The steering switch may not be working properly. You can replaced the switch or you can test the values at the switch:

Values at the G/Y wire at the ASCD steering switch with the ignition switch 'ON'

ASCD steering switch is “OFF”. Approximately 4.0V

CRUISE switch is “ON”. Approximately 0V

CANCEL switch is “ON”. Approximately 1V

COAST/SET switch is “ON”. Approximately 2V

ACCEL/RES switch is “ON”. Approximately 3V
