TROUBLE SHOOTING

Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.

SERVICE PRECAUTIONS

Observe the following precautions when servicing air bag system

  1. Disable air bag system before attempting any repairs to steering column or components. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__disabling-activating-air-bag-system) .
  2. After disabling air bag system, DERM maintains back-up voltage. To avoid accidental deployment, wait at least 15 minutes after disabling air bag system before servicing.
  3. Always wear safety glasses when servicing system.
  4. Always carry a live (undeployed) air bag with trim cover facing away from your body. This minimizes chance of injury if air bag accidentally deploys.
  5. Place a live (undeployed) air bag on a bench or other surface with trim cover facing up, away from surface. This will reduce motion of air bag if it accidentally deploys.
  6. Never probe inflator module connectors; air bag may accidentally deploy.

DISABLING & ACTIVATING AIR BAG SYSTEM

CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery.
  1. Before proceeding, follow air bag service precautions. See «SERVICE PRECAUTIONS»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__service-precautions) . To disable air bag, turn ignition off. Disconnect and shield negative battery cable. Remove SIR fuse from fuse block. Remove Connector Position Assurance (CPA) clip from Yellow SIR connector at base of steering column. (All SIR system connectors use CPA clips to ensure connector retention.) Disconnect Yellow connector. Wait 15 minutes before working on vehicle.
  2. To activate air bag system, turn ignition switch off. Connect Yellow SIR connector and CPA clip at base of steering column. Install SIR fuse. Connect negative battery cable. Turn ignition switch to RUN position. Observe AIR BAG indicator light. Light should flash 7-9 times, and then go out. If AIR BAG indicator light does not function as described, a malfunction in air bag system exists.

REMOVAL & INSTALLATION

CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery.

Removal

Before proceeding, follow air bag service precautions. See SERVICE PRECAUTIONS . Disable SIR system. See DISABLING & ACTIVATING AIR BAG SYSTEM . Remove and discard 4 air bag module screws behind steering wheel. Pull up air bag module, and then disconnect electrical connectors from module. Remove module. Installation

Connect electrical connectors to module. Install module using 4 new mounting screws. Tighten screws to 106 INCH lbs. (12 N.m). Activate SIR system. See DISABLING & ACTIVATING AIR BAG SYSTEM .

Removal (With SIR)

  1. Set front wheels in straight-ahead position. Turn ignition switch to LOCK position. Before proceeding, follow air bag service precautions. See «SERVICE PRECAUTIONS»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__service-precautions). Disable SIR system. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__disabling-activating-air-bag-system).
  2. Remove and discard 4 air bag module screws behind steering wheel. Pull up air bag module, and then disconnect electrical connectors from module. Remove module. Disconnect cruise control switch connector (if equipped) and horn switch connector.
  3. Mark steering wheel hub in relation to steering shaft for installation reference. Remove steering wheel nut. Using Steering Wheel Puller (J-1859-03), remove steering wheel. DO NOT install puller bolts too deeply into hub, as SIR coil assembly can be damaged. (Scheme 1) To prevent coil assembly from rotating, insert Yellow tab (if available) into coil assembly, or tape coil assembly in place.

Installation

Remove Yellow tab or tape from coil assembly. Install steering wheel, aligning marks on steering wheel hub and steering shaft. Tighten steering wheel nut to 30 ft. lbs. (41 N.m). To install remaining components, reverse removal procedure. Activate SIR system. See DISABLING & ACTIVATING AIR BAG SYSTEM .

Removal & Installation (Without SIR)

  1. Set front wheels in straight-ahead position. Turn ignition switch to LOCK position. Pull up horn pad, and then disconnect cruise control switch connector (if equipped) and horn switch connector. 2) Mark steering wheel hub in relation to steering shaft for installation reference. Remove steering wheel nut. Using Steering Wheel Puller (J-1859-03), remove steering wheel. 3) To install, align marks on steering wheel hub and steering shaft, and then install steering wheel. Tighten steering wheel nut to 30 ft. lbs. (41 N.m). To install remaining components, reverse removal procedure.

SIR COIL ASSEMBLY

CAUTIONTo center coil assembly, set front wheels in straight-ahead position before removing or installing coil assembly. If an uncentered coil assembly is installed, ribbon in coil assembly will break when steering wheel is turned. Always keep ignition switch in LOCK position to prevent wheel from turning and uncentering coil assembly.
  1. Set front wheels in straight-ahead position and turn ignition switch to LOCK position. Before proceeding, follow air bag service precautions. See «SERVICE PRECAUTIONS»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__service-precautions). Disable SIR system. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__disabling-activating-air-bag-system). Remove air bag module and steering wheel. See «AIR BAG (INFLATOR) MODULE»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column) and «STEERING WHEEL»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column).
  2. Remove upper and lower steering column shrouds. (Scheme 1) Disconnect SIR coil assembly electrical connector. To prevent coil assembly from rotating, insert Yellow tab (if available) into coil assembly, or tape coil assembly in place. Remove coil assembly.
  3. To install, reverse removal procedure. Remove Yellow tab or tape from coil assembly after installing steering wheel. Activate SIR system. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/saturn/sl/i-1990-1995/remont/steering-column/#steering-column__disabling-activating-air-bag-system).
