Have you ever had the tccm reprogramed? Maybe as a last resort before you replace it would be to have it reprogramed if there are any updates.

Did you disconnect the battery before the install, also check your ATC fuse under the hood, it could have blown. Last i would check for a bad ground or connection.

Removal Procedure 1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information. 2. Remove the transfer case shield. Refer to Transfer Case Shield Replacement . 3. Remove the front propeller shaft. Refer to Propeller Shaft Replacement - Front in Propeller Shaft. 4. Remove the motor/encoder electrical connectors. 5. Remove the motor/encoder mounting bolts. 6. Remove the motor/encoder assembly. 7. Remove the motor/encoder gasket. Installation Procedure Important o If the motor/encoder assembly is being replaced because it is defective, make sure that the transfer case is in the neutral position.

Install the NEW motor/encoder gasket to the transfer case. 2. Install the motor/encoder to the transfer case. Notice. Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. 3. Install motor/encoder mounting bolts. Tighten Tighten the bolts, in the sequence shown above, to 20 N·m (15 lb ft). 4. Install the motor/encoder electrical connector. Ensure that the retention clips activate. 5.
