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 used within the
air bag 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
The air bag 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
The air bag 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
The air bag 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
The air bag 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
The air bag or 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 SIR system 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:
• |
Passenger instrument panel air
bag |
• |
Driver and passenger seat side
air bags |
• |
Left and right roof rail air
bags |
• |
Driver and passenger
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 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.

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.

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.
