The air bag or retractor pretensioner deployment loop resistance is greater than 4.2 ohm for 2 seconds.
B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E
The air bag or retractor pretensioner deployment loop resistance is less than 1.4 ohm 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 seat belt retractor pretensioners
* SDM
* 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 pretensioner, passenger instrument panel or 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.
