By the way had the motor replace and the mechanic saw the O2 sensor wires was burnt at the connector onto the wire harness and never told me till after I was told by the muffler shop that they was damaged so that might have shorted out unit took it back they rewired it but I don't think it's wired right burned out the first board then I replace it what the second board so I think the problem is it's not wired correctly and causing major problems told the mechanic shop to replace those wires or check their work I think that's why it's not running now. $700 wasted but they will get it back and fix it or give me back my money and I will go to the dealership. we need more guys like you.

I was wondering if you verified off screen that the computer plugs male and female pins were all making good connections as I didn't see you do that in the video? It's been my experience that the female pins sometimes get checked with the standard DVOM probes by pushing the probe in and opens up the socket a tiny bit. When the male pin plug gets installed, there may now be a loose or intermittent situation.

I use my Jeep then after turning it off, I want to restart it and it would stall after 10 seconds and I would get the "check gauges" and "over heat transmission". I used my computer and it shows "lost communication with ecm/pcm" I checked the wires and had some damaged I repaired them and even put heat resistant tape and protection since they are next to the exhaust. I really don't know 2hat to do at this point. Ant tips would help.

Good afternoon Cody, I checked your awesome video and I followed your testing procedures. I have a 1998 Dodge Ram 1500 5.2. The truck all of the sudden shut down and it just cranks. It’s got fuel but no spark. My cousin started throwing parts at it and replaced the fuel pump, crank position sensor and the ignition rotor. I verified it and indeed has no spark. Has no communication in the DLC. Gauges are pegged to the left and won’t move. I checked the following: -Verified powers to pins 2 & 22 -Verified grounds to pins 31 &32 -Checked the resistance on the ignition coil tested good -Checked the ASD and tested good -Verified 5 volt reference and it was good -Wasn’t able to test pin#30 for the signal coming out (no uscope) -I suspect a bad PCM Any recommendations?

Best to find a shop that can properly diagnose your issue

I’ve had a unlocked pcm and Diablo tuner in my 2017 ram slt for a few months. Did a parameter change one night and. Ow says no ECU detected. Put the key in and everything lights up, stereo comes on, etc. turn the key to start and nothing. No fuel pump, no ignition, nothing. You can hear the relay click when you turn the key. Dealers have no idea, Diablo has no idea and the performance shops have no idea.

Where did you get your replacement PCM? I had a failed PCM on a 97 ram (no bus comm and wasn't even providing a good 5V rail) and the replacement unit I got seems to be faulty as well (misfiring horribly and setting injector 7,8 performance codes). There are so many aftermarket vendor "rebuilders" out there, all of them claim to fully test the units before they send them out, but after this experience I don't really trust them.

New Level Auto I definitely knew it had nothing to do with that expensive pos

I got same exact diag on an 02 Dakota. I put new pcm in and still no comm. can’t write vin without comm. but the truck runs now and doesn’t say no bus.

The fact it starts and runs tells me there is a break in the network wires to the scanner. If it truly was a no communication with pcm then obviously it wouldn’t run.

I’m not following what your asking. Changing a transponder key to none transponder does NOT cause a no communication with pcm, this will create a no start since immobilizer module is not seeing a transponder chip. Now if you replaced a non chip key ignition switch with a chip one that will not create a no start since there is no module looking for immobilizer information

@@codysautodiagnosticsprogra8706 Now could it be a sensor like BCM or ECU, Fuse maybe, I hooked up a different pcm to look and the no bus light went off but still no start. I'll recheck all fuses and lines I guess. Something I can't see is stopping it turning over, don't have funds to tke it to a shop or tow it.

Can i buy a used PCM? If yes would i need to get it reprogrammed?

Some places sell them plug and play if you give info like vin and model

No BUS only appears on my 1998 Chrysler cirrus after driving it after a certain amount of time And a I guess “symptom” that my car does is that the gages turn completely off and then that “no bus” appears it’s irritating The code that my friends scanner read was p1698 Idk who to see or what to do to fix the car seems like the mechanic my grandfather took it to was a quack because LITERALLY NOTHING CHANGED . They only bandage the stuff that came FROM this issue The brakes AND Despite knowing the diagnosis they unplugged repluged but to not avail and I replaced the TCM WTFFFF DO I EVEN DO

Follow the test in the video. Check powers and grounds at pcm, check lin bus signal and see what modules you can communicate with using a scan tool

👍

if the crank sensor isn't sending signal can cause the issue too

@codysautodiagnosticsprogra8706

No crank signal would not cause a no communication event with the pcm. A bad crank sensor would cause no rpm signal while monitoring pcm data pids. A shorted 5v reference at the crank sensor can cause the pcm to lose communication but the 5v ref was checked in this video.

How was you so sure that pcm is faulty if it had 5V reference

ivan drago because I wasn’t able to communicate with the pcm. I verified communication lines, powers, and grounds, plus 5v ref. If you have all of these and can’t communicate, then module is bad.

Then you need to disconnect all 5v sensors and make sure a sensor is not shorted to ground, this will cause the computer to become a no communication.

Will you always get no bus if it was a pcm issue

No not always. You could have another module taking out the network or could have broken wires somewhere as well
