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.
