Chrysler Neon 1995-1999 Repair Guide

General Information


See Figures 1 and 2

The Supplemental Restraint System (SRS), found on all vehicles covered by this guide, is designed to be used along with the front seat belts to reduce the risk or amount of injury by deploying one or both air bags during certain frontal collisions.

The air bag system is made up of left and right front impact sensors, air bag modules for the driver (in the steering wheel) and front passenger (right side instrument panel above the glove compartment), SRS diagnosis unit (with a safing sensor) and a SRS warning lamp in the instrument cluster.

The SRS system is designed to deploy when the safing sensor, along with either or both of the impact sensors simultaneously activate while the ignition is ON . The sensors will activate during front or near-frontal impacts of moderate to severe force.


When working on the SRS or any components which require the removal of the air bag, adhere to all of these precautions to minimize the risks of personal injury or component damage:

Before attempting to diagnose, remove or install the air bag system components, you must first detach and isolate the negative (-) battery cable. Failure to do so could result in accidental deployment and possible personal injury.
When an undeployed air bag assembly is to be removed from the steering wheel, after detaching the negative battery cable, allow the system capacitor to discharge for two minutes before commencing with the air bag system component removal.
Replace the air bag system components only with Mopar® specified replacement parts, or equivalent. Substitute parts may visually appear interchangeable, but internal differences may result in inferior occupant protection.
The fasteners, screws, and bolts originally used for the SRS have special coatings and are specifically designed for the SRS. They must never be replaced with any substitutes. Anytime a new fastener is needed, replace with the correct fasteners provided in the service package or fasteners listed in the parts information.

Handling A Live Air Bag Module

At no time should any source of electricity be permitted near the inflator on the back of the module. When carrying a live module, the trim cover should be pointed away from the body to minimize injury in the event of accidental deployment. In addition, if the module is placed on a bench or other surface, the plastic trim cover should be face up to minimize movement in case of accidental deployment.

When handling a steering column with an air bag module attached, never place the column on the floor or other surface with the steering wheel or module face down.

Handling A Deployed Air Bag Module

The vehicle interior may contain a very small amount of sodium hydroxide powder, a by-product of air bag deployment. Since this powder can irritate the skin, eyes, nose or throat, be sure to wear safety glasses, rubber gloves and long sleeves during cleanup.

If you find that the cleanup is irritating your skin, run cool water over the affected area. Also, if you experience nasal or throat irritation, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician.

Begin the cleanup by putting tape over the two air bag exhaust vents so that no additional powder will find its way into the vehicle interior. Then remove the air bag and air bag module from the vehicle.

Use a vacuum cleaner to remove any residual powder from the vehicle interior. Work from the outside in so that you avoid kneeling or sitting in an uncleaned area.

Be sure to vacuum the heater and A/C outlets as well. In fact it's a good idea to run the blower on low and to vacuum up any powder expelled from the plenum. You may need to vacuum the interior of the car a second time to recover all of the powder.

Check with the local authorities before disposing of the deployed bag and module in your trash.

After an air bag has been deployed, the air bag module and clockspring must be replaced because they cannot be reused. Other air bag system components should be replaced with new ones if damaged.


To disarm the SRS, simply detach the negative battery cable from the battery. Isolate the battery cable by taping up any exposed metal areas of the cable. This will keep the cable from inadvertently contacting the battery and causing accidental deployment of the air bag. Allow the system capacitor to discharge for at least 2 minutes, although 10 minutes is recommended to allow the dissipation of any residual energy.


After finishing the service procedures, you must perform the following procedure:

  1. Connect a DRB or equivalent scan tool to the Data Link Connector (DLC), located at the right side of the steering column and at the lower edge of the lower instrument panel.
  3. Turn the ignition key to the ON position. Get out of the vehicle with the scan tool. Make sure you are using the latest version of the proper cartridge.
  5. After making sure no one is in the vehicle, remove the tape, then reconnect the negative battery cable.
  7. Read and record any stored Diagnostic Trouble Codes (DTCs). If any diagnostic trouble codes are recorded, take your vehicle to a reputable repair shop for diagnosis.
  9. If there are no DTCs, and if the airbag warning lamp either fails to light, with the ignition switch ON , or the light goes on and stays on, there is a system malfunction. If any of these conditions exist, you should take your vehicle to a reputable repair shop for diagnosis.
