4. Back-up light switch*2 *1: for Automatic Transmission *2: for Manual Transmission 2. FUNCTION OF COMPONENTS a. The inner rear view mirror assembly controls the system by using information from the following components: COMPONENTS FUNCTION 3. OPERATION EXPLANATION a. The inner rear view mirror assembly receives the R position signal from the park/neutral position switch or back-up light switch when the shift lever is moved to the R position. After receiving the R position signal, the inner rear view mirror displays the rear camera image. 4. NOTES FOR REAR VIEW MONITOR a. Notes for the rear view monitor. 1. The rear view monitor may not function properly if subjected to a severe blow by any hard object. 2. Do not scrub the cover part of the camera (plastic). Scrubbing it may scratch the cover and affect the image. Prevent organic solvents, waxes, bond removing solvents, or glass coating from adhering to the cover. If such material adheres to the cover, clean it off immediately and wash with water. Item Function Television Camera Assembly  Mounted on the tailgate to transmit an image of the area behind the vehicle to the inner rear view mirror assembly.  A color video camera that uses a CCD (Charge Coupled Device) and a wide-angle lens. Inner rear view mirror assembly  Receive video signals, which contain images of the area behind the vehicle, taken with the television camera assembly.  Performs control of the system by receiving the shift position signal from the park/neutral position switch (1) 1 or the back-up light switch (2) .  Displays the rear view monitor image on the inner rear view mirror. Park/Neutral Position Switch (1) 1 Back-Up Light Switch (2) Transmits a reverse shift position signal to the inner rear view mirror assembly. (1) for Automatic Transmission (2) for Manual Transmission 2009 Toyota Tacoma 2009 ACCESSORIES & EQUIPMENT Park Assist / Monitoring - Tacoma Saturday, September 27, 2014 12:39:08 PM Page 4 © 2011 Mitchell Repair Information Company, LLC.

3. Exposing the camera to a sudden temperature change may cause the camera to function improperly. 4. A clear image may not appear if the camera is dirty with snow, mud, etc. In that case, wash it with water and wipe off the lens. Use a detergent to remove dirt if necessary. b. Images are difficult to discern even in normal conditions if: 1. The camera screen is frosted over (the image immediately after turning the ignition switch to ON may be blurred or darker than normal). 2. A strong beam of light, such as a sunbeam or headlight, shines on the camera. 3. The vehicle is in a dark area (at night, etc.). 4. The ambient temperature around the camera is either too high or too low. HINT: When a strong light, such as a sunbeam reflected from another vehicles body, shines on the camera, the image may be blurred. This is called "smear" and is common for the CCD camera. HOW TO PROCEED WITH TROUBLESHOOTING HINT: Use these procedures to troubleshoot the rear view monitor system. 1. VEHICLE BROUGHT TO WORKSHOP 2. CUSTOMER PROBLEM ANALYSIS 3.
