B1900 srs code

[yakovenkooleg]

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?

TechStream definitely helps for being able to differentiate the sub codes. I worked on a rebuilt Tundra for a friend of mine, where he was having a pretensioner issue and it still remained opened as a 73 after he replaced the seatbelt. I scanned it with my Techstream and the code was a 1900. We found that the insulation on the pretensioner wires melted a bit (a couple of inches from the connector) and then with him moving the cable to unplug and replug the pretensioner the wires moved to where the exposed copper of the two wires was making contact.
