The gear position display in the instrument cluster has twoĭisplays P, R, N, D or S and the second mode displays the manual gear 1, 2, 3,ĬommandShift feature. Illuminating the TCSLED (light emitting diode) 'PRNDS' and the instrumentĬluster displays.
TRANSMISSION CONTROL MODULE DRIVER
The GSM transmits a signal to inform the driver of the selected gear, Located on top of the transmission selector The actuator drives a small connecting shaft which is The GSM selects the requestedĬonditions being correct. 'gear selection' signal transmitted from the TCS. Transmission gear selection in response to the The GSM contains an integrated actuator which automatically controls the
The GSM is mounted on a bracket on the top of the transmission, above the TCM. The TCM uses the neutral position asĪ reference point for each of the gear positions P, R, N, and D. If the TCM, GSM or transmission requires replacement, a setting procedure mustĭiagnostic system to allow the TCM to learn the neutral position of the Rotary actuator which responds to driver selections and rotates the selector Driver selections made on the TCS are passed via CAN messages to the The transmission is controlled by a 'shift by wire' system. Specified voltage relating to the selected TCS The rotary position sensor is a Hall effect sensor which outputs a Selection is made by the driver using the rotary Gear Shift Module (GSM), located above the TCM, rotates the shaft when a The shaft locates in a rotary position sensor and turns the Through an oil seal on the top face of the main The TCM is positioned over the transmission selector shaft which protrudes The TCM uses data from these systems to suspend gear changesĪBS module is controlling braking or traction control.
