u The tolerance of the sensor resistance is °±3%.
u Measure the resistance value of the sensor after leaving it for more than 3 minutes (delay is required due to sensing
speed.)
u Always use a digital tester. Analog testers have a higher margin of error.
u For left and right sensor of lid and drawer, measure both sensor ends of the connector after separating the connectors of
CON 2, 3, 4, 5, CON101 of PWB (PCB) assembly and main part. For the outside sensor, measure end of 2 and 5 of
CON101.
