That's not the correct part number. The correct part number is 31651-TZ5-A02 for the 2017-2019 Ridgeline and 31651-TZ5-A03 for the 2020-2022 Ridgeline.
Battery Fan responsible for AWD and Charging System Warning Lights?
New to the club so apologies if I've missed the answer to my question within another post. 2017 sport built 11/16. VIN 18928 so not specifically in harness recall. Out of the blue the charging system and AWD lights came on. AWD definitely not working but no issues discernible with charging system (I've had alternators go bad so I know what that looks like). And I've been driving it for the last few days without problems. Took to dealer today and was told the battery fan failed and it's the root cause of both. Anybody heard of that?

Thanks for your response!Sorry I am late replying to your post, but listen... I have had two RLs since 2005. Minus a break for about 2 years between Gen 1 & Gen 2, that's 14 years. Zero issues other than a back seat plastic cam failure and a RF headlight that burned out after about 5 years. Seriously, other than oils and a timing belt (that I pushed to 11 years vs 7/9 on Gen 1), I have had nothing go wrong. And even the timing belt is a known wear item.
Yes, it sucks when you have issues, but it's real life. Mechanical things fail. If only I could help people understand HOW MANY brand new, off-the-shelf parts failures I have seen in my short life...
I am an electrician by trade and I do know what you're talking about. This isn't the only problem I have had with this truck. I wouldn't say I have a lemon but not the quality I expected either. only 60K miles on it at that. I had 2 different Toyotas (not trucks) and had nothing but breaks and tires over 5 years with 150k plus miles on them. I was kind of expecting that from Honda.

Had this problem intermittently over the past 3 months. It would disappear when I turned the vehicle off and not appear again for months. Yesterday the messages came back and have remained on. I ordered the battery fan. My question is there any problem driving the vehicle while waiting for the replacement part?
Nope, just swap it when you get it.
The docs say that the battery sensor checks battery liquid temperature. How the heck does it do that?
There is no battery temperature sensor. The vehicle estimates the temperature of the battery using other data from other sensors such as the ambient temperature sensor.
For my 2018 Ridgeline RTE I ordered the battery fan part 31651-TZ5-A02 and they sent me 31651-TZ5-A03..... will that fan work in my vehicle?
@zroger73, you are a national treasure sir!
I climbed into my truck a few days ago and received these codes. Truck has 120,000km on it. Honda Canada says the part is backordered. They want $183.36 for the part and $59.98 for labor to install it.

Well, that depends on who you ask. To some, I'm a wart on the face of society.@zroger73, you are a national treasure sir!

Glad you got your issue diagnosed and hopefully the part arrives sooner rather than later.
Sorry for the late reply. I replaced my battery fan and no more error codes (for last 10 weeks).. YEAH!!!
The process took about 15 minutes and then an additional 1hr to try and retrieve the 10mm wrench I dropped into the engine abyss.

Hi, Ridgeline EXL 2017, with 45000km, now out of warranty. Got the AWD and charge system warning from a week now. suspected after 5 years of battery condition, test 12,5v and with alternator charging at 14,5 v.
Local Honda dealer doesn't have the fan of battery case in stock, promising in July...
Did remove battery case and small blower fan and cleaned it. This little fan assembly does have some internal surface mount pcboard electronic parts and showed corrosion.
since I'm in electronics repair used some contact/lube cleaner. small fan does spins fine, but corrosion in there is not so good...
Suspected also fan connector, cleaned, re-assemble everything, still i have AWD, Charge warnings on dash and now battery warning too.
Battery volts ok at 12,4v and charging at 14,5v
So i asked dealer parts to order the fan blower. Tech says there is no recall on this, and says it's not a part the is often needed or sold !?
Will wait for the part and now i know how to dismantle and re assemble the thing.
Thanks to this forum, i should resolve this issue.

Hey so have a 17 just got 108000 on it. The other night these same warning lights came on. Confused hooked up the scanner and did some digging. Found nothing that made sense. I wanted to change out the original battery before winter this year so figured I would start there. When I had the box out I noticed this fan. So I found this thread I bench tested the fan and it did not work and was shorted to ground. Had power going to it in the harness and harness had ground so assumed that was good. Noticed that when the fan was unplugged the lights went off on there own and all went back to normal while it was a cold ambient air temp at least. I was sure this fan was junk. So I ordered the fan installed it and all was perfect. Thanks just had to share this. The part that threw me off was the charging system warning was on but the battery light was not.
Now since two days warnings are gone!?
Seems the contacts and cleaning did some good. Still weather here was warm.
Got the replacement fan blower on order until it arrives.
Just hope I don't get any other stupid sensors, bad connectors.

Problem is gone, hot weather here, so it looks like gone.
Talked with Honda mechanics, didn't know that issue, or seen it??
He is informed now hopefully.

Hi fellas
Don't own a ridgeline but a mdx 17
When I was browsing for "charging system problem" light found this thread
Got a quick question
When you have both warning does your steering wheels function are fully working?
Please advise

Have the exact same issue wth my 2017 Ridgeline. Honda dealership have confirmed it's the battery cooling fan (after a $300 diagnostic session!). Replacement part is $500 CDN + labour! Brutal....but apparently no way around it...too many sensors/electronics these days!!New to the club so apologies if I've missed the answer to my question within another post. 2017 sport built 11/16. VIN 18928 so not specifically in harness recall. Out of the blue the charging system and AWD lights came on. AWD definitely not working but no issues discernible with charging system (I've had alternators go bad so I know what that looks like). And I've been driving it for the last few days without problems. Took to dealer today and was told the battery fan failed and it's the root cause of both. Anybody heard of that?
That fan is a $50 part and a 10 minute job. Dealer is a thief.
Same happened to my 2017 over this Christmas. Never knew battery had a separate fan. The way the battery is enclosed makes hard for air to circulate without a fan. Anyone know of a way to by pass all the plastic around the battery or maybe tried something. Dealer says there’s no way, but that’s what I’d expect from a dealer.New to the club so apologies if I've missed the answer to my question within another post. 2017 sport built 11/16.
