Do you have the pinout to both connectors on the PMS?

Hello !
My 1996 C180 can't start. Mechanic told me the PMS is the problem because they tested every non-electronic possibility for my problem. However, they also said they can't communicate with the unit in order to get error codes, it doesn't return anything apparently. What do you think ?
If you have 38 pin connector, you can build simple diagnostic tool: czcams.com/video/xdVemMjTMTk/video.html
@@jusubbidiy thank you for the suggestion.
Another question, would buying another pms module, same car same engine and swapping it work ? These only cover engine management and aren't specifically coded for one car or am I wrong ?
@@EarscrapperOfficial I'm pretty sure you can swap PMS without any problems.
@@jusubbidiy thank you so much, I will let you know how my situation goes, could be helpful for other people coming across this video
@@jusubbidiy Hi it is me again.
You previously said I could swap my faulty PMS module for another one, same part number. I'm looking into this solution to my problem but I'm a bit concerned about something and can't find enough info online. My 96 c180 has an immobilizer system. Is it tied to the PMS module, meaning swapping won't work as keys won't be recognized, or is the immobilize managed somewhere else ? What do you think ?
Hello, what exactly trimmer plug does? What is this for?
With trimming plug you can change timing advance. Some values also add more fuel. 110 ohm is for 95 octane fuel with cat. 220 ohm is same but add +6% more fuel. You can find values in Mercedes technical documents.
i came across you channel some days ago. my 1993 c180 w202 gave some sign and suddenly stalled on the road, after 6hours it started and died again whil still parked. it was toed back to the house. it will statr and steem smoothly but when you turn off iit will not start again until after 3hours. but today it starts and run again and again but i am scared it might stll if i drive. what do think pls
That model has mechanical fuel injection. It have problems when aged. You can also check distributor cap for cracks.
@@jusubbidiy it has IAC, common rail fuel injector. no MAF and has the ICM PMS. it runs and drive but can engine can die without warning. a crank and the engine wiill run and drive
@@jonathanisi6016 this model has problems with wire insulation. Mine has broken iat ground wire and then engine thinks that there is +30'C all time.
@@jusubbidiy thanks for your quick response, are you suggesting that i get the wirings harness checked
@@jusubbidiy a very big thanks for your advice, it was helpful. i have been able to locate the damaged area of the IAC plug and fixed it car runs perfect. thanks once again.
My car is running fine but it loses power on highways, im not sure if its the throttle body or the ignition coil. I tried taking out the trimming plug and it doesn't make a rough idle when reverse gear so idk what is the issue.
Is motor temp ok? Is catalytic converter ok?
@@jusubbidiy temperature is fine running 80 deg, im not too sure about the cat itself since it hasn't been checked after i bought it 2nd hand.
@@ehgg_6116 If cat is clogged it reduce power a lot. Which engine do you have? My 1,8l is very lazy. My wife's Toyota Yaris 1,3 has more power than this old Mercedes 😂
@@jusubbidiy yeah its the same old 1.8l, I'm even surprised this car can go 140kmh
@@jusubbidiy should i do the paint thinner trick?
Hi, is it normal to check fuel leak into the vacuum line that goes to PMS? Thanks
I don't understand that guestion.
Fuel leaked into pms seemed like a bad thing, shouldn't the vac line be higher than the injectors or there's some type of backpressure?
@@ehgg_6116 I think it's impossible to flood pms. But If you think so, you van drain it. Just remove battery minus and then remove pms from vehicle and tuen it upside down. Map sensor is closed, so Fuel can't go inside pms, only map sensor which is integrated to pms.
@@jusubbidiy yeah since pms is an old tech unlike the later ecus it would be easier to fix, hardest part is taking it apart and glueing it back
@@ehgg_6116 you don't need to open that, just turn it upside down.
Hello friend do you know if the map changes
I don't understand your question. But maybe this video helps: czcams.com/video/fBTLAULiais/video.html
Hi c200 suddenly cut off the ignition
What should we do
Have you scanned error codes with hfmscan? Check wirings first.
I have problem with pms.. if engine idling can not smoothly and rough and limps and than i try to swap with other pms the idling can smootly n not rough n what should i do to repair pms?
If problem is only with idle, you can check idle switch circuit from pms.
@@jusubbidiyhigh friend i had c180 high idle i changed the throttle still no change same problem do you think pms controller can be the problem
@@ahmadlbl did you check wires with multimeter?
@@jusubbidiy no bro do you had a link for harness wiring diagram
@@ahmadlbl www.hfmscan.com/files/wis_pms_pinout.pdf
in the end, your car has poor idling same as mine. is this normal?
I can't remember is that normal or not. I also had problem with Idle switch. But that was poor soldering on pms and I fix it also.
@@jusubbidiy i literally changed everything. including looms. still have poor idle. there is only 2 part havent changed, PMS and throttle body.
@@ALINUED Have you checked that idle switch? czcams.com/video/c5xnpnANt_M/video.html
@@jusubbidiy no, I will check it thank you, should I turn the engine on for measure or just the igntion mode?
@@ALINUED Ignition mode is enought.
