Diagnostic Trouble Code (DTC) List

Circuit Description

The dual stage inflatable restraint IP module deployment loop consists of the dual stage inflatable restraint IP module, and the IP module high and low circuits for both stages 1 and 2. Two shorting bars used within the IP module connector short together both the IP module stage 1 high and low circuits, and the IP module stage 2 high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a 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 IP module. 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

1. DTC B0012 in stage 2 or B0016 in stage 1 will set when the IP module deployment loop resistance is less than 1.3 ohms for 500 milliseconds.

DTC B0051

The inflatable restraint sensing and diagnostic module (SDM) contains sensing devices that convert vehicle velocity changes to electrical signals. The SDM processes the generated electrical signals and compares them to values stored in memory. When the generated signals exceed the stored values, the SDM performs additional signal processing and compares the generated signals to signals stored in memory. When 2 of the generated signals exceed the stored values, the SDM will cause current to flow through the inflator modules, deploying the inflator modules. Diagnostic trouble code (DTC) B0053 will set along with DTC B0051 when a deployment occurs while a circuit malfunction is present in any one of the deployment loops.

The inflatable restraint side impact sensor (SIS) utilizes a unidirectional 2-wire circuit. The SIS modulates current on the interface to send ID, State of Health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and a ground for the SIS. When the ignition is turned on and input power from the SDM is first detected, the SIS responds by performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds. The SIS continually communicates status messages to the SDM, which determines if a fault is present in the SIS circuit. When a fault is detected, the SDM may reset the SIS up to two times by removing and reapplying power to it. If the fault is still present, the SDM will set a diagnostic trouble code (DTC).

Ignition 1 Voltage is within the normal operating voltage range of 9-16 volts.

2. Mounting points or mounting hardware for the inflatable restraint SDM - Inspect for any damage and repair or replace each component as needed.

Sensor Replacement Guidelines

The SIS replacement policy requires replacing sensors in the area of accident damage. The area of accident damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision.

1. Replace the sensor whether or not the air bags have deployed.
2. Replace the sensor even if it appears to be undamaged.

Sensor damage which is not visible, such as a slight bending of the mounting bracket or cuts in the wire insulation, can cause improper operation of the sensor. Do not try to determine whether the sensor is undamaged, replace the sensor.

Live and Undeployed Inflator Module

Scheme 14

Take special care when handling or storing a live (undeployed) inflator module. An inflator module deployment produces a rapid generation of gas. This may cause the inflator module, or an object in front of the inflator module, to project through the air in the event of an unlikely deployment.

Dual Stage Inflator Module

Dual stage inflator modules have two deployment stages. If stage 1 was used to deploy a dual stage inflator module, stage 2 may still be active. Therefore, a deployed inflator module must still be treated as an active inflator module. If disposal of a deployed or undeployed dual stage module is required, both deployment loops must be energized to deploy the inflator module.

Scrapping Procedure

During the course of a vehicle's useful life, certain situations may arise which will require the disposal of a live and undeployed inflator module. Do not dispose a live and undeployed inflator module through normal disposal channels until the inflator module has been deployed. If scrapping a deployed dual stage inflator module, both stages must be energized. The following information covers the proper procedures for the disposing of a live and undeployed inflator module. Do not deploy the inflator module in the following situations

1. After replacement of an inflator module under warranty. The inflator module may need to be returned undeployed to the manufacturer.
2. If the vehicle is the subject of a product liability report, GM-1241, related to the SIR or seat belt system. When a vehicle is the subject of a product liability report, do not alter the SIR or seat belt system in any manner.
3. If the vehicle is involved in a campaign affecting the inflator modules. Follow the instructions in the campaign service bulletin for proper SIR handling procedures.

Deployment Procedures

The inflator module can be deployed inside or outside of the vehicle. The method used depends upon the final disposition of the vehicle. Review the following procedures in order to determine which will work best in a given situation

Deployment Outside Vehicle - Steering Wheel Module, IP Module, and Side Impact Module

Deploy the inflator module outside of the vehicle when the vehicle will be returned to service. Situations that require deployment outside of the vehicle include the following

1. Using the SIR diagnostics, you determine that the inflator module is malfunctioning.
2. The inflator module is cosmetically damaged, scratched, or ripped.
3. The inflator module pigtail, if equipped, is damaged.
4. The inflator module connector is damaged.
5. The inflator module connector terminals are damaged.

