Before I quit Honda a couple of years ago. Pilots were going into idle stop but were unable to turn back on. Honda, at the time, recommended replacing the battery and performing a valve adjust. Do they still recommend doing the valve adjust in situations like this? As long as the engine has manually adjustable valves, of course.
Honda has come out with a recall for it not restarting back up. It's just a software update and a warranty extension on the starter if after the software update and is still having problem starting up after going into idle stop start. And then doing valve adjustment.
There's a software bulletin out that addresses start/stop issues. Had it done our '17. Start stop kicks in less with OEM battery now. Issue was sometimes the car would stop at idle and not restart. Never experienced that though
It happens to our 2020 MDX. Took it to the axura dealership couple days ago. It says due to the battery thats why it failed the idle stop and needed a new battery. Theyre charging 400+ to replace it. My question is why cant they just recharge the battery if it failed on load? Im just curious why they need to replace the whole new battery and they said u can only replace it with OEM battery not one of those autozone.
For idle stop start to function the state of health of the battery has to be above 70% and that's because when your engine is off it still has to run everything in your vehicle while the engine is off without being charged. Being at 70% doesn't necessarily mean the battery is bad just the computer won't allow it to go into idle stop start because your vehicle is constantly monitoring that battery to be sure that it's able to sustain operation while it isn't being charged and be able to crank the engine back up. While the battery is below 70% state of health it is still technically "good" for normal starting operation. Until 50% thats why they typically last about 2-3 years to 70% or drive it without idle stop. With idle stop start it isn't just a regular load test. You're actually doing a rated capacity test not just a load test as load test are just for starting the vehicle. What you need for idle stop start system is a machine that can do a rated capacity test and what it does is discharges the battery and recharges it back up to see how much capacity it can still hold. And it usually takes over an hr.
I just get the same group size AGM battery from Canadian Tire they have a 5 year warranty. Once it hits around 3 years is when the idle stop start stops working because it hits the 70% state of health. It's free replacement within the 5 years and half the price is what I've suggested for my friends on their Honda/acura. Where Honda /Acura is 1 year free replacement and then it's pro rated.
@@theoffroadingmechanic Thank you brother for taking your time to write this thorough report. I just hate this idle stop BS. I guess you can't just permanently shut off the idle stop. Eventhough, there's a button to temporarily disable it. I've seen people on RU-vid made a by pass for idle stop. You just need to buy that one product from Amazon or something.
Yea I see those it just reverses the switch so when you turn on your vehicle it reverts it to the off setting rather than the on for the idle stop. But here's a video trying to explain this while this company wanted me to test their battery tester. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JqzocYFDw5o.htmlsi=yq_qAtTBzwvBHxDZ
I guess despite it is “good”, the internal resistance of that battery is too high and computer think this is an aging 650CCA battery and disable the function as precaution. I’m not saying it is wrong to design this protection, but modern car do require more compliance on factory spec. 😢 Hey we have the same plastic ramp! 😊
I'd rather keep the higher rated battery ... I hate the stop/start systems .. plus it's gotta give extra wear and tear on everything .... It's a stupid ploy to save 0.00001 mpg
Yea the husband was thinking of leaving it since he doesn't like the start stop and pushes the butten to turn it off every time he starts the car. He knows that it does prematurely wear the starter. But the wife likes the feature so its going to get a battery. Lol
Except when she needs to move immediately, but has to wait until the engine starts. Loosing at least 5 seconds, which could be a matter of life and death.
@@theoffroadingmechanic nevermind the starter, i heard leaving the engine with no lubrication when hot, is a problem? something about destroying rod bearing whatever they are.
After replacing the battery, do I need to input the radio code in order to start the car? Do I need to reset the computer system? Thanks. I’ve tried to start the vehicle after a battery replacement but the brake and the steering wheel are both very stiff and it won’t turn over. The electronic goes wild flashing and lots of short clicking or ticking noise. Anyone familiar with this situation?
The radio code shouldn't have anything to do with the car starting. Are you sure you didn't just put in a bad battery or installed the terminals backwards or if you had tried jump starting it and had jumped it incorrectly.
@@theoffroadingmechanic these tlx are really a pain when it comes to battery. I tested my 3 yr old Acura battery after charging it fully at 12.06 V and yet it didn’t turn over at all. Just now I got a AGM battery and cranked it up…problem fixed. The new battery tested at 12.42V.
the battery still started the car fine just won't go in to idle stop start. Even though it had a much higher CCA it still had enough CCA to start the car.
Seems to me that the newer the car is, the less resilience the electrical systems have. Even using a non-OEM relay or light bulb can cause weird problems
Shoot even something as not programming a battery on a BMW can cause issues. Had a 2014 X1 had several bulbs out, wasn't a bulb issue, check all wires and were intact. Came to the conclusion I had a "faulty" footwell module. Well put a new one in still none of the bulbs worked. Customer had replaced battery and had not programmed it and that's what caused all the bulbs to be out.
@@mikemata623these manufacturers are pure stupid sauce. Why would a battery need to be programmed?! They figure out every way to make current vehicles like thin wet paper smh.
