Diagnostic Starting Point - Steering Wheel Controls

Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System Check - Vehicle will provide the following information

  1. The identification of the control modules which command the system
  2. The ability of the control modules to communicate through the serial data circuit
  3. The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check - Vehicle will identify the correct procedure for diagnosing the system and where the procedure is located.

Diagnostic Aids

Before diagnosis of the steering wheel controls, ensure the primary controls of the associated component are functioning properly.

  1. If the vehicle is equipped with RPO U2R or U2S the steering wheel controls are connected to the radio.
  2. If the vehicle is not equipped with RPO U2V or U2X the steering wheel controls are connected to the CD changer which is a serviceable component of the navigation radio.

Steering Column Accident Damage Inspection

  1. Vehicles involved in accidents resulting in frame damage, major body or sheet metal damage, or where the steering column has been impacted, or where supplemental inflatable restraint systems deployed may also have a damaged or misaligned steering column.
  2. Inspect the capsules on the steering column bracket assembly. All capsules must be securely seated in the bracket slots and checked for any loose conditions when pushed or pulled by hand.

Inflatable Restraint Steering Wheel Module Coil Centering

  1. Verify the following before centering the SIR coil: The wheels on the vehicle are straight ahead. The block tooth (1) of the steering shaft assembly is in the 12 o'clock position. The ignition switch is in the LOCK position.
  2. If the front (5) of the SIR coil has a centering window (4), and on the back side (2) a spring service lock (1), perform the following steps: Hold the SIR coil with the face up. While depressing the spring service lock, rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows (3) line up. Release spring service lock between the locking tab. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
  3. If the front (4) of the SIR coil has a centering window (3) and no spring service lock on the back side (1), perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise until the centering window appears yellow and both arrows (2) line up. This is the CENTER position. While holding the coil hub in the CENTER position, align the SIR coil with the horn tower and slide onto the steering shaft assembly.
  4. If no centering window is present on the front side (3) of the SIR coil, but a spring service lock (1) is on the back side (2), perform the following steps: Hold the SIR coil with the back side up. While depressing the spring service lock, rotate the coil hub in the direction of the arrow (4) until the coil ribbon stops. Still pressing the spring service lock, rotate the coil hub in the opposite direction 2 1/2 revolutions. Release the spring service lock between locking tabs. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
  5. For no centering window on the front side (2) of the SIR coil and no spring service lock on the back side (1), perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub in the direction of the arrow (3) until the coil ribbon stops. Rotate the coil hub, slowly, counterclockwise, for 2 1/2 revolutions. This is the CENTER position. While maintaining the coil hub in the CENTER position, align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.

Steering Wheel Controls Description and Operation

The audio steering wheel control switches duplicate the function of the primary controls of the associated component, through a network of multiple momentary contact switches and a series of resistors. The radio supplies voltage to the switches and monitors the return signal for a specific voltage drop to occur unique to the one pressed. The radio then identifies the switch selected to activate the feature, otherwise sends a serial data message that is received by the component controlled, activating the feature.

This section is intended to diagnosis the circuits between the radio and the audio steering wheel control switches. If the primary control for the device is inoperative, refer to the appropriate section for the component the steering wheel control switch is functioning.

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.

Vehicle Security-Some Vehicle Models

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

Driver Convenience

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

  1. The turn signal switch
  2. The hazard switch
  3. The headlamp dimmer switch
  4. The wiper/washer switch
  5. The horn pad/cruise control switch
  6. The redundant radio/entertainment system controls
  7. The tilt or tilt/telescoping functions
  8. The navigation/OnStar® features
  9. The HVAC controls

Driver Safety

The energy-absorbing steering column compresses in the event of a front-end collision, which reduces the chance of injury to the driver. The mounting capsules break away from the mounting bracket in the event of an accident.

Ignition Lock Cylinder Control Actuator

If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator's purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control actuator, and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when 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.
