Measuring Resistance

WARNING: This page is about a different car, the 2018 Kia Optima. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the cruise control switch connector from the control switch.

Measure resistance between terminals on the control switch when each function switch is ON (switch is depressed).

Function switch	Terminal (A Connector)	Resistance (kΩ) [± 5%]
CANCEL	2 - 5	0.18
SET -	2 - 5	0.33
RES +	2 - 5	0.55
CRUISE	2 - 5	0.88
ASCC	2 - 5	2.54

If not within specification, replace switch.
