| Circuit/System Description |
During a side or 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 an inflatable restraint module. There are 2 shorting bars used within the module connector which will short together control circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the air bag or pretensioner during servicing.
| Conditions for Running the DTC |
Ignition voltage is between 9-16 V.
| Conditions for Setting the DTC |
B0014 01, B0015 01, B0016 01, B0019 01, B0020 01, B0021 01, B0022 01, B0023 01, B0031 01, B0038 01
The inflatable restraint module or pretensioner control circuit is shorted to voltage for 2 seconds.B0014 02, B0015 02, B0016 02, B0019 02, B0020 02, B0021 02, B0022 02, B0023 02, B0031 02, B0038 02
The inflatable restraint module or pretensioner control circuit is shorted to ground for 2 seconds.B0014 04, B0015 04, B0016 04, B0019 04, B0020 04, B0021 04, B0022 04, B0023 04, B0031 04, B0038 04
The inflatable restraint module or pretensioner control circuit is open for 2 seconds.B0014 0D, B0015 0D, B0016 0D, B0019 0D, B0020 0D, B0021 0D, B0022 0D, B0023 0D, B0031 0D, B0038 0D
The inflatable restraint module or pretensioner deployment loop resistance is greater than 4.2 Ω for 2 seconds.B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E, B0031 0E, B0038 0E
The inflatable restraint module or pretensioner deployment loop resistance is less than 1.4 Ω for 2 seconds.| Action Taken When the DTC Sets |
| • |
The SDM requests the instrument cluster to illuminate the AIR BAG indicator.
|
|
| • |
The SDM will store a DTC, however if an event occurs the system will still attempt deployment.
|
|
| Conditions for Clearing the DTC |
| • |
The condition responsible for setting the DTC no longer exists.
|
|
| • |
A history DTC will clear once 100 malfunction-free ignition cycles have occurred.
|
|
| Diagnostic Aids |
| Note | ||
|
The following diagnostic aids apply for both current and history DTCs. |
An incorrectly installed 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:
| • |
Passenger instrument panel air bag
|
|
| • |
Driver and passenger side airbags
|
|
| • |
Left and right roof rail airbags
|
|
| • |
Driver and passenger pretensioners
|
|
| • |
Inline connectors - on the side of the harness connector
|
|
| • |
Harness side of the SDM 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. If DTCs of deployment loops which are in the seat DTC B0014 and B0021, can occur because of stress or damage to the harness due to seat movement. Move the seat to the full extend of travel while using the scan tool to observe deployment type loop parameters.
If the pretensioner, passenger instrument panel or side air bag has inflated under unexpected conditions and/or DTC with symptom byte 01 is set, check both control circuits for a short to voltage.

| 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. |
||
| • |
Belt Tensioner
|
|
| • |
Passenger instrument panel airbag
|
|
| • |
Side air bag
|
|
| • |
Roof rail airbag
|
|
| • |
SDM
|
|
| • |
SDM wiring harness connector
|
|
| Note | ||
|
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. |
||
|
If the condition is intermittent or cannot be duplicated, disconnect the connectors and add Nyogel lubricant 760G. This procedure will correct the high resistance condition due to terminal fretting corrosion. |
Observe the scan tool Deployment Loop Resistance parameters while moving the harness near each connector listed below. The reading should stay consistently between 1.7 and 4.2 Ω without any drop outs or spikes.

|
| • |
Inspect each connector terminal for damage or corrosion and repair as necessary.
|
|
| • |
Apply Nyogel lubricant 760G to each connector terminal.
|
|
| • |
Insure each connector and CPA is correctly seated.