Deployment and disposal of a malfunctioning inflator module is subject to any required retention period.

SIR System Overview

The supplemental inflatable restraint (SIR) system supplements the protection offered by the occupant seat belt system (2). The SIR system has several inflator modules that are located throughout the vehicle. They are the following

Scheme 15

1. Inflatable restraint steering wheel module (1)
2. Inflatable restraint I/P module (1)
3. Inflatable restraint side impact module-LF
4. Inflatable restraint side impact module-RF
5. Inflatable restraint seat belt pretensioner-LF, Buick
6. Inflatable restraint seat belt pretensioner-RF, Buick

Each inflator module has a deployment loop that is controlled by the inflatable restraint sensing and diagnostic module (SDM), which is mounted inside the vehicle. The SDM determines the severity of a collision with the assistance of various sensor inputs. When the SDM detects a collision of sufficient force, it processes the information provided by the sensors to further support air bag or pretensioner deployment. The SDM will deploy the frontal air bags and pretensioners if it detects a collision of sufficient force. If the force of the impact is not sufficient to warrant inflator module deployment, the SDM may still deploy the seat belt pretensioners. The SDM performs continuous diagnostic monitoring of the SIR system electrical components. Upon detection of a circuit malfunction, the SDM will set a diagnostic trouble code (DTC) and inform the driver by commanding the instrument panel cluster (IPC) to turn the AIR BAG indicator ON. The steering column and knee bolsters (3) are designed to absorb energy and compress during frontal collisions in order to limit leg movement and decrease the chance of injury to the driver and front passenger.

Frontal SIR System Description

The frontal SIR system consists of the following components

1. AIR BAG indicator located in the instrument panel cluster (IPC)
2. Driver and front passenger knee bolsters
3. Inflatable restraint front end sensor (EFS) - Left, Buick
4. Inflatable restraint front end sensor (EFS) - Right, Buick
5. Inflatable restraint instrument panel (I/P) module
6. Inflatable restraint seat belt pretensioner-LF, Buick
7. Inflatable restraint seat belt pretensioner-RF, Buick
8. Inflatable restraint sensing and diagnostic module (SDM)
9. Inflatable restraint steering wheel module
10. Inflatable restraint steering wheel module coil
11. Inflatable restraint wiring harnesses
12. Steering wheel and steering column

A frontal collision of sufficient force will deploy the frontal inflator modules. The SDM contains a sensing device that converts vehicle velocity changes to an electrical signal. In some vehicles, the SDM receives a signal from the EFS-Left and EFS-Right which can help determine the severity of some types of frontal collisions. The SDM contains a microprocessor, which performs calculations using the measured accelerations and compares these calculations to a value stored in memory. When the generated calculations exceed the stored value, the SDM will cause current to flow through the frontal deployment loops, deploying the frontal inflator modules. Once the inflator modules are inflated, they quickly deflate through the air bag vent holes and/or the bag fabric. After the inflator modules are deployed, the SDM sets a deployment commanded diagnostic trouble code (DTC) and then commands the IPC to turn the AIR BAG indicator ON. The SDM, I/P module, steering wheel module, steering wheel module coil, and the connecting wires make up the frontal deployment loops. The SDM continuously monitors the deployment loops for malfunctions and commands the IPC to turn the AIR BAG indicator ON if a fault is detected.

Inflatable Restraint Sensing and Diagnostic Module (SDM)

The inflatable restraint sensing and diagnostic module (SDM) is a microprocessor and the control center for the supplemental inflatable restraint (SIR) system. The SDM contains internal sensors along with external sensors mounted at various locations, depending on vehicle. In the event of a collision, the SDM performs calculations using the signals received from the internal and external sensors. The SDM compares the result of the calculations to values stored in memory. When these calculations exceed the stored value, the SDM will cause current to flow through the deployment loops, deploying the inflator modules. The SDM records the SIR system status when a deployment occurs and commands the instrument panel cluster (IPC) to turn the AIR BAG indicator ON. The SDM performs continuous diagnostic monitoring of the SIR system electrical components and circuitry when the ignition is ON. If the SDM detects a malfunction, a DTC will be stored and the SDM will turn the AIR BAG indicator ON. In the event that ignition 1 voltage is lost during a collision, the SDM maintains a 36-volt loop reserve (36 VLR) for deployment of the inflator modules. It is important to note, when disabling the SIR system for service or rescue operations, to allow the 36 VLR to dissipate, which could take up to 1 minute.

