Rollover/Impact Sensor Module - 2002 Corvette C5 LS1

The 2002 Chevrolet Corvette utilizes the Sensing and Diagnostic Module (SDM) as its central rollover/impact sensor, commonly identified by GM part numbers 16241665 or the later service replacement 25963394. This Delphi-manufactured unit fits all 1997-2004 C5 generation Corvettes regardless of body style, though installation requires dealer-level programming to marry the module to your specific VIN and airbag configuration. When sourcing from salvage yards, inspect the connector pins for green corrosion—particularly in convertibles where water intrusion plagues the console area—and verify the mounting bracket isn't cracked from prior impacts. The module mounts under the center console with specific orientation arrows that must face forward; incorrect mounting affects crash detection algorithms and may trigger fault codes. Always disconnect the battery and wait 30 seconds before removal to avoid deployment codes. Common failures include internal accelerometer faults triggering persistent airbag lights or communication errors on the Class 2 data bus.
