### 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 both high and low circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module 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, B0018 01, B0019 01, B0020 01, B0021 01, B0022 01, B0023 01, B0025 01

The inflatable restraint module high and/or low control circuit is shorted to voltage for 2 seconds.

#### B0014 02, B0015 02, B0016 02, B0018 02, B0019 02, B0020 02, B0021 02, B0022 02, B0023 02, B0025 02

The inflatable restraint module high and/or low control circuit is shorted to ground for 2 seconds.

#### B0014 04, B0015 04, B0016 04, B0018 04, B0019 04, B0020 04, B0021 04, B0022 04, B0023 04, B0025 04

The inflatable restraint module high and/or low control circuit is open for 2 seconds.

#### B0014 0D, B0015 0D, B0016 0D, B0018 0D, B0019 0D, B0020 0D, B0021 0D, B0022 0D, B0023 0D, B0025 0D

The inflatable restraint module deployment loop resistance is greater than 5.5 Ω for 2 seconds.

#### B0014 0E, B0015 0E, B0016 0E, B0018 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E, B0025 0E

The inflatable restraint module deployment loop resistance is less than 1.1 Ω for 2 seconds.

### Action Taken When the DTC Sets

• | The SDM requests the instrument panel cluster to illuminate the AIR BAG indicator.

• | The SDM will store a DTC, however if an event occurs the system will still attempt deployments.

### Conditions for Clearing the DTC

• | The condition for setting the DTC no longer exists.

• | A history DTC will clear once 100 malfunction-free ignition cycles have occurred.

### Circuit/System Testing

Note: Refer to SIR Service Precautions.

When removing connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:

• | Pretensioner

• | Inflatable restraint module

• | SDM module

• | Inflatable restraint module wiring harness connector

• | 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.

1. Ignition OFF, disconnect the appropriate inflatable restraint module connector.
2. Ignition ON, verify that the scan tool Deployment Loop Resistance parameter is infinite resistance at the control circuits.

⇒ | If less than the specified value, test the control circuits for a short to ground. If the circuits test normal, replace the K36 SDM.

3. Connect a fused jumper wire between the appropriate control circuit terminals listed below:

• | F105 I/P module stage 1 terminal 1 and terminal 2

• | F105 I/P module stage 2 terminal 4 and terminal 5

• | F105L left roof rail module terminal 1 and terminal 2

• | F105R right roof rail module terminal 1 and terminal 2

• | F106LF left front side impact module terminal 1 and terminal 2

• | F106RF right front side impact module terminal 1 and terminal 2

• | F106LR left rear side impact module terminal 1 and terminal 2

• | F106RR right rear side impact module terminal 1 and terminal 2

• | F109D driver seat belt buckle pretensioner terminal 1 and terminal 2

• | F109P passenger seat belt buckle pretensioner terminal 1 and terminal 2

4. Ignition ON, verify that the scan tool Deployment Loop Resistance parameter is less than 1.8 Ω at the control circuits.

⇒ | If greater than the specified range, test the control circuits for a short to voltage or an open/high resistance. If the circuits test normal, replace the K36 SDM

5. If all circuits test normal, replace the inflator restraint module.
