Im new to all of this but im desperate for help ! I have just bought a X type 2001 2.5 se 85,000 miles. All looked good apart from the instrument cluster needles were not working. Since then the head lights and turn indicators have stopped working. I have found a place that can look at the cluster although I have a feeling there is something else going wrong. Have checked all fuses and cant find anything. I have had a mechanic on it and after 2 day hes still stumped. Lights on cluster all work and its been plugged in to a diagnostic and showing no faults. Any ideas would be welcome

 

Rotate, based on what you are describing, you are most likely looking at a CAN Bus issue in the GEM module which is what is causing your turn signals and headlights not to work. Then because of how the CAN BUS is wired in, it is also affecting your instrument cluster.

 

thank you for this, Im a little lost at what that actually means sorry, how can it be fixed ? is it expensive ?

 

CAN Bus, the network of wires that moves information between all the computers (ECU, TCM, GEM Module, etc) inside the car. If the car starts sending out a message to check the connection from one computer to another and it fails, it will trigger a code and light the dash up.

As for fixing it, the cost is hard to say as you need to know what is wrong. If it is a computer module, it can possibly get expensive. If it is a wiring issue, it will be cheaper. The big thing is how fast that the source of the problem can be located. If it is well hidden, you can rack up a bunch of hours of a tech tearing apart the car. If it is out in the open, then an hour of labor and you are done.

 

Thermo - thanks so much for you advice... ive had a machanic look at wiring ... earths .. relays and just about everything he could try but stumped but he admited he cant get to that side... I have another guy tomorrow evening that can run full diagnosis I will keep posting thanks again

 

Well both dash and GEM have been sent away, but the company claims that they have been immobilized so they cant test it... Im totally stuck now ... the car was starting so i cant see how this can be the case, Where should i go from here ?

 

Rotate, I would see what the tech with the GEM and instrument cluster says. hard to do anything at this point.

 

thermo- well the company were a little slack if im honest... they just claimed that they couldn't test it... i did have a auto electrician out before i sent it away and he plugged another GEM unit in so Im wondering if its that that's immobilized the dash? they should be back tomorrow (the parts) so i will reconnect and I hope that will re-mobilize ! Then i guess another company to try and test it. I dont suppose you know or have heard of any reliable jag specialists in Horsham area (west Sussex Uk) ? thanks again

 

I have replaced an instrument panel not long time ago due to similar symptoms. Check my thread and if nothing of the mentioned diagnostics in my post solve the problem then you should get a replacement panel and configure it to work with your car with a Jag pro.

Good luck and speedy recovery to your car!

 

Rotate, the GEM has nothing to do with immobilizing the car. If the instrument cluster is out of the car, that is what is killing the ignition. In short, when you put the key in the ignition and you try to start it, the key sends out a signal that gets routed through the instrument cluster and then on to the ECU/ECM.

 

-Arm xt thanks for the link can I ask how much it was to get the reprogramming done I ve heard some horror stories !

 

-Thermo thanks again, the situation is that both GEM and DASH were sent away they claimed that they were immobilized so they couldn't test or repair, they haven't charged anything but they have had the parts for over a week and i need to get back on the road ASAP I dont know why they would claim that when the car is starting fine with both in place just no indicators and no needle movement. I was thinking if the electrician had plugged the wrong GEM unit into the car before he removed the dash that might mobilize the dash ? many thanks aagin

 

Hi i have just put the gem and dash back in and charged the battery when replacing it i noticed there was a cable coming off the positive lead with a small plug on it but i can see where it should be attached ? The car starts sill no indicators or dash needle movement but its not immobilized as the test center claimed.

 

Rotate, try this, press and hold the TRIP button as you start the car. Keep holding it till you see the message center say "TEST" or "ENGINEERING TEST". At this point, tap the TRIP button one more time. You should see all the gages sweep full range. If the gages do not sweep at this point, then your problem is internal to the instrument cluster. If the do sweep full range, then we have other things to look at.

 

Hi Rotate,

I'm from Armenia and paid 25$ for the programming job, which took around 15 min, including assembly. I suppose that in UK the prices will be a bit higher, at least twice, but that's nothing compared to a running car.

Don't worry, it's an easy job, just take the car to a Jag pro who has a functioning WDS / IDS system and you are good to go.


Update us if anything.

Wish you good luck again!

David.

 

-thermo thanks again I have tried the test and no needle movement at all makes a noise but nothing. My hunch has always been this cluster but would this stop indicators working as well ? I will try and send it away again to a company that know what they are doing... or buy another one and get it programmed

 

Rotate, a bad instrument cluster should not affect the lights flashing, but may affect the flash indication. The turn signal stalk sends a signal to the GEM to actuate the lights. The GEM then toggles the turn signals on and off. In parallel with the lights, the GEM sends a message to the instrument cluster via the CAN Bus that the left or right turn signal is blinking and it sends a signal when the light is on and removes the signal when the light is off.

 

hi thanks again thermo, hazards and the key fob activate the indicator lights but nothing from the stalk, I think i will have to try and get it to a jag garage and get them to have a look.

 

Rotate, if the hazzards and the keyfob are activating the indicator lights, then I would be first looking at the turn signal stalk and replacing that. It may be that the stalk took a good hit at some point and now it is acting up. The keyfob and hazzard switch still go through the GEM module for the lights. So, atleast the output section of the GEM is good. Now it is a question of whether the problem lies in the input portion of the GEM or is the turn signal stalk.

 

ok so ive played again with the car... it appears that if the ignition is turned on and off a couple of times I get indicators back but the remote lock/unlock doesn't work flash works but full beam does not stay on... on and off again and key fob works but no indicators of flash...that does suggest CAN bus again ? also noticed the wipers come on sometimes when ignition is turned on... At least i can get them working and get it to a garage if i need ! Still no movements on the needles in test mode the speedo vibrates a bit... nothing else.
