U058DInvalid Data Received From Active Grille Air Shutter Module D
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Module D is the fourth shutter position the code list reserves; it only matters on front ends with four separately driven flap sets, for instance two upper and two lower ones. No manufacturer documents U058D or names a shutter D in public material, so its exact placement remains maker-specific. The code means that frames from that actuator reach the engine controller but are judged unusable, for example because the alive counter stalls or the checksum is wrong; GM's shutter B check in the 2025 tables (25OBDG04B) shows the usual form of such a test, with MIL after two trips. CARB lists grill shutters among active off-cycle technologies whose activity must be tracked. In practice the affected flaps freeze, which barely changes driving. U028C covers total loss of the module.
- What you may notice
