20 Most Recent 2007 Jeep Grand Cherokee Overland Questions & Answers

I have found the solution to this problem. I have replaced a total of 3 starter motors and has gone away for various periods of time. Further diagnosed when concern happened again starter
would work again after starter ignition feed wire wiggled. I found corrosion build up in connector at ignition feed wire. I replaced connector on wire to starter solenoid and concern has not returned.

What is the current status? I purchased a 2007 Jeep Grand Cherokee from CarMax in December, 2009. The first time it wouldn't start was the beginning of March. The dealership could not duplicate the issue. Happened again a month later, they said it was the wireless remote module and that was replaced. Couple months later, happened again. They said it was the key module. That was replaced. Friday night, happened again. I'm waiting for a tow truck Monday morning. Does anyone know the real underlying issue and the resolution?

What u mean that it cannot be dublicated in the shop?

I have been replacing a lot of TIPM's lately. Basically the fuse panel under the hood. I have done checks for them recently and found it traces back to the main chip. Have the codes read.

OP: Posted by Barbara Frye on May 11, 2016 Barbara. get car serviced? at an ASE shop or dealer? you cant fix this lacking tools, ill not try to guess. did you first erase those errors (push reset on tool)? and see if they return, ???? this is first. have you had work on the pump/tank area. in a collision? here is why. first check fuses. any blown.? then do the cluster self test, no tools needed. posted here 100s of time, need that?, or the free link to the test in the FSM book? posted that too 100s of times here. (ask or search) next is scan it, see all errors, not just the 2 you see now. a real scan tool shows all errors and for sure those that might be related, and any CAN-BUS errors. a real scan tool can see all JEEP extended DTC errors. also post if the instrument cluster is acting odd. in any way. does the fuel gauge work? can you tell? needle steady and correct for reality, QOD: questions of the day, does engine run? does car drive, correctly day and night with bright head lights? does any other feature of the car fail. any at all. no charge lamp failures in cluster, nor volt meter below 14v in the cluster meter of same name (volts)??? 1411 Theory of Operation The Front Control Module isn't receiving a fuel volume signal over CAN B from the Cluster Module. The FCM has to send the PCM a fuel volume signal over CAN C. The signal the FCM sends over CAN C is implausible. my guess is 1403 is the real error. (primary) the fuel sender might be glitching, here is that sensor, in the tank , part of pump, part of fuel rack. in tank.

2007? WK, (i own a 2010 with all docs)same car.REDUXit dont work at all like a 1993, back in the day of running power through switches to run things.,or with banks of relays, to fail.every year,less relays like we did long ago in industry, (pure electronics)i deleted all my fsm quotes.it's to wordy.. (but accurate to a fault)it's now networked + brains (puters),the network map is below.if you look at said map, the CAN-BUS network.is a 2 wire, network for all communicationssaving a ton of wire. (times all WK made world wide)What happens is , you turn the switchand it has this binary/resistance mux logic in the switch that goes to the SCM brain.the SCM knows what you did, and converts your actions into a data stream, "a command".to the can-bus.it arrives, (if lucky)to the FCM and the cluster brain CCN. (IP)the cluster sees that and flashes the click sonic device, and flashes the blinker icon, lamps.If you can't heare that ,this means the command was never arrived.at CCN.the FCM hears this command and it in turn drivesthe blinker bulbs on the 4 external lamps.does hazards work, that be first fact to know..and that FCM fuses, must not be bad.we scan it next. to see if there are errorson the can-bus.or FCM sees garbled dataor CCN errors.or more.... lots more, or FCM not responding, the FCM is over $800 so doing the diagnosis correctly can save a lot of cash.guessing here can exceed $2000.here are the can-buss signals, (using my scope)wanna Gue$$ or Test.?

why double post, ?????ah, but now adds the stud word, ok... same answersee other post by you.not with hubs on car, you cant.take hubs off (non trivial) but did post full fsm pages.then to a machine shop or any suspension shop in townand they press on new ones, with a 5 to 20-ton press.or. just go there and ask them , they will.in fact, the whole job.

a real jeep oem factory part?

mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.

there are 3000 parts. (7000 page FSM too) we cant guess what you are doing,? https://www.techauthority.com/en-US/Pages/Home.aspx post a job, post symptoms. we cant guess that. put us on the same page, (context) please !
