What pin do you cross to reset the air bag light

B1941 41 RH primary crash sensor feed/return circuit open GO to DTC B1941.
DTC B1941: RH PRIMARY CRASH SENSOR FEED/RETURN CIRCUIT OPEN- LAMP FAULT CODE 41

Normal Operation
The voltage at Pin C276-16, Circuit 617 (PK/O) is set by the air bag diagnostic monitor to be slightly less than battery voltage. Circuit 617 (PK/O) is connected to Circuit 624 (Y/W) inside RH primary crash sensor. Therefore, the voltage at Circuit 624 (Y/W) and air bag diagnostic monitor Pin C277-24 should be the same as the voltage at air bag diagnostic monitor Pin C276-16, Circuit 617 (PK/O).
The air bag diagnostic monitor periodically pulls the voltage at Pin C276-16, Circuit 617 (PK/O) low to verify the connection to Pin C277-24, Circuit 624 (Y/W). If the voltage at Pin C277-24, Circuit 624 (Y/W) does not pull low as a result of this test, the air bag diagnostic monitor will store in memory DTC B1941 and flash lamp fault code 41 on the AIR BAG indicator. If the connection between Pins C276-16, Circuit 617 (PK/O) and C277-24, Circuit 624 (Y/W) is later serviced, DTC B1941 will be stored in memory.
Possible Causes
Failure to get low voltage at Pin C277-24, Circuit 624 (Y/W) during the test can be caused by:

• an open circuit in the wiring harness in either Circuit 617 (PK/O) or Circuit 624 (Y/W).
• an open circuit inside RH primary crash sensor across Circuit 617 (PK/O) or Circuit 624 (Y/W).
• a short to battery or ignition voltage in any of the Circuits 617 (PK/O), 619 (PK/W), 624 (Y/W), 625 (Y/LG).

Young boys will do that.lol. crossed a wire somewhere.

Chances are it's the airbag clockspring mechanism behind the horn in the steering wheel, they wear out and cause the light to flash. There is no reset for the light. If it's on, you have a short or a bad connection. The clockspring is available at most auto parts stores and installs with a few screws. Make sure you disconnect the battery before you do anything related to the airbag because you don't want it to go off while you are working on it.

First correct the problem before any resetting is done.need to repair the wire (check wire color).disconnect one battery terminal first before anything else.If wire is broken form the connector pin using pointed stiff wire pry off the pin lock up(plastic lock ussually diff color from the connector)pull it off completely and from inside the connector u can see a tiny lock each and every pins.use the pointed wire lift slightly the lock and pull or push the pin out.use solder to join the pin and wire.you may need a diagnostic computer to reset the mil light (malfunction indicator light)

Pinpoint Test R: Diagnostic Trouble Code 44 — RH Radiator Primary Crash Front Air Bag Sensor Not Mounted to Vehicle Properly Normal Operation
NOTE: Circuit 618 (BL/W) is grounded to the side of the RH radiator primary crash front air bag sensor case, and the case is grounded through the bracket to the vehicle at its mounting point.
The air bag diagnostic monitor (14B056) measures the resistance between pin 20 (circuit 618 [BL/W]) and pin 3 (circuit 57M [BK]), the air bag diagnostic monitor reference ground. If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between pin 20 and pin 3, it will flash diagnostic trouble code (DTC) 44.
Possible Causes
High resistance on pin 20 (circuit 618 [BL/W]) to ground can be caused by:

• A poor connection due to loose mounting, dirt, or corrosion at the RH radiator primary crash front air bag sensor bracket mounting location.
• An open or damaged wire in circuit 618 (BL/W) from pin 20 of the air bag diagnostic monitor connector to the RH radiator primary crash front air bag sensor connector.
• An open circuit inside the RH radiator primary crash front air bag sensor.

take it to another dealer, in most cases its just a poor connection, poor contact in one of the pin connectors, air bag wiring is very sensative,one poor pin connection does not allways mean that the harness needs to be replaced, it sounds like they dont want to take the time to pinpoint the problem.

If the air bag light is on there is a problem with the air bag. The light means the air bags will not deploy in an accident. Only a qualified tech should work on air bags.

Possible trouble areas are drivers side air bag, spiral cable in column, wiring to the air bag sensor assembly or the sensor assembly its self. Without a competent technician using the proper diag tools it would hard to pin point the problem.

CLEARING CODES (works for code 52)
1. Only intermittent codes and codes that diagnostic monitor recognizes as being repaired may be cleared from memory. To clear codes, cycle ignition OFF to ON. Observe AIR BAG warning light. AIR BAG warning light will illuminate for 4-8 seconds, and flash fault code.

(Comment) Loosely translated - If you dont have the problem fixed, this wont work. Code 52 should clear with this!

2. Locate air bag diagnostic 2-pin connector.

(Comment) This was a fun one. According to the air bag wiring diagram that I also got from Mitchell, the Airbag Diagnostic Connector is located "Right side of Instrument Panel". The only thing I found immediately to the right of the I/P (between the stereo and Instrument panel) was a black computer with 4 connectors which is NOT what I was looking for. I finally found a blog that mentioned the computer for the air bag computer was behind the right side kick panel. Sure enough....there it was. Attached to the side of the diagnostic computer was a two prong diagnostic connector.

3. Connect a jumper wire between diagnostic connector terminals. Leave jumper wire connected until diagnostic monitor tone sounds (about 5 seconds). Disconnect jumper wire. Fault code is cleared.
