JEEP RENEGADE COOLING FAN AND IAT CIRCUIT FAULT DIAGNOSIS
ฝัง
- เผยแพร่เมื่อ 22 ส.ค. 2024
- In today's case study we have a 2015 Jeep Renegade with the 2.4l 4 cylinder Multiair engine. The customers complaint was that the cooling fan was not working. The customer did her own troubleshooting and found that the cooling fan was bad. She requested for us to replace the fan and we did. But even after replacing the cooling fan, it still did not work. The check engine light is illuminated and using a scan tool we were able to read that there are 2 different codes present. P0481 Cooling fan 2 control circuit fault and P0113 Intake air temperature sensor 1 circuit high fault. Follow along as I take you through the troubleshooting steps I took in order to diagnose this vehicle.
Thank you for watching!

I'm sure that you know, but one of the best tips I was ever given by an older tech was that if an oxygen sensor wasn't coming out. Stop, dump a cap full of brake fluid onto the oxygen sensor, and walk away for 5 minutes. When you come back, the sensor will easily come out. His explanation is that the brake fluid melts away the carbon that is holding the oxygen sensor in the manifold and I have used it a bunch of times with success!
Great video btw! For whatever reason, I wasn't being notified when you were posting videos! I'm glad I caught this one!
Voltage Drop Diagnostics I’ll defiantly have to try that trick! Thanks 🙏
Me too! Thanks for the tip!
So brake fluid stops u from braking or breaking the sensor. Cool tip. I will try it.
ill be trying this lol
Excellent tip.I for sure will be using it in the future repairs.thank you!
Keeping a library of how the different sensors work is critical to success in troubleshooting.
There are many important life lessons in this video, thanks for allowing us to follow along. People who think auto repair is easy need to understand how often secondary problems can happen during a repair, including stripped threads on a device that was simply in the way, broken wires unrelated to the issue, and the confusing hands of someone else involved before.
that's why as a mobile tech I stop way before I dig a whole for myself..
You really cover a topic thoroughly. You should have 13 million subs, not 13K.
Thank you!
I think Fiat hired the old retired British Lucas wiring engineer from the 60s and 70s and told him "Make it cheaper". Lol.
You are making great videos showing and explaining the circuits and how they work. Much appreciated. Keep up the great work.
Thank you!
Loving that oldschool AFI playing in the backround!
I like the way you explain how system works how they share the power source
Thank you!
I hope you make more videos like that can you please do video like tour box tanks
Eric,excellent video. I truly enjoy your videos simply because you give an excellent explanation of how the systems work by using the wiring schematic. Every video you post you do a great job of teaching myself the knowledge of reading a schematic. Thanks much and you and family have a happy thanksgiving. 👍👍👍Artie
You Sir, Eric O, and Ivan have the chops of becoming instructors at an automotive collage!!!!
The explanation at the beginning was a little vague when mentioning that the owner coming to the conclusion of a bad fan that she had checked the relay and fuse but didn't mention that she found the fuse was bad. also if the original fan was checked by the first mechanic, or you double checked the original fan to make sure it was the cause of the fuse blowing... But all worked out well. Thank you for another great diagnosis and repair.
She told me "I already checked the relay fuse thingy" lol
Fantastic job! Thanks for the helpful and informative video as you take me through all the troubleshooting steps! Appreciate that!
Perfect way to end the weekend is with a video from you haha!
Ha! Thanks!
That vehicle is a rolling pile of crap but it doesn’t seem like the owner takes good care of it either. Great video!
At some point I was interested in getting a Renegade but people are seeing that the Renegade comes with a lot of issues. The problem you showed just demonstrated that without a good mechanic like you we can be spending a lot of money in that vehicle. So no thanks, no a Jeep for me. Great video. 👍
Thank you for watching!
You actually wouldn't be getting a jeep. The renegades are actually built by Fiat.
great video, I like when you show and explain the diagrams. Those heat covers cause so much damage.... engineers know what they're doing. $$$$$
Thank you for your detail explanations of the circuitry. Learned a lot from you. Keep it coming!
