Genesis COUPE BK 2010, Manual

Page: 80 / 168

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 4th gear
ratio, while the transaxle is engaged in the 5th gear. For example, if the output speed is 1,000 rpm and the 5th gear ratio is
0.840, then the input speed is 840 rpm.
This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the 5th gear
ratio, while the transaxle is engaged in 5th gear. This malfunction is mainly caused by mechanical troubles such as control
valve sticking or solenoid valve malfuctioning rather than an electrical issue.
