  2. Measure the resistance between the supply voltage circuit terminal 1 and the signal circuit terminal 5. Individually activate and hold each cruise control function switch and compare the resistance reading to the values for the On, Off, SET - and RES + switches.
    • If any of the resistance measurements for the On, Off, SET - and RES + switches are not within the listed resistance values, replace the multifunction switch.
