Typical Scan Tool Data
Circuit/System Description
The manual shift detent lever with shaft position switch assembly, or internal mode switch (IMS) assembly is a sliding contact switch attached to
the manual shift detent lever within the transmission. The 4 inputs to the transmission control module (TCM) from the switch indicate which
position is selected by the transmission manual shaft. The input voltage at the TCM is high when the switch is open and low when the switch is
closed to ground. The state of each input is displayed on the scan tool as IMS A/B/C/P. The IMS input parameters represented are transmission
range signal A, Signal B, signal C, and signal P.
