Transmission Internal Mode Switch Logic

Circuit/System Description

The automatic transmission manual shift shaft position switch assembly, also called the internal mode switch (IMS) assembly, is a dual sliding

contact switch attached to the control valve body within the transmission. The 9 outputs from the switch indicate which position is selected by the

transmission manual shaft. Four outputs (A, B, C, P) are range selection inputs to the transmission control module (TCM). Five outputs (R1, R2,

D1, D2, S) are direction selection inputs to the hybrid powertrain control module (HPCM). The input voltage at the modules is high when the
