Transfer Case Control Module for GM 2-Speed Systems

Dorman 599-192 is a replacement transfer case control module for select GM trucks and SUVs with electric shift, 2-speed transfer cases. It restores transfer case control on vehicles equipped with RPO code NQH and is built to match the function and performance of the original module.

Key Features

  • Replacement transfer case control module for electric shift MP2023/3024 systems
  • Black connector color with pin-style terminals
  • Direct-fit service part for select Chevrolet and GMC applications
  • Addresses transfer case control issues without replacing the entire transfer case assembly
  • Cross-reference: GM OE 12588096

Detailed Description

This Dorman transfer case control module is engineered for select Chevrolet Silverado, Suburban, Tahoe, Avalanche, and GMC Sierra, Yukon, and Yukon XL models with a switch-activated 2-speed transfer case. Part number 599-192 is a practical OE-style replacement when the original module no longer commands the transfer case correctly. It is designed for vehicles using electric shift MP2023/3024 hardware and RPO code NQH.

Compatible With 2007-2014 Chevrolet Silverado 2500, 2007-2014 Chevrolet Silverado 2500 HD, 2007-2014 Chevrolet Silverado 3500 HD, 2007-2014 Chevrolet Suburban 1500, 2008-2014 Chevrolet Tahoe, 2008-2014 GMC Sierra 2500 HD, 2007-2014 GMC Sierra 3500 HD, 2008-2014 GMC Yukon, 2008-2014 GMC Yukon XL 1500, 2008-2013 Chevrolet Avalanche, 2007-2013 Chevrolet Silverado 1500, 2007-2013 Chevrolet Suburban 2500, 2007-2013 GMC Sierra 1500, and 2008-2013 GMC Yukon XL 2500. Dorman 599-192 also serves as a direct replacement for GM OE 12588096.

What It Helps Fix

  • Transfer case not shifting between 2WD and 4WD modes
  • Intermittent or inoperative switch-activated transfer case control
  • Faults caused by a failed original control module
  • Loss of proper communication between the dash switch and transfer case system
  • Need for a cost-effective replacement versus full transfer case service

Installation Notes and Tips

Verify the vehicle uses electric shift MP2023/3024 with RPO code NQH before ordering. Confirm connector style, terminal type, and module location against the original part. After installation, follow the vehicle service procedure for module initialization or system relearn if required by the application.

Quality Assurance

Dorman supplies replacement parts that mirror the original part’s function and performance on the listed applications. This module is built for the specified GM fitments and supports service replacement for the original control unit.
