ACC Combination Switch Removal, Installation, and Test: Test
- ACC Combination Switch - Test
ACC Combination Switch Internal Resistance Check:
1. Measure the resistance between the ACC combination switch 12P connector (male terminals) terminals No. 9 and No. 11 according to the table.
Position Resistance at normal ambient temperature OFF (Released) 2.0-2.4 kΩ MAIN (Pressed and held) 54.3-66.3 ' CANCEL (Pressed and held) 165.0-201.7 ' SET - (Pressed and held) 401.7-491.0 ' RES + (Pressed and held) 802.7-981.1 ' If there is no resistance in one or more positions, replace the ACC combination switch.
2. Measure the resistance between the ACC combination switch 12P connector (male terminals) terminals No. 8 and No. 11 according to the table.
Position Resistance at normal ambient temperature OFF (Released) 2.0-2.4 kΩ DISTANCE (Pressed and held) 401.7-491.0 ' LKAS(Pressed and held) 54.3-66.3 ' If there is no resistance in one or more positions, replace the ACC combination switch.
ACC Combination Switch Illumination Circuit Check:
1. Check the LED for illumination by applying power and ground to the terminals according to the table.
NOTE: 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 ACC combination switch.
