Seeking Advice on Possible Terminal 30 Interruption in 2015 Toyota Previa

Hey there, I’ve had a somewhat related experience with my 2013 Toyota Sienna. Similar in nature, the sneaky culprit was a defective battery. On my side, I'd rate myself as having some car experience. Off to my local workshop, it was a pretty simple diagnosis. They ran a battery load test and, well, it turned out my battery was indeed defective. The process set me back around 290€, but hey, no more dimming lights or morning battery blues. As every ride is unique, it would aid in a more accurate diagnosis if you could provide additional info about your heaps. Details like mileage, the health of your alternator and when your battery was last replaced can all play a vital role. Hope this helps, keep us posted!

Hey! Thanks for your input! Your experience sounds kinda similar. As for my Toyota Previa, it's sitting at around 59125 kilometers. The battery was recently replaced a few months back around the time of the last service. The alternator is still original from when I got the car back in 2015, could indeed be a suspect as you pointed out. I'll definitely consider the battery load test and get into a workshop this week. It's really helpful to understand the cost I might be dealing with. I'll keep you all posted on this mystery! Cheers.

Hey back atcha, Really cool that you're being proactive about this. With that mileage and a recent battery replacement, your Previa should still be in decent shape. The alternator being the original could indeed be the culprit. It's worth having checked out, especially given it's been powering the vehicle for six years now. That battery load test could still prove useful, too. It might be that the new battery is faulty, or perhaps it wasn't installed properly - things like this happen. In any case, this test could help pinpoint what's going wrong, truly. As for cost, apart from the battery load test, alternator testing can range anywhere from 50.0 to 100€. If the problem does turn out to be the alternator, a new one plus installation could set you back up to 700€ or more, but hopefully it won't come to that. Can't wait to hear how you get on with this. Brace up, my - you've got this! Keep us posted on what the workshop says, okay? Cheers!

Hey! I really appreciate all those suggestions and the head's up on the costs - that's some solid advice. I agree, the original alternator could indeed be the sinner given it’s up in its years now. And you're right, new batteries can have issues too, even if they've just been installed. I'll definitely have those load and alternator tests done, and I'll make sure they check the battery installation as well. I'll head to the workshop first thing tomorrow, and let's hope it doesn't burn too big a hole in my pocket! Will keep you and the here updated. Won't lie, a bit nervous, but ready to see the back of these problems! Cheers for all the help everyone. I really appreciate it! Have a good one. Stay tuned for the update!
