STEP 1. Perform voltage measurement at door mirror assembly (LH) (incorporating blind spot warning light) connector.
(1) Disconnect the door mirror assembly (LH) connector, and measure at the wiring harness side.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Check the voltage between the door mirror assembly (LH) connector terminal of AN1 line and body ground.(1) When the actuator test (Item No. 1) is executed.OK: 6 volts or more
(2) When the actuator test (Item No. 1) is aborted.OK: 1 volt or less
Is the check result normal?
