System Check For Normal Operation
- Turn ignition to RUN position and shift selector to PARK position. Place mirror ON-OFF switch to ON position or OFF-MIN-MAX switch to MAX position. Cover ambient photocell sensor (windshield side) with a dark cloth. Shine a flashlight onto headlight photocell sensor (mirror side). If inside rear view mirror and left outside mirror (if equipped) gradually darken, go to next step. If mirror(s) do not darken, check connections. If connections are okay, check Pink wire and/or Pink/Black wire circuit between mirror ON-OFF switch and fuse block for an open or a short to ground. Check Black wire or Black/White ground circuit for an open. See WIRING DIAGRAMS .
- Do not remove dark cloth and flashlight. Move shift selector to REVERSE position. If mirror(s) gradually lightens to a clear state, go to step 4). If outside mirror does not lighten, go to next step. If mirror(s) does not lighten, check connections. If connections are okay, check park/neutral position switch operation. If park/neutral position switch is okay, check Light Green wire circuit between inside mirror and Park/Neutral position switch. If Light Green wire circuit is okay, check Pink wire circuit between park/neutral position switch and fuse block.
- If electrochromic outside mirror (if equipped, RPO code DD0) did not change, check Gray wire and Pink wire circuits between inside mirror and outside mirror.
- Do not remove dark cloth and flashlight. Place shift selector to PARK position. Mirror(s) should gradually darken. Remove dark cloth and flashlight. Mirror(s) should gradually lighten to a clear state. If mirror(s) change as described, system is operating normally. If mirror(s) do not change as described and fuses, connections and circuits are okay, replace suspect mirror assembly and retest system.
