Steering Column Tilt Function Inoperative

Circuit Description

If the vehicle is equipped with a floor mounted console gearshift, an ignition lock cylinder control actuator system is used in the steering column. The purpose of the system is to prevent the ignition lock cylinder from being turned to the lock position while the transmission is in gear, this also prevents the steering wheel from being locked. The system consists of an ignition lock cylinder actuator and a park position switch. The actuator contains a pin that is spring loaded out, to prevent the ignition lock cylinder from being turned to the lock position when the gearshift is not in Park. The park position switch is located in the floor mounted gearshift assembly, as part of the automatic transmission shift lock control switch. The switch is closed with the gearshift in PARK, and open in all other positions.

System Operation

When the gearshift is in the PARK position, the park position switch is closed. This applies voltage to the ignition lock cylinder actuator and the pin retracts, allowing the ignition lock cylinder to be turned to the LOCK position. When the gearshift is not in PARK, the park position switch is open. No voltage is applied to the ignition lock cylinder actuator and the spring loaded pin remains in the out position, preventing the ignition lock cylinder from being turned to LOCK. If vehicle power is lost while the ignition lock cylinder is not in the LOCK position, the system will prevent the operator from turning the ignition key to the lock position or removing the key. If the vehicle has lost power, pushing the ignition lock cylinder release button on the underside of the ignition lock cylinder will override the system and allow the key to be removed.

Scheme 6: Inflatable Restraint Steering Wheel Module Coil Centering
  1. Verify the following conditions before centering the SIR coil: The wheels on the vehicle are pointed straight ahead. The block tooth (1) of the steering shaft is in the 12 o'clock position. The ignition switch is in the LOCK position, or J 42640 is installed in the upper tilt head.
  2. If the front (5) of the SIR coil has a centering window (4), and the back side (2) has a spring service lock (1), perform the following steps: Hold the 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, counter clockwise, until the centering window appears yellow and both arrows (3) line up. Release the spring service lock between the locking tab. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide the coil onto the steering shaft.
  3. If the front (4) of the SIR coil has a centering window (3) and the back side (1) does NOT have a spring service lock, perform the following steps: Hold the coil with the face up. Rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counter clockwise until the centering window appears yellow and both arrows (2) line up. This is center position. While holding the coil hub in center position, align the SIR coil assembly with the horn tower and slide onto the steering shaft.
  4. If the front side (3) of the SIR coil does NOT have a centering window, but the back side (2) has a spring service lock (1), perform the following steps: Hold the SIR coil with the back side up. While depressing the spring service lock, rotate the coil hub counter clockwise until the coil ribbon stops. Still pressing the spring service lock, rotate the coil hub in the opposite direction 2.5 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.
  5. If the front side (3) of the SIR coil does NOT have a centering window, and the back side (2) does NOT have a spring service lock (1), perform the following steps: Hold the coil with the face up. Rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub, slowly, counter clockwise, for 2.5 revolutions. This is center position. While maintaining the coil hub in center position, align the centered SIR coil with the horn tower and slide onto the steering shaft.

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, found on 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 shift, 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 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.
