Dealer Couldn't fix it...for 5 YEARS!! (Nissan No-Start when COLD)

My neighbor has been having a cold-start issue with his 2011 Suzuki Equator (Nissan Frontier) for the last 5 years.
He says whenever it's below 20F (-5C) outside, it just cranks and does not fire up.
He has taken it to the Nissan Dealer for the last 5 winters and spent over a GRAND on diagnostics, and his truck is still broken!
Let's see if we can 100% pinpoint the root cause of the no-start and get this truck back to full health.

[@peteh1942]

As an electronic technician the 2 tools for solving this sort of problem was a can of freezer and a soldering iron. Normally this sort of problem was associated with electrolytic capacitors rather than dry joints and when time is money these tools proved invaluable. Love your train of thought on solving problems Ivan.

[@jonmullaly7497]

On board circuits are another profession all together. Caps are not an issue like old days and diag a board is high skilled biz... Most DIY board fixes I've lucked out on are microscopic resistors that short/open. I've done plenty of reflows on clusters and drl modules however...

[@mike_svt93]

The last couple of episodes with follow ups from happy customers is a nice touch closing the video. Good job!

[@Fix_It_Again_Tony]

I wonder if this is a solder joint problem related to lead free solder. We had a problem at work recently where certain boards would grow dendrites between the pads of a very tight pitch connector during the "damp heat" test which was causing system failure during the test. Basically you warm the system up to about 40 °C and keep the humidity high, but not condensing, and hold it there for up to 48 hours. It turns out only boards which needed manual re-work during initial manufacturing had this problem. It was traced back to a problem with the solder flux being used during the re-work process. We changed the flux chemistry and the problem went away. Naturally, we use lead free to be RoHS compliant. I am not saying dendrite growth caused the Nissan problem, but my point is you just need to be careful with your solder process. Something that was never a problem with leaded solder, or with a wider pin pitch, or with a different flux formula, or in different operating conditions can become a problem and take a significant amount of effort to troubleshoot and fix.

[@arcadeuk]

Lead-free solder is the work of the devil, it makes anything subject to high vibration half as reliable. I thought automotive, medical, aerospace and military were exempt from RoHS (for obvious reasons) so has that changed now?

[@Fix_It_Again_Tony]

@@arcadeuk You are right. RoHS does not apply to "means of transport for persons or goods", but there is a end-of-life vehicle (ELV) directive dating back to 1997 which aims to "prevent[] the use of certain heavy metals such as cadmium, lead, mercury and hexavalent chromium". That is technically for the EU, but with a global company like a big automaker there may be reasons to adopt rules like this world wide. It also depends on who actually makes the ECU. Nissan probably has a contract manufacturer design and build this part, someone with a specialization in automotive control units. If whatever company makes them already has lead-free SMD lines then that is what they would build. So maybe the solder isn't lead-free, but I wouldn't be surprised if it is. I work for a German company and they make us jump through hoops to use any part which has an RoHS exemption and if it isn't RoHS compliant at all there is no chance in hell we can put it on a board. I forget sometimes that other industries aren't even covered by RoHS.

[@hightttech]

Almost certainly a solder joint issue. I wonder if the PCB is potted, epoxy coated or just the ECM case is environmentally sealed. Would love to get it on the bench and probe around the PCB with some freeze spray.

[@ScottDLR]

It make the possibility of cold solder joints much more likely for sure.

[@annaplojharova1400]

Automakers (or their suppliers) do use lead free solder for cost reason. Leaded solder requires that line to be completely separated from other production. Plus to handle the leaded stuff, way more complicated material management procedures are required (handling with toxic substances), which adds cost. As the lead free solder technology has somehow matured, most switched to it just to save cost. But I don't think such a temperamental thing as a cracked solder or a whisker short circuit would behave so consistently over the all 5 years. My bet would be more on the use of some inadequate component, whose parameters vary with temperature so the thing fails consistently at the same temperature threshold. Mainly electrolytic capacitors are known to deteriorate their ESR at freezing temperatures. When the electrolyte starts freezing, it stops conducting the current; and in these capacitors one electrode is formed by and so connected via that electrolyte solution. There are of course types using electrolyte formula that does not freezes (at least until -40degC), but there could have been batch with either somehow compromised electrolyte composition (unintentionally more diluted, inadequate mixing,...), or a wrong capacitor type was mixed in. And a capacitor is on the spotlight also because during cold cranking the circuit has to activate voltage boosting to maintain internal voltages even when the battery voltage is sagging. And this boosting may bring higher current load on the capacitors, so when their ESR gets higher, the voltage ripple becomes too high for the computer to operate correctly.

