Top 20 2002 Toyota Prius Questions & Answers

Pull up the error codes.

Error Code: P3030 Description: Disconnection between battery and ECU. The battery ECU monitors a voltage of the battery blocks to detect an open malfunction in internal battery voltage sensor circuits of the battery ECU and the wire harness between each battery block and battery ECU. If a voltage at one of the battery blocks is below a standard level or of all the battery blocks is within a specified range, the battery ECU judges that there is an open in the internal sensor circuit(s) or wire harness. The battery ECU then illuminates the MIL and sets a DTC (Diagnostic Trouble Code). Trouble Area: - Junction Block Assembly (Bus Bar Module). - Frame wire number 2, (Bus Bar and wire harness). - Battery ECU.

you've probably burt out the coil, there is enough in it to start briefly but not stay running, start there.

Get the car be scanned thoroughly to locate the problem.

Hello, the first thing I would recommend that you buy a repair manual that shows step by step instructions, with illustrations I can't do that here. You'll need some common metric tools and a voltmeter, there are high voltages involved and you will need to wear insulated gloves rated at least to 1000 volts DC to prevent severe injury or possibly death. The actual replacement is not that difficult: Disconnect the 12 volt auxiliary battery disconnect the orange service plug on the hybrid battery and tape the connector on the battery remove the rear seat and the seat back braces remove the trunk carpet and the spare tire cover remove the two orange cables going to the front measure dc voltage at the terminals where the cables were removed there must be less than 1 volt. remove the 12 mm bolts that connect the battery to the body including the torx bolt slide the battery back and have someone help to lift it out.

The Prius come woth a custom built Li-ion battery and there is no way that you can replace it by yourself. It is better to contact the Service centre to get it done. They will get you the original battery and also complete the replacement within a day. The battery is located in a T-shape structure beneath the driver seat and through the middle of the passenger section.

Check the fuel level sensor.

its a prius. take it in, lost of things to go wrong with any hybrid, due to huge complexity. if serious DIY, and feel compelled to get shocked on HV? then read the FSM buy it ran read all the pages on 3000 and on how not to get shocked and killed. do so , dont guess study the book. or go there, first google hit for 3000, read this ? http://priuschat.com/threads/code-p3000.49355/ could it not just be, that you didnt follow the battery swap instructions in the FSM then trip these/ reset them and see if they come back. P3004 - Power Cable Malfunction 130 HV Battery Malfunction. When HV battery voltage becomes lower than inverter voltage 131 Power Cable Malfunction. When main fuse is blown out, service plug is disconnected or limiter resistance is cut off 133 HV Battery Malfunction. When inverter voltage sensor is malfunctioning or limiter resistance value increases

sound like end of life for display or bad connection at its connector. wiggle connector to it and pray.

a FIAT TOYOTA, is this and engines swap? is this diesel,?what year?, what injection systems?, what country/ what displacement/, is it turbo,.,, ? we can not guess this. ever. strike 6, im out.

Does it shake at low speeds or high speeds? yr make model??? Was the wheel balanced when put on the vehicle? You need to give complete details Please.

does jumper cable starts work off a donor running car/truck. using the glove box operators guide telling you HOW TO DO IT safely?????

where which one. lost the operators guide>? in the glove box. here is the generic list http://dashboardsymbols.com/the-symbols/

Chances are that you are experiencing the same problem as me. If it is a loud humming sound, the rear bearings are worn out. I haven't repaired mine yet, but I have new bearing hubs and hope to get it repaired next week, Hope this helps. Does yours have high mileage? Mine has 154,000.

which lights, head lights?, did you look in both fuse boxes?

Hello, first check the auxiliary battery in the trunk, if it's more than 4 years old it most likely needs to be replaced, this is a very common problem, if it's not the battery you'll need someone read the trouble codes in the computer, most autoparts stores do this at no charge.

Here's a link to the fusible links,check and see if they are good.It's next to the battery,here's another link to the wiring.Look at engine control,enlarge.

The light that looks like a car with an exclamation mark in the middle of it is the HYBRID WARNING light (see diagram below) You must scn the onboard computer network to determine why this light is coming on. You also need to scan your computer system to find out why the engine keeps dying. If the hybrid batteries are discharged, they must be properly recharged to prevent serious damage.CAUTION: Read ALL service and warning lables in the engine compartment before attempting ANY type of service on a hybrid vehicle. The wiring harnesses that have ORANGE connectors are HIGH VOLTAGE connectors and can cause serious injury or death.DO NOT touch any wiring harness or component that has a HIGH VOLTAGE warning label on it.My recommendation is to tow the vehicle to a qualified hybrid repair center (preferably the dealer) and get it properly diagnosed and repaired. The high-tech, high voltage systems in this vehicle is nothing for anyone but a trained, certified technician to be messing with.

Answer: Its a prius and you should feel bad
