ctric vehicle) Mode" of your 2004+ Prius. In Japan and European versions of the Toyota Prius the vehicle is sold with an EV Button pre-installed by Toyota. For some reason, in the North American version this button is left off (note: speculation focuses on possible EPA/NHTSB regulations that were unclear as to whether the option to use 2 different 'fuels' was legal. Also it has been speculated that the decision came from Toyota, but no clear statement, at this writing, has come from Toyota. The EV button MAY become a dealer option or as a standard feature on future model year Priuses). However, the HV ECU is programmed for the EV button. Accessing this feature is a basically simple procedure. One simply needs to plug a wire into the proper plug on the ECU, attach that wire and a ground wire to a momentary switch and EV mode is available. Unfortunately, accessing the proper pin to plug the wire into the ECU plug, accessing the ECU and threading the wire and finding a ground are a bit tricky. These instructions are designed to take you step by step through the procedure. Download free 2004 Prius EV (Electric Vehicle) Button Installation Instructions pdf here

Installing the Cyron HT-1506 LED footwell light kit in a Toyota Prius

This guide was written by a Prius owner who is neither a photographer nor a graphic artist. This will become obvious as you read this document. It is assumed that if you are going to attempt this installation that you are familiar with auto mechanical systems, auto electrical systems, and basic tools. This guide is meant to be informative but cannot be guaranteed to be complete nor to represent what is found in your vehicle. The author disclaims any liability or responsibility for anything that happens to your vehicle as a result of following these instructions, including damage to your vehicle, personal injury, emotional distress, paper cuts, and anything else I may have forgotten. Bottom line: Please use good common sense and don’t sue me if anything goes wrong!

The purpose of this guide is to assist in the installation of the Cyron HT-1506 background LED lighting kit in a Toyota Prius. The Cyron light kit is available at Costco for around $50 or online from Ebay or Cyron. The pictures are from a 2005 and 2008 Toyota Prius. The Cyron HT-1506 uses 3 primary color LED’s (Red, Green, and Blue) to generate solid and mixed colors and can be set to scan through the pre-programmed color ranges or stopped at one particular color. Some have tied the kit to the 12v accessory outlet so that it comes on whenever the car is powered up. I chose to tie my kit into the car’s dome light circuit so that it comes on when the dome lights illuminate and turns off about 10 seconds or less after the dome lights extinguish. Both methods are described in this guide. I have also installed a manual override switch that allows me to turn the light on whenever I want, even if the car is not powered on. I based my design on what I have read about the Toyota OEM footwell lighting kit. I have never used or disassembled the Toyota kit, and my circuit design is based on the description of how it works and what I know about the operation of the dome light control circuit as published in the Toyota wiring manual for the Prius. I would guess Toyota’s design is similar if not the same. Download free Installing the Cyron HT-1506 LED footwell light kit in a Toyota Prius pdf here

Toyota Hybrid System Diagnosis HV Battery Control Systems

Posted by Auto Repair Manual 0 komentar
The principal role of the hybrid battery system is to monitor the condition of the HV battery assembly through the use of the battery ECU. That information is then transmitted to the HV Control ECU. The battery ECU calculates the SOC (State of Charge) of the HV battery based on voltage, current and temperature. It then sends the results to the HV Control ECU. As a result, the proper charge and discharge control is performed.

This system also controls the battery blower motor controller in order to maintain a proper temperature at the HV battery assembly. To do this while the vehicle is being driven, the battery ECU determines and controls the operating mode of the battery blower assembly in accordance with the temperature of the HV battery assembly.

ALWAYS wear high-voltage insulated gloves when diagnosing the Hybrid System. Check your gloves before wearing! Even a tiny pinhole can be dangerous, as electricity will find its' way in. To check your gloves, blow air into each glove, hold the glove tight like a balloon and make sure no air escapes.

Careless handling of this hybrid system may result in electrocution or electrical leakage. When servicing the hybrid system strictly follow the instructions found in the Repair Manual. In the HV battery pack, six nickel metal hydride type 1.2V cells are connected in series to form one module. In the '01-03 Prius, 38 modules are divided into two holders and connected in series. Thus, the HV battery contains a total of 228 cells and has a rated voltage of 273.6V. In the '04 and later Prius, 28 modules are connected for a rated voltage of 201.6V. The cells are now connected in two places, reducing the internal resistance of the battery. Download free Toyota Hybrid System Diagnosis HV Battery Control Systems pdf here

Stereo Accessory Installation Guide 2004 Toyota Prius

The following guide describes how to disassemble the dashboard of the 2004 Toyota Prius in order to remove the stereo to install aftermarket accessories. It is geared towards installing a Neo CD-changer to RCA (aka line-in) adapter, although what you install after disassembling the dash is up to you (see pg 11 for a discussion of various options). It was based on disassembling a Prius without a factory CD changer or tape deck, though I would guess that the process wouldn’t change much if either of those components were installed. It was written by an average Prius owner who has no formal electrical or automotive maintenance training, so use at your own risk.

Disclaimer: The author of this document and anyone who distributes it do not warrant or assume any legal liability or responsibility for the accuracy, completeness, or usefulness of any information, apparatus, product, or process disclosed. Any disassembly of or modifications made to your vehicle using this guide are done at your own risk and are not recommended or endorsed by the author of this document or its distributors. Such disassembly or modifications may damage your vehicle, void its warranty, or cause personal injury.

With those warnings in mind, I have disassembled my dash twice without damage to my vehicle, and I have done my best to make this guide as clear and easy to follow as possible. I would normally recommend disconnecting a car’s battery before exposing its internal workings, but I do not know if it is possible to disconnect the Prius’s huge battery array, or if trying to do so could cause damage to the car. My battery remained connected during my two dashboard disassemblies. Download free Stereo Accessory Installation Guide 2004 Toyota Prius pdf here
