What we do with module 89170-47721
Crash data reset
We erase the crash record so the module works again after the deployed airbags and pretensioners have been replaced.
Reading and clearing fault codes
We read the SRS module codes (B-codes), check which are active and clear them after the repair.
FLASH read and write
Work with the module firmware – for recovery or transfer to another module with the same part number.
Module identification
We read the part number, software version and VIN so we are sure we work with the right record.
How it works for Toyota with this module
- You order through the form or by phone. You receive the address and packing instructions.
- You remove the module after disconnecting the battery and waiting 10 minutes.
- You send it by tracked courier from anywhere in the EU. We also accept an enquiry with a photo of the label.
- We connect it on the bench – we read the internal memory of the microcontroller and make a full backup before any work. We clear the crash data and the fault codes.
- We ship it back by tracked courier the same or the next working day. On refitting, check the other control units for a stored crash.
When it is needed
- After a crash with deployed airbags or pretensioners – the module keeps the record and will not re-arm the system.
- After a lighter impact where only the belt pretensioners fired – the light stays on although the airbags are intact.
- With a used module from another vehicle that has a stored crash.
- With an imported car that arrives with an airbag light and a crash record in its history.
What a reset does NOT fix
- A damaged airbag, pretensioner or crash sensor – they set a new fault immediately.
- A broken wire or corroded connector under the seat – the most common reason for the light without a crash.
- A module with a burnt board after a short circuit – for Toyota we then source a module with the same part number and clone it.
Frequently asked questions
Do I have to remove module 89170-47721?
Yes. This module is handled only on the bench – it is connected directly to the board. Send it by tracked courier; we ship it back the same or the next working day. Disconnect the battery and wait a few minutes before removal.
Why is the airbag light still on after the reset?
Because crash data is not the only cause. If an airbag, pretensioner, crash sensor or connector is damaged or has not been replaced, the module logs a new fault. That is why we read all fault codes before the reset and tell you what still needs replacing.
Can you clear the crash data without replacing the airbags?
We do not. The module stores the record because the components have fired. We reset it only once the airbags and pretensioners have been replaced; otherwise the system will not protect the occupants in the next crash.
How much does the reset of module 89170-47721 cost?
The price depends on the method (OBD or bench) and whether there are other faults. We confirm it by phone from the part number before we start. No hidden costs – if the module is faulty and cannot be recovered, you do not pay for the attempt.
