What do airbag flash codes 22, and 18 mean on a 2003 Toyota corolla?

The SRS (Supplemental Restraint System) light turning on in your 2003 Toyota Matrix indicates that there may be a problem with the airbag system. It is important to have this issue addressed as soon as possible, as the airbags may not deploy properly in the event of an accident.

There are a few different things that could cause the SRS light to turn on. Here are a few things you can try:

Check the connections to the SRS system. Make sure all of the connectors are securely attached and that there are no loose or damaged wires.

Check the SRS control module. If the control module is faulty, it could cause the SRS light to turn on.

Check the airbag sensors. If any of the airbag sensors are faulty, it could cause the SRS light to turn on.

When the SRS warning light comes on the system's control module has detected a fault, more than likely you have a fault code in the module you need read to see what is causing this, when the light is on the SRS is disabled. no airbags will deploy.

air bags
get the bags scanned,
read the FSM on bags yet< (factory service manual)
or at alldata.com, DIY.
in what country? , did you read the TSB recall yet>?????
huge recall.
where is this 31 code? at>?
Trouble Code: B1000/31 (1.8L L4 VIN R Auto)
Airbag ECU Malfunction * Airbag sensor assy center

remove battery neg lug before touching any SRS parts.
B1000/31; Center Airbag Sensor Assembly Malfunction (2006 Corolla From 07/2005) DESCRIPTION The center airbag sensor assembly consists of a deceleration sensor, safing sensor, drive circuit, diagnosis circuit, ignition control, etc.
If the center airbag sensor assembly receives signals from the deceleration sensor, it determines whether or not the SRS should be activated.
DTC B1000/31 is recorded when a malfunction is detected in the center airbag sensor assembly.

If only DTC B1000/31 is output, do not clear the DTCs, replace the center airbag sensor assembly.
If any DTCs other than DTC B1000/31 are also output, troubleshoot those DTCs first.


use a real scan tool
and see all errors.
if not you guess wrong.

It is always better to start with retrieving the SRS error codes and strictly following the instructions and cautions provided by the manufacturer before you could repair the air bag issues.
Or pull up the SRS error codes and post them here so that we can guide you how to do it.
The error codes can be retrieved manually and as well as with the help of a diagnostic computer.

You will need to scan the codes for the air bag system to find out what is wrong, when the problem is repaired the system runs a test every time the engine is started and with repair done light will go off,

Try taking the efi relay out for about a min and than reinstalling,or just remove batteries out and reinstall.
Computer might need resetting by a Tech head with proper diagnostic tool

SRS SYSTEM HAS A FAULT , THIS COULD MEAN MANY THING
INPORANT TO KNOW SRS DOES A SELF CHECK EVERYTIME YOU START YOU VEHICLE , THIS LETS YOU KNOW IF THE SYSTEM IS WORKING OR NOT.

IT LOOKS AS IF YOU HAVE A FAULT WITH A PART OF THE SRS CIRCUIT.
PLEASE DO NOT TRY TO FIX , COULD BE DANGEROUS!!!
YOU NEED TO TAKE IT TO YOUR LOCAL DEALER.
THEY WILL SCAN SYSTEM.
AFTERMARKET GARAGES DONT HAVE AXCESS TO THE SRS SYSTEM.
THERE COULD BE A SHORT OR OPEN IN CIRCUIT.
I HOPE THIS HELPS

You need either the dealer scantool or a third party SRS scantool capable of OCS (occupant classification system) calibration.

Neither is cost effective to buy for personal use, as the prices are in the thousands for either.

OCS calibration is usually a half hour labor charge at most, typically in the $45 range at most shops.
