Question about Toyota Yaris

OBD plug not working

I was trying to jump start my Yaris in the dark and briefly hooked up the cables to the wrong terminals. I quickly corrected the problem and everything seems to be working fine except for the OBD port next to the hood release. I had a Progressive Snapshot Discount device hooked up which stopped working afterward. I requested a replacement device which also did not work. This makes me think there is something wrong with the obd plug not the device.

That plug has its own fuse. Please consult the fuse box diagram for the location and size.

SOURCE: location of OBD-ll on 2011 Lexus is250

US law dictates that the ODB port be located within easy reach of the driver. It is most likely just under the dash at the very end of the dash board. There will not be any panel or cover for this port. It will be easily found if you look under the dash.

Where is the 100amp fuse for the alternator

Middle fuse in the fuseholder attached to the positive terminal of the battery. It is probably a blue fuse and the cap is marked ALT 100A

Usually blows because someone attached the cables the wrong way round trying to jump start (which is easy to do on the side of a country road in the dark when it's raining) or else put in a new battery and got the terminals the wrong way around (which is pretty hard to do).

Let us know if you find it. If you put a new one in and it blows again, you may have an alternator problem so don't try it again before sorting that out (may even need an alternator).

How can i close the sunroof on a 2002 chevy

check the 25 A breaker (PWR WDO) in fuse block I/P
if the driver power window is working your breaker is ok
check terminal B of the connector 2( pink wire) of the sunroof control module for 12 volts. check terminal D connector 2 of the sunroof control module(black wire) for a good ground. If the sunroof does not work with the switch you could jumper the power to the motor. You could try jumping terminal B to terminal A ( dark green wire) and jumping terminal D to terminal C (dark blue). If the sunroof goes the wrong way, change terminal B to terminal C and terminal D to terminal A. If it doesnot work the motor is dead.

How do I jump start my car

You can use a jump box or another car. Using another car while running hook the red cable of the jumper cables to the positive battery terminals on each car. Hook the black cable to the negative battery terminals on each car. Now try and start the car with the dead battery.

Hi, I have a 2008 Pontiac G5 and I accidentally kept the lights on all day. Since I only have a positive (red) connection, I ground the negative connection to metal as well as the other car negative...

sounds like you are on the right track. Hook the jumper cables up to the dead car first. The red cable should go to the jumper terminal as you mentioned and a good place to hook up the black cable is the bolts on the strut tower.

then with the other car running hook up the red lead to the cars positive battery cable and then the negative to a good ground. Let the two cars sit for about 5 to ten minutes to give the dead battery a chance to charge.

Once the dead car is started let it idle with the lights turned off for at least 45 minute to an hour or drive it for the same amount of time with the light on (I assume you will be driving in the dark) or if its day time drive it for 30 to 40 minutes with the lights off. This should be enough time for the alternator to charge the dead battery.

How do I jump the battery?

Hook up the red cable wire to the positive terminal on the battery of the car to be jumped, then hook up the other red jumper cable wire to the jumper vehicles red or positive terminal, it is recomended on the car to be jumped that you attach the negative cable to a metal bracket on the motor or body that can be attached securely (good connection), then attach the other last cable to the negative battery terminal, if you cannot find a suitable bracket to attache the negative cable to use the negative battery terminal. When doing all this try to keep the two ends of the cables seperated from each other, always wear safety glasses when working on auto batteries the can explode if a spark or flame gets too close to the top of the battery.

'98 Wrangler, cleaned battery cables, flashers blink won't start

From your post, it seems that you may have only cleaned the outside of the terminals. The engine was cranking... this tells me that 'though cleaning the terminals is a good maintenence item, you did not have a problem there. Remove the cables and clean the inside of the wire terminals and the battery contacts. This will put you back where it would crank, but not start. (make sure the battery is fully charged while you are there)
After you can crank the engine, check for spark at plug wires, fuel supply etc. Problems there will begin to tell you where to proceed!
Good luck!
