Awesome video, I'm a locksmith by trade, the red light in the cluster top right is the security light, it is supposed to turn off if you have full communication and the security system is up to par. Solid light means fault in computer system, flashing light means key problem.

[@bradharpin7159]

Yessir about to say that flashing red is not good

[@bradharpin7159]

I mean solid I had that problem and it was pcm

[@codywichman213]

i know it ended up being a pcm issue. and just alittle tip for the future. ive been burned on these older dodges, the asd relay has a power feed that goes to the pcm and also the alternator. I had a van that had repeat pcm failures. We all know about chrysler pcm problems. but still, either way the asd relay is controlled by the pcm, and supplies power to the fuel pump, injectors, sometimes the trans relay, and the alternator. The pcm also uses that power in its wake up process. So what im trying to say is dont forget to check the asd power supply to the pcm, ive seen where the driver in the pcm fails not turning on the asd, and ive also seen where the alternator has a partial short in the field circuit causing a 5-10amp draw on that power feed..which usually melts the circuit board. It can cause repeat pcm failures, and be overlooked until the alternator finally fails completely. Just wanted to throw that in. Great job on the diag, its always nice to see a tech that understands how to LOAD test a power and ground. Fewer and fewer people understand this basic concept, i love the power probe but i still use my test light to double check also. What ever shop couldnt fix this, obviously cant be bothered to check for a crank signal at the starter before replacing it. Thats crazy

I'm just a backyard mechanic who works on my own cars. I find your videos super interesting and educational. Thanks a million.

[@WoodLox]

Phenomenal job tackling a diagnostic issue. Whoever changed the starter was obviously not experienced, starter relay jump would of cranked. I’ve been diagnosing cars just off sheer knowledge and process of elimination, voltmeter and a light tester. Now we have great scan tools and the power probe to assist the main tool, your wisdom and experience. Again excellent job.

[@toyotafan1234]

On these older Chrysler vehicles you can hold down the trip button on the cluster and turn the key to the run position. It will do a check and all the gauge needles will do a sweep

Nicely done brother. Always enjoy watching another diagnostic technicians process.

[@alejandroespinoza3686]

He forgot the MAP sensor. The red light at the top right corner went off with the new ECU. Awesome video, thank you.

[@mikechiodetti4482]

Yup. Definitely an instrument cluster problem! Only other test I would have checked to see if the scan tool had shown RPM. That way you have a record that the PCM is sending the information to the IPC which shows the tach is bad. Other than that, very good diagnosis, good call on the PCM and overall, very good fix Eric!

I like your honest approach to attempt to find the problem with the rpm gauge. I also try to anticipate a customers request when informing them of additional issues. On my part, at least I will have an idea for a potential repair and cost. Thoroughness. An admirable quality. Also as you mentioned , customers don't always inform us of additional problems hoping everything will be solved when we make the repair. They just want it fixed. Love your content and approach.

As for the trim over the gage , it would dry and crack from the sunlight. You could move the light bulb board like he did on the video.

Great video as always! It was thorough and right to the point. Where I work, many electricians never bother to look at the schematics when troubleshooting a circuit. They just change parts until it gets fixed or not. My Dad being an Old School diesel mechanic always told me “One has to be smarter than the tool” Meaning, use the tools and manuals accordingly and they will guide you to the root cause.

20:40, that solid red dot on the top right corner lit and went away after a few seconds, so that must be the security light lol. Good call on the computer and the checks on the possible shorted sensors bringing the computer down, that's an extra step that most techs may ignore to save time but could be a costly misdiagnosis.

[@Dark_Knight_USA]

Greetings: About the same tests I would run. I saw the teach right away prior the sweep test. I figured defective. The PCM is no surprise. Mopar junk notorious 4 that. I have heard they have a programmed software time bomb. However it is not time based, it is mileage. Good show mate.

Dude great content very educational and truly professional. HONEST AND SMART MECANIC.

[@markcondrey2297]

You are spot on with your procedures and your diagnosis. However in my experience with these pcm parts, 90% of the time they are repairable. On the main power inputs there are 5 watt general purpose rectifier diodes that are sacrificial in nature. They protect the pcm from voltage spikes and they will either short or open . I suspect that the unit you diagnosed in your video had open power clamp rectifier diodes. When they open ... You have a dead pcm. They are simple to solder in and out and you can buy a bag of 20 for about $8. When they short ... The damage can mover further into the pcm and can damage the EPROM. When the EPROM is damaged I generally replace the pcm. Generally it is harder to open the pcm then is to repair them, and having said all of this, you can save a lot of time and money just doing a check on these rectifiers.

[@W.Khairi]

Very cool, Any idea how can we identify those rectifier diodes?

[@markcondrey2297]

@@W.Khairi Yes they are easy to find. Usually near the wiring harness plug in port. 5 watt diodes are easy to identify, and generally easy to solder. Inside the ECU there will be a buck power supply sending tightly regulated current and voltage to the logic I. C.'s Google 5 watt diodes and look at the examples. When replacing them be very sure which end the small silver band is on, and insert the replacement part with the band facing the same direction. That is critical. These diodes are easy to check with a standard volt ohm meter. Some even offer a diode check function.

[@W.Khairi]

Great diagnosis. Isolated ECM with problem, checked base power supplies, checked ignition present, all feeds checked with test lamp to simulate load, checked 5Volt output connected and disconnected at sensors. Maybe 5V ref wire short, checked for ground with test lamp no short to ground. Why did it go who knows old age, some one shorted it or reversed polarity it and not telling.

reminds me of an intermittent issue I had with a 96 grand caravan years ago. Crank, run for 1-2 seconds, then die. In frustration I beat on the dash top and got it going, then drove 100+ miles home. Was ok for a week then did it again.... fixed the same way. Finally did it again 100 miles from home about a month later and a shop said there was a can-buss error, but it started every time so took it home. Researched that error and every post talked about dash cluster issues. My son had a similar car with dash warning light issues, and mentioned a post where guys talked about poor solder joints within the cluster. Apparently, the error was causing the anti-theft to kill the fuel pump. I put the dash on the bench and manually went over every solder joint. Never had another problem. Had the car another 7 years after that and finally junked it at 23 years old for other problems. (mostly rust)