[@Old1Too]

FYI, I ordered an ECM from FS1 back in July 2019 for my Chevy trailblazer. It came programmed with my VIN and works perfectly, no issues.

Great Video as always.. I am a dedicated follower of your channel and appreciate your diagnostic process and your reasoning for going the directions you do. It has been helpful in in my own work. I used Flagship One last week on a Ford PCM and was extremely reluctant after seeing all the bad reviews online. The cost was very reasonable and took 10 days to have it in my hand but everything was programed in as it was supposed to be worked well. Again thanks for the channel and all your hard work on bringing it to us...

[@TheWilber09]

That's awesome the owner took the time to make that little video.

[@MoraFermi]

With regards to the electronics not working in low temperatures, it suggests cracked solder joins. It's likely on some through-hole connection, possibly on the connector itself.

Most company's I've dealt with specifically on electronics components outright tell you that they won't cover warranty specifically on used parts.

Hi Ivan I've been watching a lot of your videos recently , your diagnostic skills are amazing, I've been in the motor trade for 42 years here in the UK 30 of them working on BMW, some of the problems I've watched you diagnose have taught me a thing or two, especially when you get the scope out, I don't think a lot of workshops own a scope or know how to use one, keep up the good work.

[@TonyRule]

I've been out of the trade for a bit over quarter of a century in NZ. We always had an oscilloscope everywhere I worked in NZ, but almost nobody had a clue how to use it except one guy I worked with late in my apprenticeship - he was a mechanic that looked like a nerd so of course HE knew. So I mostly had to teach myself with library books - remember those?. The first one was a gigantic yellow Krypton as part of the "tunescope".

As an engineering electronics technologist dealing with communications I love watching your troubleshooting skills.

So business sense, you don't have the time nor does the customer want to spend the money going down to this component level sleuthing. I am entertained by your videos, thanks.

[@TonyRule]

Yeah, fine to do for the sake of curiosity or for yourself, but not when running a business. But I would like to see a tear down of this one - it's quite possible the fault is obvious. And this is the home of NPR repairs! You really have to admire the quality control when the same parts fail on all the the same vehicles. Many people don't realise that quality control isn't about making the parts work longer or better, but that they're all the same, design faults, poor solder joints and all.

My guess on the problem with the failed module is a faulty uC resonator/crystal. The uC is static (no clock) until the module dissipates a little power warming up the crystal. This would be easy to test if you have access to the circuitry and use some freeze spray to cool down the crystal.

One thing to remember is. Look at the outside temperature on your phone and the ect and iat data on the scan tool. My wife had a 2006 Taurus that had a hard time starting when cold. I used a cheap code reader and the ect read 40 degrees Fahrenheit and so did the IAT sensor. But it was -10 outside here in Buffalo. So I plugged in the snapon modis at the time. Both sensors read -40. Default value. I installed a new coolant temp sensor and the car started up and then stalled. Turn the key and started up and ran perfect. Two throttle snaps and we didn't have a problem with it again. This actually happened in February of 2015. When the northeast was in a deep freeze.

[@HeyBirt]

A cold temperature problem with electronics could be related to a bad solder joint, things shrink and you have a bad connection. It could also be an input or output that goes through an optical isolator. Optical electronics are greatly effected by cold, a photo diode becomes much less sensitive. It could also be an issue of a bad bonding of the leadframe (external pins) to the die (actual ship) inside the IC. You can sometimes localize the problem area of the PCB with freeze spray.

I was thinking along the same idea. One would need a schematic of the unit.

Had a Ford Ranger (2003) that would not start when cold. Long diagnosis period (multiple issues) but what was determined in the end was that the engine coolant sensor was defective and was telling the ECM that the engine was warmed up when it was actually cold. The temperature Guage on the dash was reporting the temperature correctly which fooled us for a while. The problem was detected when live data did not match the dash Guage. Turns out this engine (3 liter) uses two coolant sensors. One sends voltage to the dash Guage (good) and the other supplies voltage to the ECM (defective).

How ironic I have the same issue with my Nissan Pathfinder 2012 every winter or when it starts to get cold, she wouldn’t start. She would crank crank crank, but no start but I followed the little method about a year or two ago, and she would start if she doesn’t. I put another battery to it to give it more of a boost, and she would start, but the Nissan dealer said to bring in the Nissan Pathfinder 2012 there’s a recall on the ECM or ECU. Hopefully they will replace it and hopefully my problem will be solved. This Mechanic is a great mechanic. We need a lot more like him out there. I’m pretty sure there is, he’s very on point with everything he says and explains to you so you can understand how your vehicle should be working.
