Service Precautions

1990 Dodge and Ram Shadow ES, 2D Hatchback, 2.2 CSECTION Service Precautions
NOTE: These precautions should be observed when working with air bag systems:
  • Disable air bag system before servicing any air bag system or steering column component. Failure to do this could result in accidental air bag deployment and possible personal injury. See DISABLING & ACTIVATING AIR BAG SYSTEM  .
  • After repairs, turn ignition on from passenger side of vehicle in case of accidental air bag deployment. Ensure AIR BAG light is working properly and no system faults are indicated. See TESTING - SYSTEM OPERATION CHECK  .
  • Always wear safety glasses when servicing or handling an air bag.
  • Air bag module must be stored in its original special container until used for service. It must be stored in a clean, dry place, away from sources of extreme heat, sparks and high electrical energy.
  • When placing a live air bag on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of module if accidentally deployed.
  • After air bag deploys, surface may contain deposits of sodium hydroxide, which irritates skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up, and wash hands using mild soap and water. Follow correct disposal procedures. See DISPOSAL PROCEDURES  .
  • Because of critical system operating requirements, DO NOT  attempt to service any air bag components. Corrections are only made by replacing defective part.
  • Electrical sources should NEVER be allowed near inflator on back of air bag module.
  • When carrying a live air bag module, trim cover should be pointed away from body to minimize injury in case of accidental deployment.
  • When testing voltage or continuity at Air Bag System Diagnostic Module (ASDM), use terminal side (not the wire end) of connector.
  • DO NOT  probe a wire through insulator; this will damage it and eventually cause failure due to corrosion.
  • Clockspring must be replaced whenever air bag deploys.
  • When performing electrical tests, prevent accidental shorting of terminals. Such shorts can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult.
  • When using diagnostic charts to diagnose air bag system, use DRB-II volt-ohmmeter unless otherwise instructed to use an external volt-ohmmeter. NEVER use an analog volt-ohmmeter or test light in place of a digital volt-ohmmeter.
  • If air bag system is not fully functional for any reason, vehicle should not be driven until system is repaired and again becomes operational. DO NOT  remove bulbs, modules, sensors, or other components or in any way disable system from operating normally. If air bag system is not functional, park vehicle until it is repaired and functions properly.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
