Alfa Romeo Airbag Module Reset

How to fix an airbag light for an Alfa Romeo.

If the Alfa_Romeo has been in an accident and airbags and/or seatbelts have deployed, ‘permanent’ crash data will be stored on the module.   We can restore the module to its pre-crashed state with an Alfa Romeo airbag module reset.

If the Alfa Romeo has not been in an accident, but the airbag light does not switch off or the airbag light flashes, the SRS system should be scanned to find the source of the problem.  If, after diagnosis, the problem is believed to be in the module, we can often repair the module.

When you receive your airbag module back after it has been reset or repaired by Raceevo, it will plug and play as the original configuration will be maintained.

How to remove an airbag module from an Alfa Romeo.

The airbag module can usually be found under the centre console or under a front seat.  Before working on the airbag module, disconnect the battery and wait at least 2 minutes.  Not disconnecting the battery before unbolting or disconnecting the cable to the module risks deployment of airbags and seatbelts and also introducing additional faults on the module.

How to fit an airbag module to an Alfa Romeo.

Before working on the airbag module, disconnect the battery and wait at least 2 minutes.  Once the airbag module has been bolted down and the cable connected, the battery can be reconnected.  It is best practice to switch on the ignition from outside the car when testing the system.  When turning on the ignition, the airbag light will illuminate for a few seconds while the module powers up and checks the system.  If all is well, the light will go off and stay off.

For modules not listed, it is likely that we can reset these too. Just text a photo of the label to 0419 158 998 or email paul@raceevo.com.au for a quick reply on doability and price.

Some Alfa Romeo models will illuminate the airbag light following a flat battery.
A common problem is the vehicle develops an electrical drain and eventually the battery is discharged.
The airbag problem occurs when you try to crank the engine when the battery is low or you boost start the car either with jump leads but mainly when a boost pack is used. This creates a voltage spike in the airbag module and corrupts the programming data contained within it. In many cases when you connect a diagnostic computer to try to clear the airbag fault codes, the airbag module will not communicate with the computer or it reads a 'defective ecu' fault code which will not clear. The battery drain is normally caused by a bad earth and it commonly affects the 147 & 156 models. The bad earth causes the rev counter 'bulb check circuit' to fail & you will find you have a rear light constantly glowing dimly. Over time this drains the battery and then when you boost start the car it spikes the airbag module and locks it out.
To repair this fault you have to locate and repair the bad earth - This is usually the main battery earth lead & poor earths to the engine & gearbox. To be sure you should check & clean all earth points, so battery, engine, gearbox, chassis legs & rear lamps.
- Replace any earth leads that are corroded or broken
- Replace any blown bulbs
- Recharge the battery
- Remove the airbag module and send it to us for repair
