To replace the Transfer Case Control Module (TCCM) on a 2002 Chevy Trailblazer, first, disconnect the negative battery cable to avoid any electrical issues. Locate the TCCM, which is typically found under the vehicle near the transfer case, and remove any necessary covers or shields. Unplug the electrical connector and remove the mounting bolts to take out the old module. Install the new TCCM by reversing the removal steps, ensuring all connections are secure before reconnecting the battery.

How do you replace a transfer case control module on a 2002 Chevy trailblazer?
The TCCM is on the driver side behind the dash...right behind the the light swith. The easiest access that i have found is to take the dash off that covers the light switch and extends over to the radio area. Also the lower coverings will need to be removed as well. Once those are off, the TCCM can be accessed. It has three connectors (two large blue and one small black). disconnect the connectors and remove the unit. Note: once you have disconnected the connectors you will notice one of the large connectors is grey(middle connector), make sure it goes back into the proper place when reinstalling. If you are replacing the TCCM with a new one, you will have to get it reprogramed. This whole process shouldn't take more than 1 1/2 - 2 hrs. start to finish
