In today's video we take a look at a 2013 Ford Edge w/ 4 cylinder 2.0l Ecoboost engine. According to the repair shop the vehicle has been sitting for about 2 years with a bad transmission. The shop recently replaced the transmission and test drove the vehicle. The next day when the customer came to pick up the truck, it would'nt start! They scanned the vehicle and found the PCM was not communicating. After checking the grounds and connections, they decided to call me to take a look. Follow along as I take you step by step through troubleshooting a bad PCM.

Great video thank you for posting that. I would assume that after replacing a PCM even if it is pre-programmed, the vehicle would need a perimeter reset.

@ADVANCEDLEVELAUTO 2 жыл бұрын

That is correct. I forgot to mention this. The shop had a capable scan tool for that.

@fredsalter1915 2 жыл бұрын

What is a perimeter reset?

@josephgronkiewicz328 2 жыл бұрын

The body control module has the key code and hit that the PCM needs in order to start the vehicle. The perimeter reset basically syncs the PCM to the body control module for the key coding.

Excellent video. Ultimately had to replace the PCM in my 2008 Explorer Sport Trac. For dealer had the car, and they were unable to get a PCM from Atlanta, so I found one in Jacksonville, FL, and it too, came pre-programmed from the rebuilder. The dealer was surprised that I could find one, and they were happy to install it. Worked like a charm.

One of the most painful and valuable lessons I've learned while doing electrical troubleshooting in my career was because of voltmeters and led test lights! Now I usually use my test light that I installed a fog light bulb in that pulls like 4 amps if I'm testing power supply or ground circuits and it has never failed me!

17:44 a headlamp bulb drawing 15 amps is kinda off there. 15 amps @ 12v = 180 watts, regular headlamp bulb (499/477/H7) would be almost 4.6 amps @12v (55w) but yea I would totally be checking those main grounds with a high current test lamp especially if they carry the current to ground the injectors and/or ignition coils but if it's just a sensor ground then yes a low amp incandescent test light is suitable but each to their own, obviously everything else looked to a bad computer (which it was), I've been burnt by assuming a low amp test light (~200mA) lighting a ground before calling it good but under a 'normal running load' it was bad causing stalling but again in the video this was a KOEO no comm requiring very little draw

Great video! I like the idea of testing for shorts to ground in the reference circuits that way but I always got told never to do that because going from battery positive with a test light to a reference circuit could spike the module by putting 12 to a 5V outlet, I guess it all depends on the internal circuit board design really

Substitute the 5v ref with your own thru your PP3 with the 5v adapter and it then should restore communication.

@windward2818 Жыл бұрын

In the BCM block diagram the PCM wake up is active high (pulled to 12VDC), and the representation is given as a "FET" which is very generic and the transistor symbol is even generic, neither IEEE symbol for a JFET or a MOSFET. Which is okay because in reality the part used will be a smart power high side driver, which is a very sophisticated part having more circuitry than just a FET, which will have ease of control from the Microcontroller but also output protection and diagnostics. The important point is there is not a single component like in the diagram, but a smart protected driver. If it was a FET like a P-Channel MOSFET which would work but is not protected, the terminals would be labeled Gate, Drain and Source. In modern PCM design you could have a protected 5VREF and still have CAN communication. So, the 5VREF could be shorted to ground, for example, but the CAN communication would still be able to function. The two functions, VREF and HSCAN are actually two separate systems, VREF is part of the analog section used in conjunction with SIGRTN, and HSCAN is part of the digital communication section. I think the PCM only needs IGN power to wake up normally. The BCM signal wake up is for keyless entry operational options (remote start) where the PCM wake up is needed in order to support the special function. Missing all three 5V references means that the engine module power supply is not working. But, what is strange is the PCM power relay is activated. So, this must mean that this relay control is outside of the Microcontroller strategy. Which makes sense in that the relay is controlled by IGN or Wake Up. For the 5VREF short to ground test you could use the newer Power Probe with the 5V load test adaptor, or you could use a current limited regulated power supply set to 5V DC at a current limit at 1 Amp which is better than a test light to 12V. It is better because the test is within the normal voltage level of 5V DC.
