What should battery voltage be in Toyota Sienna?
First thing I would check is the alternator. With the engine off, see what the voltage is on the battery terminals. It should be a little above 12 V. Then turn the engine on and running, check the voltage again. It should be a little over 13 V, but under 14 V.
Why does my Toyota Sienna battery keep draining?
That is consistent with a parasitic load, since even 20 minutes is enough charging to get the battery up to a reasonable level (with a sound charging system), and the stopped time during the day is not enough for the parasitic load to be a problem.
Can you turn off the interior lights in a Toyota Sienna?
It ONLY works under a VERY NARROW set of circumstances, and even then it ONLY works for the 2 overhead map lights in the FRONT ROW ONLY. In reality, it is NOT something most owners can rely upon as a “safety net” to help them remember to turn off the interior lights.
Are there any recalls on the Toyota Sienna?
AFAIK (this is based on my memory of discussions at the old site), the JBL-problem/recall was for 2005 Siennas “only”…..and only a limited production range were affected. For 2004 & reportedly some 2005s, the “battery-saver” feature does not work how most reasonable people would think it should work.
What to do if your Toyota Sienna battery goes dead?
When any of the map lights are turned on manually (with the courtesy light switch in the door position) and left on, they will NEVER go off by themselves (until the battery goes dead). The “battery saver” only turns the interior lights off if a door is left ajar, that is the part that didn’t work on the 2004 and early 2005 models.
Can a Toyota Sienna go for a weekend?
Now the problem is so severe the van cannot go a weekend before the battery is drained. First happened a month ago when the van sat for two days. This weekend, the van was driven was on a Friday night, sat in the snowstorm Saturday and Sunday, and Sunday night the van couldn’t turn over.
What’s the parasitic draw on a Toyota Sienna?
Draw started off at about 350mA, after about 30 seconds drops to just above 200mA, and after another minute or two it drops down to just above 10mA. So, my problem is thankfully not a parasitic draw but was a bad battery, which Costco swapped out. Lucky I caught it at 35 months.
How does an alternator affect the charging system?
The alternator is at the heart of the charging system of your vehicle. Alternator problems and charging system problems can affect your vehicle in different ways. You may notice: your ALT or CHARGE indicator light comes on, your engine is hard to start and cranks slowly, or doesn’t crank, your battery demands lots of water,
What should I do if my Toyota Sienna battery drains?
Battery always can recharge itself after I run the van for 1/2 hour. I tested the current drain last night between the cable and the negative terminal when the car was turned off: 0.001 Amps. Any suggestions? i would take the battery back for a replacement.