Good fix. Sure a lot warmer than here. Freezing rain and sleet here.
Good Man . Some people shouldn't even be allowed to Clean Toilets
Thank you for all the videos you do. I have learned a lot and for the great explanations that we can all understand. Some of your videos with Oz are real funny hope you make more together.
I have fixed this code before. I was right! it was hard to diagnose but my diagnosis was correct. Blown fuse and burned fan motor. 2010 Dodge Charger I’m a learning mechanic ..
Thank you Thank you Thank you... this vid saved me a lot of money. I really appreciate you
Erick men I like the way you explain everything good job. My friend
Multiair is Fiats version of Valvetronic that BMW uses. They vary the intake valve opening to control engine speed, they do it hydraulically instead of electromechanically like BMW does.
I really enjoy your work and your diagnostics thanks
Thanks for watching!
Great video. Helped me with my fan issue. Thank you.
Thank you so much for the video this will help me a-lot Im going through this problem with a 2016 jeep at my shop the fan is working but the code still there Im going to check that fuse
I think this just fixed my jeep! Thank you!
Very well explained Eric. Thanks for sharing! 👍
Keep theses coming you were great ...
Your a great teacher. Thank You!
Thank you
Me gusta mucho tu canal bro, explicas las cosas de una manera fácil de entender y sencilla. Ojalá llegues a tener muchos mas subscribers. 👍🏽
Good work steps Erik.
Nicely done. One day I'll understand how to read wiring diagrams.

I've got the guys at my shop working through this playlist based on Jorge Menchu's method. Within 1-2 videos they could understand way more than before so it's definitely worth a look.
@@jwilkers1 Thanks, I will check it out.
Good stuff man, like your style, hollering from the Caribbean, Saint Vincent and the Grenadines
Thank you for watching!
There's a recall on those. This is a very common problem
I’ll have to look into that. Thanks for watching!
On the cooling fan
Yeah. I can't remember the years off the top of my head, but I work at a Chrysler dealer and we've done dozens of them. So many we keep several in stock.
Jeremy Scott if there is she can be reimbursed by dealership
@@rahrah8076 ya
I watched youre video and i can says it helps me alot at work... i hope you can teached me how to source out the diagrAm for a multi brandas or cars from old to new... is in the all data apps.
Thank you Eric. Good job. Have a blessed and safe week.. Blessed Thanksgiving to you and your family.
Blessings
my master technician
I like that way you are made this video
Nice job
Thanks for the UL tho I replaced the 50 amp fuse & It blew again maybe the fan motor shorted?? Know what the fan motor resistance should be??
Very good video 👍 thanks for sharing .
Very helpful 🙏🙏🙏👍👍👍
You make it look easy
Hey bro nice vid Where did you get that computer program you was using ?
I like your process thanks for sharing
Thanks for watching!
Great video! Thank you!
great video with great info thanks
So if those wires on the IAT would of tested good.... What do I test next? The engine coolant temp sensor or the oil temp sensor? I'm asking because my fan will not come on. I'm trying to eliminate all possibilities before buying a new fan. I'm almost certain a AC PRESSURE SENSOR COULD KEEP THE FAN FROM NOT COMING ON.... I also have a P0481 code but my fan won't run in high or low speed. I also had a blown 50Amp maxi fuse. I replaced it and still no fan working.. ive had to walk away from it several times frustrated... Can you please tell me the location of the other power distribution unit where the last fan relay is at? Any other help would be great too.....
Gracias brother,thanks bro.for the videos helps a lot.
I have a 2018 renegade, and the cooling fan is not coming on when ac is turned on. Fan will only come on when engine needs to cool the radiator, checked fuses and relays already, any ideas where to check next?
Can you please tell me where the purple end of the coolant wire harness connects to. I have a rental and there's a small purple connector that I have no idea where it connects to but I think it's causing my radiator fan no to come on. My cars been overheating out of no where and there's this one purple harness connector that is right by the radiator fill tank that I can't seem to find where it connects to. I've been like everywhere but I can't find an answer.
