B1900 srs code - Toyota Yaris Forums

the thing is tho..code 73 comes up for all for DTC codes ( B1900, B1901, B1902 and B1903) so if its an open circuit or a shorting in the circuit it will still be code 73 until u scan it with a scanner and pull out actual B code. at first when i fixed the car< i didn't know that the belt went off so i just replaced the drivers bag and went to the dealer to get the light shut off.. he told me that there is a cod B1901/73, which is a open in a circuit, so then i replaced the belt, the B1901 was cleared but B1900 is now appearing. i am just wondering back when i had the B1901 code, why did the computer showed only this code, but didnt show the B1900?
