ACC Combination Switch - Test
1.
Measure the resistance between the ACC combination switch 12P connector (male terminals) terminals No. 5 and No. 6 according to the table.
If there is no resistance in one or more positions, replace the ACC combination switch.
Position
Resistance
OFF (Released)
About 2.2 k?
MAIN (Pressed and held)
About 60 ?
CANCEL (Pressed and held)
About 190 ?
SET - (Pressed and held)
About 450 ?
RES + (Pressed and held)
About 900 ?
2.
Measure the resistance between the ACC combination switch 12P connector (male terminals) terminals No. 5 and No. 12 according to the table.
If there is no resistance in one or more positions, replace the ACC combination switch.
Position
Resistance
OFF (Released)
About 2.2 k?
DISTANCE (Pressed and held)

3.
Check the LED for illumination when connecting battery power and ground to the switch terminals according to the table.
NOTE: 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 ACC combination switch.
