dead battery
will the Yaris ECM throw a code if the alternator is bad?? I am getting just a battery icon on the dash.... The battery was completely dead while driving...It just barely made it in the drive.It was dying at the last 2 traffic lights but kept running barely..This happened fast. AN hour before I didnt notice anything. Then the radio quit but oddly the XM radio kept going but no sound. The battery was a red Top Optima about 2-3 years old. I checked the fuse for ALT ok... any ideas??

No - No code will be thrown for a bad alternator.
To start, measure the battery voltage with the engine off and with it running.

I had a similar problem with my OEM battery ... drove it Saturday and it was fine and on Monday it was totally dead. I had no advanced notice .. no dash lights nothing. Replaced the battery ... and it is fine again.

Odd, my battery has been on its last legs for a few weeks now. Tough starting on cold mornings, but as the day warms up it's fine! I keep meaning to replace it, before it strands me somewhere (I do have jumper cables in the hatch).
Cheers! M2

I finally had to connect an external booster pack to the battery to keep the car running ... and drove that way to the Toyota dealer. So .. I would recommend getting a new battery before it is too late. I didn't expect to get stranded either but I did. |

This is was happened to me too. When my alternator is out, I had no sign at all. After I park my vehicle that's it. At first I thought was the battery. I jump start it and drove in a block the vehicle dead again. I jump start it and once I pull the jump cable out the vehicle is shuts down. Finally know is the alternator. Check the voltage and it gotta be 13.9 with vehicle on. When the vehicle is off is 12.8. Good luck!

IT was the Alternator.Luckily this town has a small starter rebuilding service. A rare thing nowadays.
Usually they say just replace it. Anyway the mechanic had it tested(bad) and rebuilt in a few hours. He said the brushes were non existent, they were so worn. But not bad for 350K. eh? Now I have a shiny new looking little powerplant with all new guts and a 14v read on the ScanGauge. The Optima red top is good and my little charger cranked it good all night. It was interesting to see that the car had no problems driving the 20 miles to the shop on a charge. I didnt use any accessories.I didnt think it would make it. Good to know.100 bucks for a like new alternator plus they installed for a bit more. |
