- Cruise Control Combination Switch - Test
1. Measure the resistance between cruise control combination switch 12P connector terminals No. 2 and No. 5 according to the table. If there is no resistance in one or more positions, replace the cruise control combination switch. Position Resistance OFF About 2.2 kΩ CRUISE (PRESSED) About 60 Ω CANCEL (PRESSED) About 190 Ω SET- (PRESSED) About 450 Ω RES+ (PRESSED) About 900 Ω 2. Check the LED for illumination when connecting battery power and ground to the switch terminals according to the table. NOTE: this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse). If the results are not as specified, replace the cruise control combination switch.