Great vid...nice info and fix
The wiring diagram said fuse 7 is a 40 amp fuse but it had a 50 in there, I've been having a problem with my wife's jeep burning up the fans is this something I should look into
Great job again like always
Very great vidio
i have the same ride and trying to fix why it’s overheating i have a relay switch but don’t know where it’s located
Great video thanks for sharing. Chrysfiat wiring quality is very poor
Where have you been all my life, lol!!!
You just made me blush lol
My customers suck at diagnosing their own cars since 80-90% of the time their diagnosis is way off. I normally try to get diagnostic time since they would be wasting their money almost every time. Some customers see the wisdom of this and the ones that don't are probably better off at a shop down the road.
Great job 👍🏻
Good video thanks
Also a blown fuse can cause to run low side
where is the high speed relay located, I found just T07?
The subscribers are climbing .. more comments people
Thank you!
good work . but i was hoping you chick the ground after repair .
Voltage Drop Diagnostics, can you help me, I'm pulling my hairs out over this 2017 Jeep Cherokee 2.4. The engine temps creeps up when sitting stationary like at a stop light etc. but when driving the temp come back down to normal. Does the 2017 Jeep Cherokee have 2 fan speed setting? With the A/C on the fan does work. I let the Jeep idle in the garage, it got up to 228 and the fan never kicked on. The only fuse I found was a mini 5 amp "radiator fan enable" fuse. I don't see any relays or any other fuses. Would appreciate if you can guide me in the right direction.
Having the same issue with my 2016 2.4 cherokee sport. Gets up to 228-230 before fan kicks on.
In town it run 219 to 228 consistently
0:10 that Colorado in the back needs to be in a junk yard haha
Gracias compa good video.
Gracias!
It may sound like a 'dumb' question, but the TPS % closed throttle on your mini-scan tool...shows to be near 17%. ???
Where is the relay located I can’t find mines
Great video man
Those cooling fans are under extended factory replacement. The dealer replaces them for free.
I was unaware. The customer had already purchased the part. She just wanted me to replace it. Thanks for watching!
@@ADVANCEDLEVELAUTO Yep I replaced one with OEM unit for a customer about 9 months ago. Week after we replaced it he got the notice.
Good job!
Thank you
It is FIAT engine Multiair is petrol (gasoline in US) and MultiJet is diesel.
I bet you're grateful for Chrysler products, because they bring a lot of money into your shop lol Nice job on the diagnosis
They also bring headaches lol
Where did you find the diagram for the splice locations looks like a different program than alldata?
Grasias por la clase
Gracias por mirar el video!
Where can I find the circuit diagrams?
Thanks bro ..... Great explanation of faults .... Could you tell me, which is the software for diagrams, you are using?
Alldata
@@ADVANCEDLEVELAUTO ok thanks bro
Not sure if it has been asked or not but where do you go to get those wiring diagrams?
so if you jump iat with paper clip and wiggle connector what would you find
Please, what the number relay fan 1 I can’t found it
Superb
where are you located? I need a good mechanic like this near me!
that wiring is a repair waiting to happen wow
nice video .who sell that percing probe you have
Can i have wiring digram for my jeep compass 2019 please
So what blew the 50 amp fuse
The original fan motor burned out.
ADVANCED LEVEL AUTO but you changed the fan you did not test to see if it worked
When we removed the old fan I bench tested it and it did not work.
nice job Eric What blew the 50 amp fuse?
The original fan
I noticed a basketball goal at your shop ?? You want to get dunked on ??
What is a basketball goal ..lol
You don’t want none bro lol
ADVANCED LEVEL AUTO I will dunk on you like Pippen did to Ewing lmao
@@OzMechanics lol
Sheesh. Makes you want to pierce the wires for testing. Were damned if we do and damned if we dont.
Those renegades should earn the most idiotic design of the year award.
An underhood fuse box facing sideways is just perverse
There is a recall on the fan...
How about re-doing this so the computer screen is NOT out of focus!
Osm vidio bro
I'm going to say when I 1st got my 2019 jeep compass trailhawk I pull up at the gas pumps and realized I had got a fake ass Jeep
What causes this
Topnotch diag and repair
