   RESISTANCE REFERENCE CHART
   
   

   Function switch	Terminal	Resistance
   Cruise Main	RH 1-2	3.9kΩ ± 5%
   Cancel	RH 1-3	0Ω ± 5%
   Set/Coast	RH 1-3	220Ω ± 5%
   Resume/Accel	RH 1-3	910Ω ± 5%

3. If not within specification, replace switch.

MEASURING VOLTAGE 

1. Connect the cruise control switch connector to the control switch.
