Lost communication with module chrysler
This is how you diagnose a bad module in pretty much any Chrysler Jeep Dodge Ram vehicle. If you find loss communication codes for any module this would be a great way to start. This is for a Loss Communication with HVAC. But the procedure is basically the same for any interior module. You are looking for the following: fused power, ground, and communication voltages on CAN + / -. Your CAN Bus voltages need to be 2.5-6 volts on CAN + and 2.3-4 volts on CAN -. Good luck!

Excellent straight to the point video. One video that teaches you how to fix module related faults. Good job Tech.
I want to say thank you for the step by step info on Chrysler. We finally got the Chrysler 300 to turn on .
Oh how i need a tech like you for my 2006 Chrysler 300
Hello, excellent video, my question is if when placing the new HVAC module you have to program it? Thank you
great video
Exlent diagnóstic thanks
Thx. Greetings from germany
Nice job. I have a u0168 loss comm with security module. But it's starting. Customer claims it didn't have a no start till the installed a aftermarket remote start. 2011 dodge ram 1500 5.7 hemi. Any thoughts after I check what you did on that hvac module. Powers and grounds and can network on the security module?
Does the replacement HVAC Module have to be proxy aligned or programed for it to work?
Excellent, you know how to do in 2012 and newer subarus? I have a crosstreck with this issue Thank you
What about for this code U0141 on a 2008 Dodge Grand Caravan SXT 4.0L V6 Lost communication with ipm front control, fcm, and tipm, I already replaced my blower motor, and blower motor resistor, and my AC or heater work when it feel like it
Can you do a vid on LIN Local Networks? Like a door lock switch to its door module? Only has one wire, no hi or low like CAN C. Thanks!
Thank you

My brothers 2016 jeep Cherokee latitude is doing the same thing. Where is the HVAC control module? Is it behind the head unit that has the 3 control buttons? I see a black box with 2 different harness connectors. His ac system is to be dead and all the fuses are good. None of them are blown.
I have a 2006 Dodge Dakota 4.7L V8 automatic transmission with trouble codes U0101 and P1603. The transmission is stuck in 1st gear and I have a bunch of transmission codes. Any suggestions?

I have 2004 ram 1500 and the instrument cluster will intermittently fail causing my headlights to come on, no wipers, a/c, no turn signals, etc. How can you diag when there is no signal and/or communication because of no bus where the odometer is? Please help !!
Would that be a error code U1403? I have a 2016 Jeep Patriot and all the lights on the dash board all flash on and off like a Christmas tree periodically and where the mileage is shown it says NO BUS when the lights come on...the error code is U1403 that comes back...I just recently had the TIPM changed due to a accident at the dealership, but it is still having all the warning lights on the Dashboard Light Up and when I took it back to the dealership they act as if they've done what they could and they tell me that I need to take the vehicle to a a vehicle electrician to get it diagnosed but my vehicle still under warranty and I feel that it should be able to be diagnosed there at the dealership since they didn't fix the problem in the first place. What do you think? Any advice that you can offer me would be greatly appreciated because I feel like I'm at my wit's end with this vehicle already!

My husband is a driver of Jeep Wrangler JK Rubicon (2015) Airbag light keeps turning on once he turns on the Jeep and never goes away. Malfunction code is U0151. Is this because of ORC module problem? He changed his clockspring but didn't work. He unplugged the airbag connector under the driver's seat and the passenger's seat and plugged them again and didn't work as well. If this is the problem of ORC module, is it possible to solve the problem by resetting the module? or anybody knows how to fix the problem? Thanks!

I need a expert opinion. 2017 Jeep Cherokee. Trail hawk 2.4. Got tints. He removed batt. After a day I got cel. PSCM no communication (still had power steering. Or electric idk which I got. ) month later or so. Cel came one. Tried scanning. My scanned freaked car out. All dash lights and chimes and stuff came on along with front wipers. Reset it with a better tool. Had permanent codes for loss connection to tmc bcm pscm scm can c. Vehicle speed measure and vehicle distance measure. And can bus c code. All relate to the can bus. Could it be the battery is bad? Or should I just reset the ecu by taking off the bat for a while?

I hope you got your issue figured out. I've got the same thing going on with a 2012 300c. Same symptoms. However, I'm pretty sure my problem is related to rodent damage, as the car was barely used and was parked where it had happened to other cars. A low battery or a bad ground can cause the issue, or a broken (or chewed) wire can also cause this.
I have 07 dodge magnum srt8 and I’m getting OBD II codes. They are as follows no communication with HVAP module, lost engine coolant message, lost communication with ECM/PCM, check TPM, small evap leak, misfire cylinder 2, my key stopped unlocking my doors, and my head lights flickering. I had my TCM replaced about 7 months ago at a dodge dealership I’m beginning to think they replaced the wrong part. I would really like your advice if u would. Does this sound like a bad ECM/PCM? I don’t know what to do; also, the car has 83k miles if that helps. Thanks

Did you ever get this fixed
Why did you test all the voltages in a STATIC state? You could have 14 v at the connector when unplugged b/c there's NO current flow. However, plug it in and BACKPROBE it. You could have a voltage drop "upstream" from the connector and when the circuit is CLOSED, you are only getting 7 v at that wire! If you don't need to voltage drop test this circuit, please explain why not. Thanks so much!

I have a 2012 Durango R/T. It has an intermittent problem where it starts and runs for a couple seconds and then dies. Attempts to start without first turning off the ignition result in a 10 second or so crank with no start. The engine will start and run fine after the ignition is turned off. I have had the fuel pump relay recall done and I have checked the relay's function during one of these events, I know the fuel pump is getting power. Yesterday it did it again and I was able to use my diagnostic tool and saw that at least half of the 20 or 21 modules lost communication with the ECU; the ECU showed no faults. It will probably run for months without this happening again. Ever see or heard anything like this?

John Seaman almost anything but usually it’s just a bad intermittent connection. Those are hard to diagnose and you have to find out what lost communication with the BCM. Usually if you don’t notice anything abnormal going on in the truck I wouldn’t worry about it. About the only time I ever replace a BCM in trucks is for door lock issues.

Got busted at job making videos? Just gave up? The luxury of being a dealer tech is having known good parts to plug in like very expensive control modules. Most of the time you’ll probably be OK but you should load test any of those circuits. Good video. If you have the module you don’t have to load test them just plug it in and see if it works.
