1994-96 Avenger, Sebring, Eclipse, Galant & Talon Airbag Module: Fixing the SRS Light and Crash Data Issues

Symptoms of a Failing Air Bag Control Module

The signs of a faulty airbag module are usually very clear, but it's important to distinguish them from other issues in the SRS system.

• Airbag/SRS Warning Light: The most common and immediate symptom is the airbag warning light (often showing an icon of a person with an airbag, or the letters "SRS") staying illuminated on your dashboard after the initial startup check. This indicates a fault has been detected, and the entire airbag system is disabled as a safety precaution.
• Failure to Deploy: In a collision, the most serious symptom is the failure of the airbags to deploy. This indicates a complete failure of the module or another critical system component.
• Intermittent Electrical Issues: In rare cases, a failing module can cause other strange electrical problems, like random warning lights or battery drain, due to internal short circuits.
• Diagnostic Trouble Codes (DTCs): A professional scan tool can read specific codes from the module. For these 1994-1996 vehicles, you may need more than a basic code reader. Codes indicating an "internal fault" or "crash data stored" point directly to a problem with the module itself. On some older systems, the airbag light may flash a sequence of blinks to indicate a specific fault code.

Known Issues, Recalls, and Technical Bulletins

While there are no widespread, major recalls specifically for the airbag control module on these exact 1994-1996 models, some related issues and common problems for electronics of this era are worth noting.

• No Specific Recalls: Searches for recalls on the 1995-1996 Dodge Avenger, 1995-1996 Chrysler Sebring Coupe, 1995 Mitsubishi Eclipse, 1994-1996 Mitsubishi Galant, and 1995 Eagle Talon do not show any specific campaigns for replacing the airbag control module. Later model year Avengers and Sebrings were involved in large airbag recalls, but these do not apply to the mid-90s generation.
• Water Intrusion: A common failure point for airbag modules in many vehicles of this period is water damage. The module is typically located on the floor, on the central transmission tunnel under the center console. Spilled drinks or a water leak from a bad seal can allow moisture to reach the module, causing corrosion on the circuit board and leading to failure.
• Capacitor Failure: Like much of the electronics from the 1990s, these modules can be susceptible to aging capacitors. When capacitors fail, they can leak, lose their ability to hold a charge, and cause the module to malfunction, triggering the SRS light.

The Critical Role of "Crash Data"

Understanding crash data is the single most important concept when dealing with this part. After a vehicle is in an accident, the airbag module permanently stores data about the event, even if the airbags did not deploy. This is often referred to as a "hard code" or "crash event."

• System Lockout: Once crash data is stored, the module locks itself and disables the airbag system. This is a safety feature to ensure the entire system is inspected and repaired after an incident.
• Cannot Be Cleared by Scanners: This stored crash data cannot be cleared with a standard OBD-II scanner or by disconnecting the battery. It requires specialized equipment to access the module's internal memory (EEPROM) and wipe the data.
• Used Parts Concern: A used module pulled from a vehicle that was in an accident will have this crash data stored. Installing it in your car will not solve your problem; the airbag light will remain on, and the system will stay disabled.

Buying a Used Air Bag Control Module

A used OEM module is an excellent, cost-effective choice, as new aftermarket or OEM parts are generally unavailable for vehicles of this age. However, you must be an informed buyer.

1. Verify the Part Number: Match the part number on your original module exactly. The most common part numbers for this group of vehicles are Mitsubishi numbers like MB942682, MR243890, or X006T37173.
2. Ask About Crash Data: This is the most important question. Only buy a module that is guaranteed to be from a non-wrecked vehicle with no airbag deployment, or one that has been professionally reset. A module with stored crash data is just a paperweight until it is sent to a reset service.
3. Inspect for Damage: Check the casing for any cracks or signs of being dropped. Look closely at the connector pins for any corrosion (green or white powder), which indicates past water damage. Do not buy a module with any signs of corrosion.
4. Plan for a Reset: The safest and most reliable approach is to buy a used module with a matching part number and send it to a professional SRS module reset service before installation. These services are affordable (typically under $100) and ensure the module is clear of any old fault codes or hidden crash data.

Programming and Installation Requirements

For these mid-1990s vehicles, the primary concern is not complex programming but ensuring the module is clear of data.

• No VIN Programming Required: Unlike modern vehicles, this airbag module is not typically programmed or "locked" to the vehicle's VIN. You can install a used module from another vehicle without needing a dealer to program it.
• Crash Data Reset is Key: The module MUST be free of stored crash data to function. You can either buy a module that has already been reset or send your original/used module to a reset service. After a reset service, the module is plug-and-play.
• Fault Code Clearing: After installing a clean, reset module and ensuring all other SRS components (sensors, clockspring, airbags) are properly connected, you may still need to clear any "soft" fault codes from the system using a compatible SRS diagnostic scanner. In some cases, simply disconnecting the battery during the install is sufficient.

Replacement Overview

Replacing the airbag module is straightforward for a DIY mechanic with basic tools. The module is typically located in the center of the vehicle, bolted to the floor under the center console or forward dash area.

1. DISCONNECT THE BATTERY. This is the most critical safety step. Disconnect the negative battery terminal and wait at least 15-20 minutes for the system's backup power capacitors to fully discharge. Failure to do so could result in accidental airbag deployment.
2. Access the Module: You will likely need to remove the center console trim pieces to get to the module.
3. Unplug and Unbolt: Carefully disconnect the electrical connectors. They often have security tabs that need to be pressed or slid. Then, remove the bolts (usually 3 or 4) holding the module bracket to the vehicle's floor tunnel.
4. Install the New Module: Bolt the replacement (and reset) module into place. Ensure the arrow on the module is pointing toward the front of the vehicle. Reconnect the electrical plugs securely.
5. Reassemble and Reconnect: Reinstall the console trim, and only then, reconnect the negative battery terminal.
6. Verify Operation: Turn the ignition to the 'ON' position. The SRS light should illuminate for a few seconds and then turn off. If it stays on, a fault is still present in the system that needs to be diagnosed with a scanner.

Cost Comparison

Replacing the airbag module can have a wide range of costs depending on the path you choose. Given the age of these vehicles, new parts are generally not an option.