AIR BAG Indicator

The AIR BAG indicator, located in the instrument panel cluster (IPC) is used to notify the driver of supplemental inflatable restraint (SIR) system malfunctions and to verify that the inflatable restraint sensing and diagnostic module (SDM) is communicating with the IPC. When the ignition is turned ON, the SDM and the IPC are supplied with ignition 1 voltage. The IPC responds by flashing the AIR BAG indicator seven times. While the IPC is flashing the AIR BAG indicator, the SDM conducts tests on all SIR system components and circuits. If no malfunctions are detected, the SDM will command the IPC to turn the AIR BAG indicator OFF via Class 2 serial data. The SDM provides continuous monitoring of the inflator module circuits by conducting a sequence of checks. If a malfunction is detected, the SDM will store a DTC and command the IPC to turn the AIR BAG indicator ON via Class 2 serial data. The presence of a SIR system malfunction could result in non-deployment of the inflator modules in the event of a collision, or deployment of the inflator modules without the event of a collision. The AIR BAG indicator will remain ON until the malfunction has been repaired.

Inflator Modules

The inflator modules consist of a housing, an inflatable air bag, the initiator, a canister of gas generating materials, and in some cases, stored compressed gas. The initiator is part of the inflator module deployment loop. When the vehicle is involved in a collision of sufficient force, the SDM causes current to flow through the deployment loops to the initiator. Current passing through the initiator ignites the material in the canister producing a rapid generation of gas and the release of compressed gas, if present. The gas produced from this reaction rapidly inflates the inflator module. Once the inflator module is inflated, it quickly deflates through the vent holes and/or the fabric. Each inflator module is equipped with a shorting bar that is located in the connector of the inflator module. The shorting bar shorts the inflator modules circuitry to prevent unwanted deployment of the inflator module when the connector is disconnected.

Dual stage inflator modules consist of a housing, inflatable air bag, 2 initiating devices, a canister of gas generating material, and in some cases stored compressed gas. The 2 initiators are part of the frontal deployment loop. The function of the frontal deployment loops are to supply current through the steering wheel and instrument panel (I/P) inflator modules to deploy the air bags. The inflator modules have 2 stages of deployment, which varies the amount of restraint to the occupant according to the collision severity. For moderate frontal collisions, the inflator modules deploy at less than full deployment, or low deployment, which consists of stage 1 of the inflator module. For more severe frontal collisions, a full deployment is initiated which consists of stage 1 and stage 2 of the inflator module. The current passing through the initiators ignite the material in the canister producing a rapid generation of gas and in some cases, the release of compressed gas. The gas produced from this reaction rapidly inflates the air bag. Once the air bag is inflated, it quickly deflates through the air bag vent holes and/or the bag fabric. Each dual stage inflator module is equipped with a shorting bar located in the connectors of the module. The shorting bar shorts the inflator module deployment loop circuitry to prevent unwanted deployment of the air bag when it is disconnected.

Inflatable Restraint Seat Belt Pretensioners, Buick

The seat belt pretensioners consist of a housing, a seat belt retractor, the seat belt webbing, an initiator, and a canister of gas generating materials. The initiator is part of the seat belt pretensioner deployment loop. When the vehicle is involved in a collision of sufficient force, the inflatable restraint sensing and diagnostic module (SDM) causes current to flow through the seat belt deployment loops to the initiator. Current passing through the initiator ignites the material in the canister producing a rapid generation of gas. The gas produced from this reaction deploys the seat belt pretensioners and retracts the seat belt webbing, which removes all of the slack in the seat belts. Depending on the severity of the collision, the seat belt pretensioners may deploy without the frontal inflator modules deploying, or they will deploy immediately before the frontal inflator modules deploy. After a single pretensioner only deployment, the SDM will set DTC B0051 or B0053 and will need to be replaced. Each seat belt pretensioner is equipped with a shorting bar that is located in the connector of the seat belt pretensioner. The shorting bar shorts the seat belt pretensioner circuitry to prevent unwanted deployment of the seat belt pretensioner when the connector is disconnected.

