Genesis COUPE BK 2010, Manual

Page: 127 / 168

The Automatic Transmission changes the gear position of the transmission utilizing a combination of Clutches and Brakes,
which are controlled by solenoid valves. High&low reverse clutch solenoid valve is controlled by the TCM in response to
signals sent from the inhibitor switch, vehicle speed sensor and accelerator pedal position sensor (throttle position sensor).
Gears will then be shifted to the optimum position.
The PCM/TCM checks the Shift Control Solenoin Valve E control signal by monitoring the feedback signal from the solenoid
valve drive circuit. If an unexpected signal is monitored, (For example, high voltage is detected when low voltage is expected,
or low votage detected when high voltage is expected)
