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 the position that the transfer case is in, by monitoring the 4 encoder channels, A, B, C, and P. These inputs translate into 2HI, 4HI, and 4LO, or whether the motor is still in transition between gears.