Inflatable Restraint Steering Wheel Module Coil

The steering wheel module coil is attached to the steering column and is located under the steering wheel. The steering wheel module coil consists of two or more current-carrying coils. The coils allow the rotation of the steering wheel while maintaining continuous electrical contact between the steering wheel module deployment loop and the steering wheel module. Two coil wires are used for the steering wheel module deployment loop. Additional coil wires are used for accessories that are attached to the steering wheel, depending on the vehicle model. The steering wheel module coil connector is located near the base of the steering column. The connector contains a shorting bar that shorts the steering wheel module coil deployment loop circuitry to prevent unwanted deployment of the steering wheel module when the connector is disconnected.

Inflatable Restraint Front End Sensor (EFS), Buick

The front end sensors (EFS), also known as the inflatable restraint electronic frontal sensor, is equipped on vehicles to supplement the SIR system performance. Each EFS is an electronic sensor and is not part of the deployment loops, but instead provides an input to the inflatable restraint sensing and diagnostic module (SDM). Each EFS can assist in determining the severity of some frontal collisions. The SDM contains a microprocessor which performs calculations using the measured accelerations and compares these calculations to a value stored in memory. When the generated calculations exceed the stored value, the SDM will cause current to flow through the frontal deployment loops, deploying the frontal air bags.

Side SIR System Description

The side impact SIR system consists of the following components

1. AIR BAG indicator in the instrument panel cluster (IPC)
2. Inflatable restraint sensing and diagnostic module (SDM)
3. Inflatable restraint side impact modules-LF
4. Inflatable restraint side impact modules-RF
5. Inflatable restraint side impact sensors (SIS)-LF
6. Inflatable restraint side impact sensors (SIS)-RF
7. Inflatable restraint seat belt pretensioner-LF, Buick
8. Inflatable restraint seat belt pretensioner-RF, Buick

The side impact modules are located in the outside portion for the front seat backs. The side impact modules consist of a housing, inflatable air bag, initiating device, and a canister of gas generating material. The initiator is part of the side impact module deployment loop. When a side impact of sufficient force occurs, the SIS detects the impact and sends a signal to the SDM. The SDM compares the signal received from the SIS to a value stored in memory. When the generated signal exceeds the stored value, the SDM will cause current to flow through the side deployment loop, deploying the inflator module. The SDM, side impact modules, and the connecting wires make up the side deployment loops. The SDM continuously monitors the side deployment loops for malfunctions and commands the IPC to turn the AIR BAG indicator ON if a fault is present. Each side impact module is equipped with a shorting bar located in the connector of the module. The shorting bar shorts the side impact module deployment loop circuitry to prevent unwanted deployment of the air bag when it is disconnected.

Inflatable Restraint Side Impact Sensor (SIS)

The side impact sensors (SIS) contain a sensing device which monitors vehicle acceleration and velocity changes to detect side collisions that are severe enough to warrant side inflator module deployment. Each SIS is not part of the deployment loop, but instead provides an input to the inflatable restraint sensing and diagnostic module (SDM). The SDM contains a microprocessor that performs calculations using the measured accelerations and compares these calculations to a value stored in memory. When the generated calculations exceed the stored value, the SDM will cause current to flow through the deployment loops, deploying the side air bags.

Steering Wheel and Column

The steering wheel and column are designed to absorb energy when driver contact is made with the steering wheel or an inflated module. In a collision, the driver may contact the steering wheel directly or load the steering wheel and column through the inflated module. When the driver applies load to the inflator module or the steering wheel, the column will compress downward, absorbing some of the impact and helping to reduce bodily injuries to the driver. The steering wheel and column must be inspected for damages after a collision.

Inflatable Restraint Wiring Harness

The inflatable restraint wiring harness connects the inflator modules, the inflatable restraint sensing and diagnostic module (SDM), the deployment loops, and the serial data circuit together using weather-packed connectors. Supplemental inflatable restraint (SIR) system connectors are yellow for easy identification. When repairing SIR wiring harnesses, follow the proper testing and repair procedures listed in the service manual.

Knee Bolster

The knee bolsters are designed to help restrain the lower torso of front seat occupants by absorbing the energy through the front seat occupant's upper legs. In a collision, the front seat occupants legs may come in contact with the knee bolsters. The knee bolsters are designed to crush and deform, absorbing some of the impact and helping to reduce bodily injuries. The driver and passenger knee bolsters are located in the lower part of the instrument panel and must be inspected for damages after a collision.
