Circuit/System

Description

 

 

The seat position sensor is used to determine the proximity of a front driver

or passenger seat position with respect to the frontal air bag. There are two

states of seat position, forward and rearward. The seat position sensor

interfaces with the Inflatable Restraint Sensing and Diagnostic Module (SDM) and

allows the Inflatable Restraint Sensing and Diagnostic Module to disable stage 2

of the frontal air bag for a front seat that is forward of the forward/rearward

point in seat track. The seat position sensor provides 2 current ranges, one

range for the forward seat position and one for rearward seat position. When the

Inflatable Restraint Sensing and Diagnostic Module receives input from a seat

position sensor that the seat is rearward, and the Inflatable Restraint Sensing

and Diagnostic Module will not disable stage 2 deployment. When the seat is

forward, the Inflatable Restraint Sensing and Diagnostic Module will disable

stage 2 deployment. The Inflatable Restraint Sensing and Diagnostic Module

monitors the seat position sensor circuit and if a fault is detected, the

Inflatable Restraint Sensing and Diagnostic Module will set code B0079 or B0080

and disable stage 2 frontal deployment.

Circuit/System
Description

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 steering wheel air bag. The inflatable restraint
sensing and diagnostic module performs continuous diagnostic tests on the
deployment loops to check for proper circuit continuity and for shorts to ground
or voltage. There are 2 shorting bars used within the steering wheel air bag
coil connector which will short together both steering wheel air bag stage 1
high control circuit and steering wheel air bag stage 1 low control circuit and
both steering wheel air bag stage 2 high control circuit and steering wheel air
bag stage 2 low control circuit when the connector is disconnected. This will
help to prevent unwanted deployment of the steering wheel air bag during
servicing.

Conditions for Running the
DTC

Ignition voltage is between 9–16 V.

Conditions for Setting the
DTC

B0012 01 stage 1 or B0013 01 stage 2

The steering wheel air bag deployment loop is shorted to voltage for
2 seconds.

 

B0012 02 stage 1 or B0013 02 stage 2

The steering wheel air bag deployment loop is shorted to ground for
2 seconds.

 

B0012 04 stage 1 or B0013 04 stage 2

The steering wheel air bag deployment loop is open for 2 seconds.

 

B0012 0D stage 1 or B0013 0D stage 2

The steering wheel air bag deployment loop resistance is greater than 4.4 Ω
for 2 seconds.

 

B0012 0E stage 1 or B0013 0E stage 2

The steering wheel air bag deployment loop resistance is less than 1.7 Ω for
2 seconds.

 

Action Taken When the DTC
Sets

• The inflatable restraint sensing and diagnostic module requests the
  instrument cluster to illuminate the AIR BAG indicator.
• 
  
• The inflatable restraint sensing and diagnostic module will store a DTC,
  however if an event occurs the system will still attempt deployment.

Conditions for Clearing the
DTC

• The condition for setting the DTC is no longer exists.
• 
  
• A history DTC will clear once 100 malfunction-free ignition cycles have
  occurred.

Diagnostic Aid

Note: The following diagnostic aids apply for both current and history
DTCs.

A worn steering wheel air bag coil can cause a repeated history DTC to set.
To verify this condition, turn the steering wheel 360 degrees in one direction
then back 360 degrees in the other direction, multiple times, while viewing the
scan tool Deployment Loop Resistance parameters.

An incorrectly installed connector position assurance (CPA) or incorrectly
seated connector can cause a shorting bar to short both control circuits
together. Check the connectors and CPAs if a DTC with symptom byte 02 or 0E is
set, to ensure the shorting bars are not causing the circuits to be shorted
together. Shorting bars are used in the locations listed below:

• Steering wheel air bag assembly
• 
  
• Steering wheel air bag coil assembly
• 
  
• Inline harness connectors
• 
  
• Harness side of the inflatable restraint sensing and diagnostic module
  connector

Terminal fretting or incorrectly seated connector can cause an open/high
resistance condition. Check the circuit terminals for fretting or incorrectly
seated connector if a DTC with symptom byte 04 or 0D is set.

Verification

Note:

• Refer to SIR Service
  Precautions.
• 
  
• Inspect all terminals for damage or corrosion when disconnecting connectors.
  Damage or corrosion in the following requires repair or replacement of the
  affected component/connector.
  • Driver steering wheel air bag
  • 
    
  • Driver steering wheel air bag coil
  • 
    
  • Inflatable restraint sensing and diagnostic module
  • 
    
  • Air bag wiring harness connector
  • 
    
  • Inflatable restraint sensing and diagnostic module wiring harness
    connector
• 
  
• The connector and connector position assurance (CPA) may seat independent of
  each other. Both the connector and CPA should seat with an audible and/or
  tactile click. The CPA isolates the shorting-bars within the connector allowing
  the deployment circuit to operate properly. Replace any CPA that is damaged or
  missing.
• 
  
• If the condition is intermittent or cannot be duplicated, disconnect the
  connectors and add dielectric grease / lubricant (Nyogel 760G or equivalent,
  meeting GM specification 9986087). This procedure will correct the high
  resistance condition due to terminal fretting corrosion.

2. Verify the appropriate scan tool Deployment Loop Resistance
   parameters stay consistently between 2.1–4.0 Ω without any spikes or dropouts
   while turning the steering wheel 360 degrees in one direction then back 360
   degrees in the other direction.
   • If less than 2.1 Ω or greater than 4.0 Ω
     
     

     Refer to Circuit/System Testing.

   • 
     
   • If there are spikes or dropouts
     

     Replace the steering wheel air bag coil.

   
   
   • If between 2.1–4.0 Ω without any spikes or
     dropouts
3. 
   
4. Verify DTC B0012 or B0013 is only set as a history DTC.
   • If the DTC is set as current
     

     Refer to Circuit/System Testing.

   
   
   • If the DTC is set as history
5. 
   
6. Verify the scan tool Deployment Loop Resistance parameters
   stay consistently between 2.1–4.0 Ω without any drop outs or spikes while moving
   the harness near each connector listed below.
   • Steering wheel air bag coil
   • 
     
   • Steering wheel air bag.
   • 
     
   • Any inline harness connector
   • 
     
   • Inflatable restraint sensing and diagnostic module
   
   
   • If the reading is erratic while moving the
     harness, perform the following
   
   
   • Inspect each connector terminal for damage or corrosion and repair as
     necessary.
   • 
     
   • Apply dielectric grease / lubricant (Nyogel 760G or equivalent, meeting GM
     specification 9986087) to each connector terminal.
   • 
     
   • Ensure each connector and CPA is correctly seated.
   
   
   • If between 2.1–4.0 Ω without any spikes or
     dropouts
7. 
   
8. All OK.
