If the vehicle interior is exposed to moisture and becomes soaked up to the level of the sensing and diagnostic module (SDM), the SDM and SDM harness connector must be replaced. The SDM could be activated when powered, which could cause airbag deployment and result in personal injury.
Yes, a new or used replacement
Supplemental Restraint Module (SDM) on a 2003 Chevy Tahoe needs to be programmed using a specialized scan tool (like a
GM Tech 2
or equivalent).
Failure to program the module will result in the airbag warning light staying on and the system not functioning correctly in the event of an accident. You will likely encounter a configuration error code, such as B1001.
