Another IMRC module repair - tricky this time

Trying to fix another Ford IMRC (Intake Manifold Runner Control valve) module. This time it's not so easy. A tricky situation when it doesn't work, yet all components appear good.
UPDATE: It was reinstalled and it worked, so either the lubrication or resoldering the questionable solder joints helped.

so refreshing to see real repair and analysis instead of videos that just blindly replace every electrolytic cap.

This is what you do when there are no electrolytic capacitors in the circuit.

I also can't stand people who just replace all caps and give up if that does not instantly solve the problem. However, I see electrolytic caps as wear parts, limited by hours and with an expiration date, similar to a timing belt. So I first properly find the issue and do the repair, and if the device is valuable and older than 5-8 years, I then blindly replace EVERY electrolytic with high quality ones before reassembling to prevent future issues. It might be a waste of capacitors, as 95% of them are maybe still ok, but I don't want the other 5% failing shortly after and causing trouble. In my oppinion, replacing old caps is part of maintenance. I also do the same with timing belts on cars: If I buy a car and can't 100% confirm the belt has been changed recently, I just replace it, even if it means lowering the entire engine to change it. I would rather lower an engine to replace a 2 week old belt that just has no documentation to prove it is new than remove and rebuild/replace the engine because I was lied to, and the belt was actually 10 years old and snapped on the highway.

Awesome video! I love to see someone testing all components looking for the faulty component and explaining everything instead of looking for the dead component before recording and then just recording the replacement of the component that caused the failure. Nice job! Keep up the good work!

thanks for this teardown ، you can download the datasheet of the LM1949 and try to give it a 12v power supply and a PWM to the input voltage at Vin its a simple circuit. also u can verify with scope that the ECU send pwm signal to the controler .

how come LM1949 is a fuel injector controller? and used here to drive a motor?

Ford IMRC bushings are around $10 each. Replace all four of them. The brand HELP sells a 4 pack of them for $8. Perhaps you can find the brand Help in Helpa? Say hi to my family there!

I love the diversity of electronics assessed on your channel. Frustrating to have "magic" repair, when we all want precise reason for fault, but mechanical movement and heat/cold are technically valid repairs too I suppose. I would not be able to resist using data sheet of the IC to test pins while powered on. Thank you for posting.

I found a diode in a plasma tv that was reading as a diode both ways. So i always check them both ways round now

@ritosankhohalder9366 10 ай бұрын

Once, I found a bridge rectifier made of discrete diodes, and when I tested the diodes, 3 of them were reading as diodes in both ways. I do not know how the IC was still alive.

@reacey 8 ай бұрын

Just thought id add that this diode was reading both ways out of circuit, and was the cause of the tv not turning on

@teardowndan5364 10 ай бұрын

WD40 or other similarly thin oils are more for cleaning than lubricating, pretty much all of it will just drip off. For gears like these that have no oil pump to bring the oil back where it is needed, you need something somewhat tacky like lithium grease that will stay on the gears without the viscosity getting in the way too much.

A myth, perfect lubricant for this scenario. See the web side of WD for details of the light lubrication properties..and the myth about non lube!

The problem is probably in some control unit. I had similar problem with simpler door lock motor unit of a last generation Escort, I checked it - nothing wrong after which I bought a new motor unit, and the problem remained - it appeared the control unit did not work out the signal for the locked position, given by simple sliding contacts.

small voltage variation in the emitter circuit provokes higher voltage variation in the collector circuit- hence you get voltage gain despite no current gain

True but he knows, you have to constantly be thinking how can this test be wrong, he covers this by explaining the diode and resistor in the Darlington that kills the hfe and the cap across the motor that'll look short, with this method it's all about getting lucky, when you don't have schematics to test properly meaning powered up, it's a very common youtube method and only works for absolute dead parts not partially failing or intermittent or incorrect dc bias ect

YUK. Crappy Ford electronics. Drive the motor to the end stop then keep wasting current and heating the motor by holding it against the return spring. What's wrong with a bridge circuit so you can drive the motor both directions? I guess so if the system fails, the throttle goes to minimum.
