DTC B0058 Right Front/Passenger Pretensioner Deployment Loop Open.
The passenger seat belt pretensioner deployment loop consists of a seat belt pretensioner-RF and the seat belt pretensioner-RF high and low circuits. A shorting bar used within the seat belt pretensioner connector shorts together both the seat belt pretensioner high and low circuits when the connector is disconnected. This will help to prevent unwanted deployment of the pretensioner during servicing. During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the seat belt pretensioner. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a diagnostic trouble code (DTC) will be stored in memory.
DTC B0084 Left Front/Driver Seat Position Sensor Circuit
The inflatable restraint seat position sensor (SPS) is used to determine the proximity of a front driver or passenger seat position with respect to the frontal air bag. The SPS interfaces with the sensing and diagnostic module (SDM). The state of the SPS allows the SDM to disable stage 2 of the frontal air bag for a front seat that is forward of a forward/rearward point in seat track travel. The SPS is a hall effect sensor that is mounted on the inside seat track of both the driver and passenger seats. The seat track includes a metal bracket that shunts the SPS magnetic circuit creating 2 states of seat position. The shunted state represents a rearward seat position. The non-shunted state represents a forward position. The SPS provides 2 current ranges, one range for the shunted state and a second range for a non-shunted state. These 2 states are inputs to the SDM. State 1 (shunted) being the rearward threshold and state 2 (non-shunted) being the forward threshold. When the SDM receives input from a SPS that state 1 threshold is reached (seat is rearward) the SDM will not disable stage 2 deployment, if required by the deployment sensors. When state 2 threshold is reached (seat is forward) the SDM will disable stage 2 deployment on the side the seat is forward. The SDM monitors the SPS circuit and if a fault is detected the SDM will set codes B0083 or B0084 and defaults to disabling stage 2 frontal deployment. This will only default on the side of the vehicle the sensor has a fault. Its important to understand that the SPS is secondary to the passenger presence system (PPS) and the manual instrument panel (I/P) module disable switch. If either one of these devices are in the disable mode the passenger air bag will not deploy regardless of the SPS status.
You should take this to a qualified repair Shop ! Takes special tools to test .

What does the code b0026 mean on my 2009 buick lacrosse?


DTC B0026: Driver Frontal Deployment Loop (Stage 1) Open
It has to do with air bag system
B0026 Stage 1 or B0044 Stage 2 ?€¢
The steering wheel module stage 1 or stage 2 high circuit is less than 2.4 volts and the steering wheel module stage 1 or stage 2 deployment loop is more than 6 ohms for 500 milliseconds.


?€¢
The steering wheel module stage 1 or stage 2 deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.

How do I fix/reset code B0041


DTC B0041 will set when one of the following conditions occurs:
- The SDM detects the LF side impact module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
- The SDM detects the voltage at LF side impact module high control is less than 2.4 volts and LF side impact module deployment loop resistance is 6 ohms or greater for 500 milliseconds. it will continue to reset till the fault is repaired.

  • B0041
CIRCUIT DESCRIPTION
The inflatable restraint side impact module-LF deployment loop consists of the inflatable restraint side impact module-LF, the inflatable restraint side impact module wiring harness, and the side impact module-LF high and low circuits. A shorting bar used within the side impact module-LF connector shorts together the side impact module-LF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) allows current to flow through the deployment loop in order to deploy the side impact module-LF. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC
  • DTC B0040 will set when the side impact module-LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds .
  • DTC B0041 will set when one of the following conditions occurs:
  • Side impact module-LF high circuit is less than 2.4 volts and the side impact module-LF deployment loop is more than 6 ohms for 500 milliseconds .
  • Side impact module-LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds .
  • DTC B0045 will set when one of the following conditions occur:
  • Side impact module-LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds .
  • Side impact module-LF high circuit is less than 2.4 volts and side impact module-LF deployment loop resistance is less than 6 ohms for 500 milliseconds .
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC
  • The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
  • A history DTC will clear once 255 malfunction free ignition cycles have occurred.
DIAGNOSTIC AIDS
The following are possible causes of the malfunction:
  • A short between the side impact module-LF high and low circuits
  • An open or a high resistance in the side impact module-LF high or low circuits
  • A short to ground or a short to voltage in the side impact module-LF high or low circuits
  • The side impact module-LF connector
  • The SDM connector
  • A malfunctioning side impact module-LF
  • A malfunctioning SDM

2002 chevy truck.Code B0026


Hello and welcome. code B0026 is for a airbag malfunction. this code will require a high end scan tool, like a GM tech 2 scan tool to check out.this code is related to a deployment loop problem on the drivers side of vehicle

• DTC B0026 will set when one of the following conditions occurs:
- The SDM detects the steering wheel module deployment loop resistance is greater than 4.8 ? for 500 milliseconds. - The SDM detects the voltage at steering wheel module high signal is less than 2.4 volts and steering wheel module deployment loop resistance is 6 ? or greater for 500 milliseconds.The inflatable restraint steering wheel module deployment loop consists of a steering wheel module, steering wheel module coil, steering wheel module high signal circuit, and steering wheel module low signal circuit. Shorting bars are used on the steering wheel module connector as well as the steering wheel module coil connector which will short together the steering wheel module high and steering wheel module low signal circuits when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored.

What does code B0026 dr frontal deployment loop[stage 1 open] mean


This is usually due to an airbag deployment. It's the code for the front left circuit (driver's side). Most likely, the driver's side airbag deployed and the bag and module were replaced, but the module circuit ring in the column wasn't replaced. When the module senses the need to deploy, it sends a signal to the ring opening the line for the current to flow and causes the bag to deploy. Problem is, the circuit stays open, and casues a fault code. The unfortunate part is, until the curcuit is replaced, the SRS system in inoperable and will not deploy again in the event of an accident. You'll have to have the steering wheel pulled to service this item and should be done by a certified technician. It can be expensive, but worth the price of your safety.
