Monitor Description

WARNING: This page is about a different variant/trim than selected.

The ECM commands gear shifts by turning the solenoid valves on and off. According to the input shaft revolution (speed) and output shaft revolution (speed), the ECM detects the actual gear (1st, 2nd, 3rd, 4th, 5th, 6th, 7th or 8th gear). When the gear commanded by the ECM and the actual gear are not the same, the ECM illuminates the MIL and stores a DTC.
