Check your hybrid drive coolant reservoir for coolant level. top off if needed using only Toyota coolant. Also common for the auxiliary water pump to fail. I think there is a recall free replacement. Check with your dealer if your car is included in recall.

Don't reset the battery, as it will only remove the error code but does not fix the problem. You may want to locate a store that can
check obd 1 (1995 and older).

Check under drivers door sill step. There is a spice I believe the wires are red or pink in color. The splice will be wrapped in black hockey tape looking stuff. Peel the the hockey tape stuff off and you will find that this splice is corroded and not making contact anymore. You can repair this splice and your problems will be fixed. Be sure to use some good heat shrink on your repair to prevent from happening again.

Why is my Check Engine/Malfunction indicator light on? ecm.jpg The engine computer or ECMAll modern vehicles have a computer or the ECM (Electronic Control Module) that controls the operation of the vehicle powertrain (the engine and transmission). The main purpose of this is to keep the engine running at top efficiency with the lowest possible emissions. With constantly growing demands for better fuel economy and new strictest emission regulations it's not very easy to achieve. The engine parameters need to be constantly and precisely adjusted according to various conditions such as speed, load, engine temperature, gasoline quality, ambient air temperature, road conditions, etc. That's why today's cars have much more electronics than in early days - there is a large number of various sensors and other electronic devices that help the vehicle computer or ECM to precisely control the engine and transmission operation and monitor emissions.
The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.

You must have the dealer scan the engine control system module for fault codes, one or more is set whenever the light is turned on. This should be covered under the emission system warranty for 7/70,000.

My 2008 prius abs and brake light came on and the the brakes became very hard and constant beep noise, so how to fix it as its really irritating continuous noise beep.


The ABS system is in need of immediate service. The hard pedal is the ABS/Hydraulics malfunctioning and beeping to let you know. Could be a sensor or module maybe a wiring/connection issue but have it serviced ASAP . A bad vacuum supply to the booster or booster diaphragm can also cause a hard pedal and any could light the warning light.

I have a red triangle with ! inside it and red car with ! in the middle of it , so please i want to know this error in Toyota Prius 2008


This the hybrid master warning light, which means the system has detected a malfunction, there are many causes that turn the light on, there are about 24 computers involved, the best advise I can come up with is that you have the toyota dealer check this and diagnose it, this may also still be under the powertrain or hybrid vehicle warranty

How to link iphone4 via blue tooth to a 2008 prius


It's not possible to obtain stereo Bluetooth for the 2008 Prius. Toyota did not make this possible until the 2010 model with the navigation package. Actually, if your iPhone 4 is jailbroken, there is a complicated way to trick the car into thinking your music is actually a phone call, and it will force play the music over the speakers as such. But the quality is terrible (mono, not stereo). You're much better off sticking to the AUX cable, even though it does get annoying to plug in every time you drive.

Malfunction indicator lamp in my toyota corolla is on how i fix?


The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

Warning lights


On a Prius, when the check engine light comes on it indicates a malfunction in the powertrain control system. You need to have the car scanned for codes to see where the fault lies. The red triangle lights because the check engine light is on. The VSC is disabled when the check engine light is on and that light comes on.
Start with having the car scanned.
