DTC Descriptors
DTC B0052 00
Deployment Commanded
DTC B0052 56
Deployment Commanded Too Many Transitions
Circuit/System Description
The inflatable restraint sensing and diagnostic module (SDM) senses vehicle
impacts and provides deployment
signals to the air bags and anchor and/or retractor pretensioners when warranted.
The inflatable restraint sensing
and diagnostic module sets DTC B0052 after each command for deployment. DTC
B0052 will latch and not
clear after 3 commanded deployments by the inflatable restraint sensing and
diagnostic module. Therefore the
inflatable restraint sensing and diagnostic module has to be replaced.
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
Conditions for Setting the DTC
- The inflatable restraint sensing and diagnostic module detects a frontal
impact of sufficient force to
warrant deployment of the frontal air bags.
- The inflatable restraint sensing and diagnostic module detects a side
impact or rollover (if equipped) of
sufficient force to warrant deployment of a seat air bag and/or roof rail
air bag.
Action Taken When the DTC Sets
The inflatable restraint sensing and diagnostic module requests the
instrument cluster to illuminate the AIR
BAG indicator.
Conditions for Clearing the DTC
- DTC B0052 00 is a DTC that may be cleared with a scan tool without
replacing the inflatable restraint
sensing and diagnostic module. This DTC will not clear if deployment has
been commanded more then
two times, and the inflatable restraint sensing and diagnostic module would
have to be replaced.
- DTC B0052 56 is a latched DTC. The DTC cannot be cleared with the scan
tool. Replacement of the
inflatable restraint sensing and diagnostic module is required.

Restraint Sensing and
Diagnostic Module.
- If DTC B0052 00 is not set
- Verify that DTC B0052 56 is not set.
Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If DTC B0052 56 is not set
- All OK.
