Re: T/M Vehicle System Malfunction Warning

Sat Nov 02, 2019 7:51 pm

I want to thank this forum for leading me to the right answer. Like many posters have already said, my 2015 Nissan Leaf got this error code all of the sudden. The car won't start, the screen went spastic, with the "T/M Vehicle System Malfunction Warning. See dealer." error intermittenly showing.

After reading this forum's experiences, I concluded that the battery was the most likely issue.

Thankfully the car was in my garage at the start of the weekend, so I didn't need to tow to a dealer. I went to Costco, brought in my old battery, purchased a new one for $82 (which included the $15 core fee / recycling fee, and taxes), and changed out the battery myself. It worked! I'm grateful that this all happened on a weekend and at home, and for the guidance this forum game.

Thanks, everyone.

It is now Nov 2019, so the 12V battery was ~4-5 years old
Total cost: $82
Total time: 3 hours, including initial diagnosis using a multi-meter to measure the battery voltage and confirming that it was at 11V, taking out the old battery, going to Costco, coming home, and swapping out the battery

Great news and sounds like you garage the car which will help prevent the battery from suffering thru temperature extremes. Take my advice; make sure this battery lasts. During the Winter months, I put my battery on a charger for a few hours "every so often" (the plan was every two weeks but... ) on my days off. I usually spend at least 2 hours online before doing anything unless I have something planned out of town.

I started doing this when I noticed my battery would be as low as 12.1 volts even when I was driving 25,000 miles a year. So Nissan's method of maintaining good 12 volt health was not working. Now I will admit having only leased, I have had no battery issues OR old batteries but I still see a lot of instances of dead batteries in cars well under 3 years of age.

Thank you DaveinOlyWA and everyone else above! Problem solved!!!


Like many posters, my 2013 Nissan Leaf got this error code all of the sudden: "T/M Vehicle System Malfunction Warning. See dealer." The car would turn on as if I had not pressed down on the brake (wouldn't drive, but radio, etc. worked) and the brake pedal actually felt like it had retreated so that trying to turn the car on felt atypical and was actually not possible. Basically I was stuck in our garage and on the edge of calling to tow it to the dealer.


Based on the posts above, I hoped it was just a 12v battery issue. I watched a simple YouTube clip on switching out the battery here:
https://www.youtube.com/watch?v=oymqG1xqpUI
You can cut to about 4:40 - 8:10 for the actual instructive install.

I took the 12v battery out. Took it to Costco (just like Dave above) and for $82.67 had a new replacement battery in hand (Costco keeps the old one). I installed the new battery and everything is all fixed and working!!! Yippee!

From first reading this forum to a fixed car was about 1.5 hours total (7:00pm - 8:30pm, including driving to and from a Costco in our other car) and $82.67, and I know almost nothing about working on a car, car batteries, or anything else mechanical. If I can do it, so can you. ;)

Based on some other reading, the 12v batteries last about 5 years or so. The new one I purchased says it has a 3 year warranty. The original battery in my 2013 Leaf was going on 7 years old, so it all kinda makes sense in the end.

Thanks, everyone!

JohnnyRockstar - I just now had the exact same thing happen. Fortunately, I decided to look up and read this thread. So instead of a tow to the dealer and pay them to diagnose and put in an overpriced battery plus their labor, I did a quick trip to the auto parts store and am back up and running just fine.

BTW - my original battery made it 6.5 years before it needed to be replaced.

Thanks guys for putting lots of useful tips in here. :)

I wish Nissan had engineered something into the car to let us know the battery is getting bad and should be replaced. Having it go without any warning and leave you stranded is really not cool. I'm not an engineer, but I can't see that as that hard to put in. Instead it stops running and puts up an inaccurate message that attempts to fool you into going to the dealer and throwing money at them. :x

I'm just glad it happened at home and we were able to take a different car until I could sort it out. It easily could have happened at much worse places and times.

Beyond 5 years - assuming no run-dead events to shorten life, and at least two water top-offs - you are gambling with an old accessory battery. It's like gambling that the timing belt in a non-interference engine won't break years and many miles after the recommended replacement interval. There should be a list of things to replace even if they haven't failed at 5 years:

* Accessory battery

* Tires

* Brake fluid

* Wiper blades.

Very true. On a regular car, you usually get 1, maybe 2 starts where you get a warning about the battery going before it won't start. But on these, you don't. So adding battery replacement to the maintenance schedule at the 4 or 5 year mark would be good to do - would really help with reliability and reduce the risk. Going forward, I think I will adopt that on any modern car as so much is dependent on those batteries.

^ great advice. I'd add the key-fob battery. That one does give you a warning and I'm getting it intermittently now after 2.5 years. I'm surprised it is so low already since I never use the key fob buttons to open the doors. I guess it must still transmit to open the doors and start the car but I never push the buttons on it, at least not intentionally.

I'm not sure I've ever heard of one lasting for 5 years, but sure, why not?

The key fob transmits all on it's own. That's how the car knows if the key fob is in the car or not. Pushing the buttons activates certain functions but the key fob sends out a signal all the time. That's why you can leave the fob in your pocket when you start the car.
