AIRBAG, SRS & ECU SERVICES

Airbag Reset & Car Module Programming Brisbane

Airbag light on after an accident? We clear the stored crash data from your original airbag (SRS) module, for all car makes. We also read and write SRS modules, reset battery modules, calibrate Toyota steering angle sensors and more. Send the make, model, year and the part number on the module and we confirm it is supported before any work starts.

OUR SERVICES

What we do

Seven services for airbag (SRS) modules, battery modules, steering angle sensors and control modules in newer and older cars. Tell us what the car or module is doing and we quote it first.

Airbag crash data reset

From $89all car makes · quoted before any work starts

After an airbag or seatbelt pretensioner fires, the SRS module records the crash and locks, and no scan tool can clear that record. We clear the crash data from your original module so it can work again.

  • Your original module is kept, so in most vehicles it goes back in without dealer coding
  • For airbag lights that stay on after an accident
  • Send the make, model, year and the part number on the module label

A reset does not replace airbags, seatbelt pretensioners or sensors that fired or were damaged.

SRS ECU read / write

We read the memory of an SRS (airbag) control module and write data back to it, for the modules on our supported list. Send the part number from the module label and we confirm it is supported before anything is done.

  • Modules on our supported list
  • Part number from the module label

Battery module reset (MVBM)

A battery module can be left with a locked fault after a collision, and some need a reset after the battery is replaced. We reset supported battery modules, including the MVBM.

  • Supported vehicles only
  • Make, model, year and module part number

Toyota SAS reset / calibration

Steering angle sensor (SAS) reset and calibration for supported Toyota sensors. A sensor that has lost its zero point can leave the stability control or steering warning lights on.

  • Toyota
  • Confirmed as supported before any work

ECM and other module resets

Some engine control module (ECM) and other module resets, depending on the ECU. Tell us the make, model, year and what the car is doing, and we tell you whether a reset can help or the module needs repair instead.

  • Depends on the ECU
  • Not a reset job? See ECU repair

Newer vehicles (CAN FD)

Newer vehicles use CAN FD, a faster version of the CAN network that connects the modules in the car. Our equipment speaks CAN FD built in, so a newer car is not left out.

  • CAN FD communication built in
  • Newer vehicles

Encrypted SRS modules (RH850 / V850)

Many newer airbag modules use an RH850 or V850 microcontroller with encrypted data. With an adapter we can process these modules, so a newer SRS module is not a dead end.

  • Newer SRS modules
  • Supported with an adapter

A reset does not repair damage

These services clear stored data, read or write a module's memory, or recalibrate a sensor. They do not repair physical damage. After a crash these still have to be replaced or repaired, and until they are the warning light stays on:

  • Airbags and seatbelt pretensioners that fired. An airbag is single-use.
  • Impact sensors and wiring damaged in the crash.
  • The clock spring behind the steering wheel, if the driver airbag fired or the wheel was disturbed.
  • A module that is crushed, burnt or water damaged: it should be replaced, not reset.

Some manufacturers specify a new module after any deployment, so for an insurance or dealer repair check what your repairer requires first.

How it works

Send the details, get a price first.

  1. 01Send the detailsThe make, model and year, the part number printed on the module label (or a photo of it) and what the car or module is doing.
  2. 02We confirm and quoteWe check the module or vehicle is supported and give you the price before any work starts.
  3. 03Bring it or post itBring the vehicle or just the module to our Seventeen Mile Rocks workshop (drop-off by arrangement), or post the module: postal repairs are accepted Australia-wide for eligible electronics.
  4. 04Service and checkThe service is done and the result is checked before the module goes back to you.

Common questions

Which cars do you work on?

Airbag crash data reset is for all car makes. The other services depend on the module or vehicle being on our supported list, so send the make, model, year and the part number printed on the module label and we confirm it first.

How much does it cost?

Airbag crash data reset starts from $89. Every other service is priced for your vehicle and module, and we confirm the price before any work starts.

Can I clear airbag crash data with an OBD scanner?

No. A scan tool can read and clear ordinary SRS fault codes, but crash data is stored as a permanent record that scan tools are not allowed to erase. The code comes straight back. The record has to be cleared from the module's memory, which is what an airbag crash data reset does.

Is it safe to drive with the airbag light on?

Treat it as unsafe. When the SRS light stays on, the system has found a fault and the airbags and seatbelt pretensioners may not work in a crash. Have the fault read and fixed before relying on the car.

Will a reset fix a damaged airbag system?

No. A reset clears stored data or recalibrates a module. Airbags and seatbelt pretensioners that fired, damaged sensors or wiring, and a module that is crushed, burnt or water damaged still have to be replaced or repaired, and until they are the warning light stays on.

Do I need to bring the whole car?

Often only the module is needed. Drop-off is by arrangement at our Seventeen Mile Rocks workshop, and we accept postal repairs Australia-wide for eligible electronics. Contact us first so we can confirm it is suitable.

What if my module is not on the supported list?

Tell us anyway. If a reset is not possible we say so before any work starts, and if the module has failed we can tell you whether board-level repair is an option.

Not sure which service you need?

Send us the make, model, year and what the car is doing. CQ Electronics confirms what can be done and quotes it before any work starts.
