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.
