Condition
In extremely rare cases, some customers may comment that the air bag warning lamp is illuminated. This condition may be intermittent and when
checking the vehicle for DTCs, the SDM may report B0083, B0084, B0085, B0086, B0087 and/or B0088 with symptom code 0F. The code will be
stored in history and may be repeated. The code probably will not be current.
Cause
This condition may be caused by possible electro-magnetic interference (EMI) in the Amarillo, Texas area from external sources such as aviation
airspace traffic radar, creating erratic sensor information to the SDM.
Correction
Perform all diagnostics and repairs documented in SI.

Install a steward clamp ferrite bead following the procedure below:
1. Disconnect battery. Refer to SIR Disabling and Enabling in SI.
