DTC B2800-49, B2801-49, B2802-49, C0061-96, U3000-49: Internal Failure of the SRS Unit
NOTE:
Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components of the correct part number and were properly installed.
Before troubleshooting any of these DTCs, check the 12 volt battery/system voltage and 12 volt battery cable connections. If the voltage is low, repair the charging system, test and charge the 12 volt battery, or replace the 12 volt battery before troubleshooting the SRS. If the 12 volt battery/system voltage is OK, ask the customer if the 12 volt battery ever went dead or if the engine was started and run with the 12 volt battery in a low state of charge. A dead 12 volt battery may trigger one or more of these DTCs.
Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
