Unplug ATCM, located inside glove compartment. Measure resistance between terminals No. 10 (Dark Green/White wire) and No. 26 (Black/White wire) at wiring harness connector. See Fig 1 . If resistance is not 145-175 ohms, replace lock cylinder sensor, or repair circuits No. 936 (Dark Green/White wire) and/or No. 397 (Black/White wire). See WIRING DIAGRAMS .
