I bought my car at an auction when it was hit in the left side. i changed all the blow airbags and the airbag module. but the airbag light is still on! now i dont know what to do. can somebody tell me what to do? did you have the same problem? i know that toyotas have the same parts as the lexus. so please help if you worked on a toyota too. do i need to change any sensors. and i need a diagram of the car if anybody has it thanks.

You need to find out what the trouble codes are causing the light to be on to narrow down the problem. Did you replace the seatbelt assy?:

genka1225

yes i did change the seat belt. because it was blown too. now all my seatbelts work fine and all the airbags are changed. but the light is still on. i went to the shop and they hooked up a computer to my car and it didnt show any codes. so i dont know whats wrong. please help

They need to access the SRS system with their scanner. If the light is on, there are codes.

genka1225

it said that its a terminal circuit malfunction. but i dont know what that has to do with the airbags.

Follow this procedure, and let us know what codes you pull. Just use a wire as the (SST Check Wire)


DTC CHECK/CLEAR

SUPPLEMENTAL RESTRAINT SYSTEM DTC CHECK (USING SST CHECK WIRE)





Check the DTCs (Present trouble code).
Turn the ignition switch to the ON position, and wait for approximately 60 seconds .
Using SST, connect terminals TC and CG of the DLC3. SST 09843-18040 NOTE: Connect the terminals to the correct positions to avoid a malfunction.
Check the DTCs (Past trouble code).
Using SST, connect terminals TC and CG of the DLC3. SST 09843-18040 NOTE: Connect the terminals to the correct positions to avoid a malfunction.
Turn the ignition switch to the ON position, and wait for approximately 60 seconds .
Read the DTCs.



Read the blinking patterns of the DTCs. Examples, the blinking patterns for normal system code and trouble codes 11 and 31 are shown in the illustration.
Normal system code indication (w/o past trouble code) The light blinks twice per second.
Normal system code indication (w/ past trouble code) When the past trouble code is stored in the airbag sensor assembly center, the light blinks only once per second.
Trouble code indication The first blinking indicates the first DTC. The second blinking occurs after a 1.5-second pause. If there are more than 1 code, there will be a 2.5-second pause between each code. After all codes are shown, there will be a 4.0-second pause, and they all will be repeated.
HINT:


If 2 or more malfunctions are found, the indication begins with the smaller numbered code.
If DTCs are indicated without connecting the terminals, proceed to the "TC Terminal Circuit
