Absolutely sucking the money out. Especially when they don't even know what a PEM is and call the Pump Electric Module the Polymer Electrolytic Membrane .... like the membrane their missing in the brain HaHaHaHa ... Good stuff Ivan the Incredible!!
Ivan IS the man! And from what I've seen nothing will stop him. IMO he's a genius,pure and simple. I've not seen anything electronic/electric stump him. He seems to be at the top of his game.
Volvo fuel pressure sensor is on the driver's side of the fuel rail. High pressure code is because you're running the pump at full-load with your jumper which results in max pressure (too high for idling/light load). One tip for avoiding battery drain on those Volvos is to switch headlights to parking lights as the current draw is much lower than the headlights/DRL function of headlights. XeMoDeX makes re-engineered electronic modules for Volvos that address common issues.
It's odd how anything got into that module, but time often wins :-( It didn't look too clever a unit did it, and i bet that other shop would have ripped the owner off really well :-(. You are a really nice man ivan, i hope you never give up on helping people, honesty is a hard path to follow.
Pine Hollow Auto Diagnostics I know that feeling as i used to repair electronics for people that could not afford a shop doing the job, or were told it was impossible to fix. "Impossible" was a red flag to me, i had to repair it lol.
quality diagnosis...Just a thought on the volvo lights...When im working on them and need the ignition on i turn the light switch to side lights/parking lights...stops the headlights coming on most models ive found. Keep up the good work...Off now to watch pt3
I got confused when we saw the signal at 20:24. When you checked in part 1, we didn't see any signal/pulse. At first, I thought you fixed it! Thanks Ivan!
Great diagnostic! Looks like that module is some kind of pulse amplifier, It works amplifying the current and voltage signal coming from the ECU/ECM to the fuel pump, by judging the internal IC's in it it looks like it does not need any programming. I am just guessing but looks like those Mosfets are burned. I am amazed about the huge amount of PIDS coming out of this old Volvo ECM and also surprised that your old DS708 is able to read them! I guess Mr Kilmer is right about the DS708... fuel rail pressure sensor and fuel temp sensor! Wow! Also I think you're getting a high fuel pressure reading because you're operating the pump directly out of power source in a constant Max out duty cycle.
Brother I feel you. I'm having the same problem. Do the same thing, take very good care of my car. Been running great, no issues. Then ran out of gas and havent been able to get it started. Got fuel, good cranking Power and alls I can get out of it is crank, crank and crank, but no start
Hey Ivan jus a thought, maybe to see the duty cycle from the PCM when you have the circuit jumped, you could use a 10k resistor on that yellow wire to battery positive which should bring the voltage high on that line. Then use the scope on it to see if the activity from the PCM
Proton exchange membrane electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes
I would assume the reason for the fuel pressure value fault is that you bypassed all of the usual regulatory systems, causing the pump to pressurize the system continuously regardless of demand which resulted in excess pressure. I'm guessing this isn't a disaster since you only drove it a few hundred feet into the shop.
When your power went out it reminded me of a question I,ve had since a lot of the scanners are going wireless. Does you're Verus pro get its power from the vehicle while using the wireless dongle? Or does it needs a good internal battery or separate 12 V source to operate. I like the way you always try to fix an expensive modual to save your customer money! Wish you were closer to me. It would be great to have you 're expertise here in the north west.
Another top of the line diagnosing video great job one question what was the indicator at the end of video 2 that told you that it didn't have to be reprogrammed?
A rear facing 3rd seat only in a Volvo? Nope! My mom's 1979 Chevy Impala station wagon had a rear facing 3rd seat. Went on many long trips sitting in that seat as a kid. 😁
Can you explain me if it is grounded by computer (like you said ground side switch) why scope didn't show 12 V or whatever voltage, instead showed zero voltage. If ECU ground this yellov wire wasn't suppose module show voltage when it is disconnected.
If you go to your local Ford dealer you can get same PEM for under $100. last time I needed one. Also, you can get used one, does not need to be programmed, easier to just replace than diagnose. Volvo parts are a total rip off.
@@PineHollowAutoDiagnostics I would have tested those two electrolytic caps, the big orange and the little blue. They dry out and lose capacitance and can short. Could have been a $2 fix! I am amazed that you could jump out the module and hot wire the fuel pump, and the ECM thinks everything is fine. And on a Volvo! What about the headlights that won't go off?
