Control – GM (42794749)

GM lists this control under number 42794749. It is catalogued under Electrical Components > Control Units.

• Hybrid
• Cameras and sensors used by driver-assist systems normally need calibration after replacement, and the cost of that belongs in the decision.
• Terminal tension is the usual cause of an intermittent fault, so a harness repair should include new terminals rather than straightened ones.

Match electrical parts on the option code as well as the model year, because the same body can carry different modules depending on how it was built.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Leaves our US warehouse in one to two business days, and shipping is free over $59.
