Module, Steering Column Control (SCCM): Installation

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to follow these instructions may result in accidental airbag deployment.

  1. Align the notch (4) in the collar on the back of the Steering Column Control Module (SCCM) unit (1) to the alignment tab at the 12 o'clock position on the top of the steering column housing (5).
  2. Using both hands, press the SCCM downward over the top of the steering column firmly and evenly until the latch feature of the collar snaps into place over the retention tab (3) at about the 1 o'clock position on the top of the steering column housing. The retention tab must be fully within the opening of the collar clamp (2) as shown in the illustration above.
    NOTE:

    The SCCM housing must be held firmly while tightening the band clamp screw to keep it from rotating clockwise on the column housing.

  3. Install the band clamp fasteners that secures the collar of the SCCM unit to the steering column. The fasteners is installed from the underside of the steering column. Tighten the fasteners to the proper torque specifications. Refer to TORQUE SPECIFICATIONS  .
  4. Connect the instrument panel wire harness connectors to the back of the SCCM housing.
  5. Install the upper and lower shrouds onto the steering column. Refer to SHROUD, STEERING COLUMN, UPPER, INSTALLATION .
  6. Move the steering column back to the fully raised position and move the tilt release lever back to the locked (up) position.
  7. If a new SCCM is being installed, remove (break off) the yellow locking tab that secures the clockspring rotor to the clockspring case.
  8. Install the steering wheel to the steering column. Be certain to align and insert the rotational lugs on the steering wheel hub into the slots in the hub of the clockspring. Also, the steering wheel fastener MUST  be tightened to the proper torque specification to ensure proper clockspring operation. Refer to WHEEL, STEERING, INSTALLATION .
  9. Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
NOTE:

If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to determine if alignment of the PROXI configuration data into the new ECU is needed. If PROXI alignment is needed, follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under the Body Control Module (BCM) Miscellaneous Functions menu.
