4. Test and Replace TCM (if necessary)

• Using a multimeter, check the voltage at the TCM connector to ensure proper input/output signals.
• If the TCM is faulty, carefully remove it by unscrewing any mounting bolts and disconnecting the wiring harness.
• Install the new TCM by connecting the wiring harness and securing it with bolts.
  • Tools Required: Socket set, multimeter.

5. Reconnect Battery and Clear Codes
