2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Switch Condition	Specified Condition
   1 - 2 1 - 3	Cruise control switch off	1 MΩ or higher
   1 - 3	Cruise control switch on	Below 2.5 Ω
   1 - 2	MODE	Below 2.5 Ω
   1 - 3	+/RES	235 to 245 Ω
   1 - 3	-/SET	617 to 643 Ω
   1 - 3	CANCEL	1509 to 1571 Ω

3. Reinstall the cruise control switch. Refer to INSTALLATION [08/2012 - ] .
