Transmission Control Module (Tcm) - Suzuki Ignis Service Manual

TRANSMISSION CONTROL MODULE (TCM)

TCM is an electronic circuit component that controls gear shift, idle-up according to the signal from each sensor.
Also it has learning control function for performing optimum control. It is a microcomputer consisting of an IC,
transistor, diode, etc. It is installed behind glove box.
