Transfer Case Encoder

The encoder is mounted to the transfer case encoder motor assembly and is replaced only as an assembly. The encoder converts the sector shaft position into electrical signal inputs to the transfer case shift control module. The module detects what position the transfer case is in by monitoring the 4 encoder channels, which are P, A, B, and C. These inputs translate into 2HI, 4HI, and 4LO or whether the motor is still in transition between gears.
