Circuit/System Description
During a side or frontal crash of sufficient force the Inflatable Restraint Sensing and Diagnostic Module will allow
current to flow through the deployment loop in order to deploy an air bag or pretensioner. There are 2 shorting bars
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
https://www.motologic.com/car/2014_chevrolet_equinox_100300468/article/76a01d45c6d6d3382f140fa0b7ec2380 2/7

B0015 01, B001A 01, B001B 01, B0022 01
The pretensioner control circuit is shorted to voltage for 2 seconds.
B0015 02, B001A 02, B001B 02, B0022 02
The pretensioner control circuit is shorted to ground for 2 seconds.
B0015 04, B001A 04, B001B 04, B0022 04
The pretensioner control circuit is open for 2 seconds.
B0015 0D, B001A 0D, B001B 0D, B0022 0D
The pretensioner deployment loop resistance is greater than 4.2 Ω for 2 seconds.
B0015 0E, B001A 0E, B001B 0E, B0022 0E
The pretensioner deployment loop resistance is less than 1.4 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 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:
Driver and passenger anchor or retractor pretensioners
Inline connectors – on the side of the harness connector
Harness side of the inflatable restraint sensing and diagnostic module connector
Terminal fretting or incorrectly seated connectors 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. DTCs of
deployment loops which are in the seat 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.

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
Seat belt retractor pretensioner wiring harness connector
Seat belt anchor pretensioner
Seat belt anchor pretensioner wiring harness connector
Inflatable Restraint Sensing and Diagnostic Module
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.
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.
1. Verify the scan tool Deployment Loop Resistance parameters stay consistently between 2.1 and 4.0 Ω
without any spikes or dropouts while moving the harness near each connector listed below:
F112 Seat Belt Retractor Pretensioner
F113 Seat Belt Anchor Pretensioner
Any inline harness

3/4/2021 DTC B0015, B001A, B001B, or B0022 • 2014 Chevrolet Equinox • MotoLogic
If less than 2.1 or greater than 4.0 Ω
Refer to Circuit/System Testing.
If there are spikes or dropouts, perform the following
Inspect each connector terminal and harness 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 within 2.1 and 4.0 Ω without any spikes or dropouts
All OK.
Circuit/System Testing
1. Ignition OFF, disconnect the scan tool. It may take up to 2 minutes for all vehicle systems to power down.
Disconnect the appropriate harness connector listed below:
F112 Seat Belt Retractor Pretensioner
F113 Seat Belt Anchor Pretensioner
Test for greater than 25 Ω between the appropriate control circuit terminals listed below:
F112 Seat Belt Retractor Pretensioner terminals 1 and 2
F113 Seat Belt Anchor Pretensioner terminals 1 and 2
If 25 Ω or less
1. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
Note: Some connectors may be equipped with shorting bars as a safety component to prevent accidental
inflator deployment. When testing on a connector with shorting bars, the shorting bars must be disabled to
ensure accurate test results. Insert an appropriate pick from EL-38125-580 and depress the shorting bars
above the appropriate terminals. This will lift the shorting bar from the terminal and allow accurate test
results. Take care not to damage the connector, shorting bar, or terminal when depressing the shorting
bar.
2. Test for infinite resistance between the 2 control circuits.
If less than infinite resistance, repair the short between the two circuits.
If infinite resistance, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
If greater than 25 Ω
Ignition ON.
Test for less than 11 V between the control circuit terminals listed below and ground:
F112 Seat Belt Retractor Pretensioner terminal 1
F112 Seat Belt Retractor Pretensioner terminal 2
F113 Seat Belt Anchor Pretensioner terminal 1
F113 Seat Belt Anchor Pretensioner terminal 2
If 11 V or greater
1. Ignition OFF, disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic
Module, ignition ON.

2. Test for less than 1 V between each control circuit and ground.
If 1 V or greater, repair the short to voltage on the circuit.
If less than 1 V, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
If less than 11 V
Ignition OFF. It may take up to 2 minutes for all vehicle systems to power down.
Test for greater than 25 Ω between the control circuit terminals listed below and ground:
F112 Seat Belt Retractor Pretensioner terminal 1
F112 Seat Belt Retractor Pretensioner terminal 2
F113 Seat Belt Anchor Pretensioner terminal 1
F113 Seat Belt Anchor Pretensioner terminal 2
If 25 Ω or less
1. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
2. Test for infinite resistance between each control circuit and ground.
If less than infinite resistance, repair the short to ground on the circuit.
If infinite resistance, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
If greater than 25 Ω
Install a 3 A fused jumper wire between the appropriate control circuit terminals listed below:
F112 Seat Belt Retractor Pretensioner terminals 1 and 2
F113 Seat Belt Anchor Pretensioner terminals 1 and 2
Ignition ON.
Verify the scan tool Deployment Loop Resistance parameter is less than 2 Ω.
If 2 Ω or greater
1. Ignition OFF.
2. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
3. Test for less than 2 Ω in each control circuit end to end.
If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
If less than 2 Ω
Ignition OFF, connect the harness connector at the F112 Seat Belt Retractor Pretensioner or F113 Seat Belt
Anchor Pretensioner, press in the CPA (if equipped) until an audible and/or tactile click is heard.
Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
Verify DTC B0015, B001A, B001B, or B0022 is not set.
If B0015, B001A, B001B, or B0022 is set
Replace the appropriate F112 Seat Belt Retractor Pretensioner or F113 Seat Belt Anchor Pretensioner.
If DTC B0015, B001A, B001B, or B0022 is not set
All OK.
