2.Measure the resistance between terminal No.1 and terminal No.2 when each of the ACC distance switches is pressed. Measure the resistance between terminal No.3 and terminal No.4 when each of the speed limiter ON/OFF, cruise control ON/OFF, CANCEL, SET -
and RES +
switches is pressed. If the values measured at the time each switch is pressed correspond to those in the table below, the resistance values are correct.
