. The system voltage is between 9-16 V.

Conditions for Setting the DTC

The steering column lock control module detects an internal sensor malfunction resulting in lock status of invalid to be transmitted on serial data.

Action Taken When the DTC Sets

  1. DTC B1023 is stored in memory.
  2. The driver information center displays the service column lock system warning message.
  3. The steering column lock indicator is ON.

Conditions for Clearing the DTC

  1. No steering column lock control module internal sensor malfunction so lock status of valid is transmitted on serial data.
  2. The condition for setting the DTC is no longer present.

Steering Wheel and Column Description and Operation

The steering wheel and column has 4 primary functions

  1. Vehicle steering
  2. Vehicle security
  3. Driver convenience
  4. Driver safety

Vehicle Steering

The steering wheel is the first link between the driver and the vehicle. The steering wheel is fastened to a steering shaft within the column. At the lower end of the column, the intermediate shaft connects the column to the steering gear.

The steering column can be adjusted vertically and longitudinally.

Vehicle Security

Theft deterrent components are mounted and designed into the steering column. The following components allow the column to be locked in order to minimize theft

  1. The ignition switch
  2. The steering column lock
  3. The ignition cylinder
  4. The theft deterrent immobilizer module, if equipped

Driver Convenience

The steering wheel and column may also have driver controls attached for convenience and comfort. The following controls may be mounted on the steering wheel or column.

  1. The turn signal switch
  2. The headlamp dimmer switch
  3. The wiper/washer switch
  4. The horn pad
  5. The redundant radio/entertainment system controls
  6. The tilt functions
  7. The telephone system controls
  8. The driver information center controls
  9. The cruise control functions
  10. The automatic transmission manual setting function

Driver Safety

The steering wheel and column has safety features to protect the driver. The following components may be mounted on or near the steering column

Energy Absorbing Steering Column

The energy absorbing steering column compresses in the event of a front-end collision, which reduces the chance of injury to the driver. The energy absorbing feature, collapsible steering shaft, and break away mounting features help reduce the injury in the event of an accident.

SIR Coil and Module

For additional information on the operation of the SIR coil and module, refer to SIR System Description and Operation .

Electronic Park Lock/Ignition Lock Cylinder Control Actuator

If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column. Depending on the implementation, logic might be inverted: Key can be removed by power off.

Steering Wheel Angle Sensor

The steering wheel angle sensor is located somewhere along the steering shaft assembly. The sensor measures the position of the steering wheel and the speed at which it is rotated. A signal representing this measurement is provided to the vehicle stability enhancement system in the ABS module and to the variable effort steering system.

The Theft Deterrent Immobilizer Module

The immobilizer module is mounted in the steering column lock on cars without Passive Entry Passive Start system. Refer to Content Theft Deterrent (CTD) Description and Operation .