At 2:40 you were stating about adding voltage to the computer signal. To verify if the module was sending voltage to the pump, would you have simply checked for voltage directly to the pump? Moe
the wiring goes from outside connector to the trunk next to the spare tire (as and extension) on the right hand side so you can relocate the P.E.M. (pump electric module)
I got a question I have a volvo s60 t5 2001 in and looking for the location of on Pump module That tank it's a plastic one Can you help me how to find it
Headlight issue go to the dim module and program it in fullflex rather then lowflex you have today. That is your headlight issue. Had the same in my car just had to plug vida into the car and fix it =)
Just a heads up Volvo adds Baro to that fuel pressure pid. I got burned by it had a regulator performance code so I took gauge pressure and compared it to scan data and it was off so I called a sensor. It was actually gauge pressure plus baro on the pid. Actual cause was due to duty cycle request over 45% at idle and needed a fuel pump.
lol some cars are too smart for their own good! At least it tells you in a roundabout way that you need a fuel pump before it REALLY needs a fuel pump :D
Hey boss my buddy have 04 v70 t5 same problem but I couldn’t find the module at all all the wirings are different Is there a way you can tel me if his car comes with it or have to replace the fuel pump ?
I just sent these videos to a friend with a crank no start xc v70 '05 The vehicle will not start if it is below freezing. Above 32° it has been starting fine. If moisture has invaded that module could this be an explanation?
Ivan nowadays when the battery is low all kind of things are going to fail due to the fact that electronics went out of power or to low power. So first thing is to get good battery power.
It looks like it has too many chips to do only that. It's receiving a pulse signal from the ECM, which might communicate pump speed request by pulse width or frequency, and then translate that into PWM at some other frequency or range of pules widths to control the motor. Also here's some power line filtering (the large capacitor and adjacent choke coil).
I thought it was interesting that this uh. fuel system, just changed the volume of delivered fuel by making the pump go faster or slower. Do I have this understood correctly? I like this variable pressure option. Maybe it prolongs fuel pump life?
Shocked it didn't require programming ... but that's probably because it was built before '07. I see Volvo (Ford) stole GM's brainstorm of locating the fuel-pump-controlling magic box UNDER the vehicle, right in the road salt, sand, and water. Brilliant ... 😠 Will be a MUCH cheaper bill than that ripoff dealer, that's for sure! Was well worth the tow to you from VA - your buddy knew that ahead of time. 😊
@@PineHollowAutoDiagnostics Never tried it myself. Actually never tried that function at all as i never had the need, but this case popped up as a great place to use it. I think... I would have to read up on its purposse first though...
That's the one thing about the DS708 that I don't like. To change the units you have to completely back out and go back in, and on some cars, it's pretty slow going in. Every time I want temps in F and/or pressure in psi, I find I later want my MAF in g/s and you can't have both! I just keep my calculator/converter app on my phone handy. I really like my DS708, though. It's the only full scan tool I have right now but it's got the last 2017 update they came out with. I paid a whopping $225 for the tool on Craigslist.
I would seal the unit if possible. This would be great for United radio as they rebuild this stuff. This is a money maker for Volvo.... Exposed modules should be sealed.
Poor Volvo. Try to get recall info on relocating the fuel module inside maybe still valid to get a replacement module and get it relocated for free. also give that Volvo a tune up... And yea that battery is probably trashed but also turn off the headlights put it into parking light as headlights/daylight running lights on Volvo’s draw stupid wattage.

I did a rack in 2009 Scion XB. I dont know what got on it but it corroded a hole right through the cast aluminum case.
Fix your heat pump and the line power goes out! I feel your pain. Must be some after mkt supply for that module - at those prices.
Ivan on many cars, all you need to do is pull the E brake on to turn off the headlights.
Great point. Should have tried that lol
Love me some Ivan.
Ivan great video. Enjoyed the diagnosis!! But I heard that Volvo had a relocation kit for the module. Worth a try to check out?
When the power went out I thought your heat pump blew a fuse.
NOOOOO NOT AGAIN!!! hahaha

Output transistors are toast, there are two big ones on the board and they likely got cooked/shorted with that corrosion floating around in it.

Without doubt the Volvo needs a new battery too in addition to the fuel pump !
