Crossfire Can't CRANK? (Part 2 - No Comm with TCM-ESP-Shifter)

In Part 2 we address why the TCM, ABS, and Shifter Assembly are all offline.
This is a great example where some detailed wiring diagram research pays off big time!
After narrowing down the issue, the next question is how to REPAIR it?
Any Parts Required?
Or maybe we can engineer a more reliable solution ;)
But the Crazy Crossfire might have more surprises up its sleeve...

Part 3?!? The gift that keeps on giving, eh?

[@johnleinen7167]

Good job Ivan! As a Mercedes tech we dealt with these 20 years ago ,that car is a rebodied 170 SLK chassis and they had so many issues, we called those a K40 relay. Powers everything, crank sensors were a high failure part on these V6 and V8.

[@99domini99]

Yep haha! I guessed it last video, and my guess was right! Those K40’s go bad so often it’s usually the first thing to look at for a crank-no-start and offline modules/no power. They’re pretty easy to fix, it’s almost always a bad solder joint. A bad connection inside is often the cause of intermittent no-start and stalls.

[@mohammedgani7583]

And give us five minutes and I'll be absolutely thank you

[@ehsnils]

In some cases it's the end wire of the relay coil that has failed because it was improperly bonded to the post. A magnifying glass inspection could be useful just to check that.

[@PineHollowAutoDiagnostics]

Much appreciated, thank you 🙏

[@jamesanderson2176]

I'm a little concerned about joining those circuits. This would've been a perfect opportunity for them to cost-reduce that box, so there must have been a reason why they chose to include an additional relay.

[@Kehvelii]

True. The cost reduction may also come from not having to manufacture a different box for cars which need separate feeds and for cars which don't.

[@michaelslee4336]

@@Kehvelii My vehicle had manual window winders but all the wiring was up to all the doors and up to the window controller switch next to the driver. It must have been easier and/or cheaper just to run the same loom for all the cars on the production line.

[@killer2600]

It would be my guess is the extra current is needed when the traction control activates during a traction loss event. Definitely a concerning repair.

[@PineHollowAutoDiagnostics]

@@killer2600 if all those modules are on one 15A fuse, then normal power consumption is well below that, which one relay should easily handle 😉

[@Malc180s]

I guess that particular relay is borderline for that current draw. It'll probably be fine.

[@housemaster509]

On the working relay the fuses are after the relay, on the not working relay the fuse is before the relay. If you join the relay outputs, the output is not secured by a 15A fuse (only by the 40A fuse).

[@brainndamage]

Still, just put in a 15A fuse with some wires poking out of the case. There's no need for those two relays to be separate.

[@housemaster509]

@@brainndamage I think the manufacturer had something in mind, when they installed two relays instead of one. Perhaps they wanted to make sure, that one module could not power the other modules backwards, when the relays were not activated.

[@Knight_of_NI]

Coffee and a Pine Hollow video, it's gonna be a good day!!!

[@lvsqcsl]

Did you use "battery negative" instead of "battery positive" during your test of the relay Ivan? Did you make a mistake? WOW! I don't ever get to see that! I hope in part 3 you don't need to find a relay board for that car. These videos that contain component repair are VERY interesting. GREAT VIDEO!

[@wallebo]

I love that you show the "my bads" in your videos. It gives hope to the rest of us. In my case, however, there is no hope but I would imagine that you can get my sentiment. Rock on, Ivan! Great video.

[@sabrekat7904]

nice bit of investigation/analysis to get to the failed component and a good cheap fix for the customer.Appreciate that the load on that working relay is minimal,however,it has switched just as many times as the failed relay and now it's workload has doubled.You may have already done this but I think I would have suggested to the customer to start saving now for either a new module or to look for a good used module as a precautionary move.Assume he is keeping the car of course.

[@stealthg35infiniti94]

Brilliant Repair! I can easily see why people will bring their vehicles from 10 hours away.

[@gianfrancoa]

Hey Ivan, this is a known issue with the Mercedes R170 platform. At one point or another this K40 relays fails. The previous owner replaced already on my SLK320. You can still find these new. The issue is that the ECM relay will also fail and leave the car stranded. Regarding the ABS light, you have to turn the wheels lock to lock to relearn the steering wheel angle

[@rhkips]

I'm guessing the ESP kicking in on wheel spin overloaded the ECM relay circuit you had piggybacked off of, and either borked the jumper wire, or the fuse, or there's actually an issue with the ESP system causing it to pull to much current, which is what stressed the circuit in the first place and caused the initial customer complaint. Eagerly awaiting part 3 to see! :D

The original failure was of the relay coil, not the contacts. Therefore the fault was not the result of an overload.

[@paulmoffat9306]

Just about all electronics today, are soldered with Lead free alloys (almost pure Tin) and those do not flow and 'wet' a joint as well, unless lots of flux is used. Also, Tin has the annoying property of forming dendrite growths that can bridge and short connections - really troublesome with dense packed micros. A good flux that I use in repairs, is M.G. Chemicals 'No Clean' Rosin Flux #835-50ml. No Clean means that removing excess from the board is not necessary, but Brake Cleaner, Lacquer Thinner, or Isopropol Alcohol all work well doing that.

[@RussellBooth1977]

That's a bit like when I was diagnosing my great uncles stepdaughters 1997 model Ford EL Falcon (Australian made car) which had a stalling problem, whenever I diagnosed the problem it would resurface later down the track. It wasn't until it was towed to my dads place because it ended up being undriveable that I finally nailed the problem,it was just a non standard engine immobilizer/car alarm which was the culprit. The Fix was to rewire it back to how Ford had the ignition switch wired up at the factory meaning totally bypass an engine immobilizer which had been wired up in series with the ignition switch for about 1/4 of a century . So the problem was something else & other than I thought it was !

[@Dcs-Brasil]

Good solution

[@rodneymiddleton9624]

I replaced a failed ignition lock on one and had to cut it off because it wouldn’t turn to the service position. It was a terrible job and the parts were in the $1400.00 range. The ignition cylinder had to be special ordered for the original key and car. I don’t envy you Ivan!

[@PineHollowAutoDiagnostics]

[@michaelschmidt7014]

Ivan I love your troubleshooting and repairs with the exception of 'jumpering out relays' or othe components. I reserve the 'jumpering activity' for components that I find are not available due to obsolescence by the manufacturer or not availabe from previously owned or junk yard sources. One of the things I find annoying is a previous tech does a field repair in a not so very well condition causing longer troubleshooting to determine just what was done and why. For this repair yours is a great field repair. If the owner was agreeable I would have tried for a relay replacement . As of this posting there are several OEM relay packs not the same P/N but same internal OEM relays on Ebay. Further I also saw some NEW individual relays from our not so favorite place China (BARF) I am not a fan of Chinese quality I have had too many failures and poor customer service on previous repairs. In either case great repair on your part keep up the good work.

[@publicmail2]

There was probably a reason why the 2 circuits had separate load/relays, bridging the 2 doesn't sound right to me, that would mean the load sides mix, even though they always both are on with the same control side. Also, you may greatly exceed the relays ampacity.

[@brainndamage]

Probably not, why would there be multiple power feeds to the same circuit? It isn't shown in the diagram. Other than still needing to add the 15A fuse, it's a viable repair.

[@chiluco2000]

Most likely it's an overly engineer German part. Seems they should have: - simplify the design by using one relay - make that relay serviceable and not soldered to the board
