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 air bag. 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, B0021 01, B0022 01, B0023 01

The air bag or retractor pretensioner control circuit is shorted to voltage for 2 seconds.

B0014 02, B0015 02, B0016 02, B0019 02, B0021 02, B0022 02, B0023 02

The air bag or retractor pretensioner control circuit is shorted to ground for 2 seconds.

B0014 04, B0015 04, B0016 04, B0019 04, B0021 04, B0022 04, B0023 04

The air bag or retractor pretensioner control circuit is open for 2 seconds.

B0014 0D, B0015 0D, B0016 0D, B0019 0D, B0021 0D, B0022 0D, B0023 0D

The air bag or retractor pretensioner deployment loop resistance is greater than 4.2 Ω for 2 seconds.

B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0021 0E, B0022 0E, B0023 0E

The air bag or retractor 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 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.

Diagnostic Aid

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 seat side air bags

•	Left and right roof rail air bags

•	Driver and passenger retractor 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 retractor pretensioner, passenger instrument panel or seat 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.

Circuit/System 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.

-	Seat belt retractor pretensioner

-	Passenger instrument panel air bag

-	Seat side air bag

-	Roof rail air bag

SDM

-	SDM 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.

•	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.

•	F105 Passenger instrument panel air bag, Roof rail air bag

•	F106 Seat side air bag

•	F112 Seat belt retractor pretensioner

•	Any inline harness

•

K36 SDM

⇒	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 Nyogel lubricant 760G to each connector terminal.

•	Insure each connector and CPA is correctly seated.

Circuit/System Testing

DTC B0014-B0018 or B0021-B0045

Ignition OFF, disconnect the harness connector at the appropriate F105, F106 air bags or F112 seat belt retractor pretensioner.
Ignition OFF, wait 60 seconds, test for greater than 25 Ω between the control circuit terminals listed below.
