* 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.

2010 Cadillac Truck SRX AWD V6-3.0L Page 1228 Circuit/System Testing Note: You must perform the Circuit/System Verification before proceeding with Circuit/System Testing. 1. Ignition OFF, disconnect the harness connector at the S87 fuel economy mode switch. Note: It may take up to 2 minutes for all vehicle systems to power down. 2. Ignition OFF and all vehicle systems OFF, test for less than 5 ohm between ground circuit terminal 2 of the harness connector and ground. 瀚慖f greater than the specified value, test the ground circuit for an open/high resistance and repair as necessary. 3. Ignition ON, test for 4.8-5.2 V between 5 V reference circuit terminal 9 of the harness connector and ground. 瀚慖f less than the specified range, test the 5 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K20 ECM. 瀚慖f greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the
