When I hook up my scan tool I get a spike in all of my readings. I had contacted the manufacturer of this OBD 2 scan tool and they told me to take it back and get another one. So I did. I still get this spike in all my readings. Can a remote start system cause interference in the vehicles electrical system? I have had all my grounds checked and are good.
A power or ground may be bad to , from or inside of a control module .
Testimonial: "What is that module under the dash on drivers side? Is that for the transmission? I ask this because when I do spin my tires in snow I get a chatter type of sound down there. Something like if you were to scrape your finger back and forth on a speaker. I also get this sound once I start moving and reach a certain speed. Low speed. It does it only once there, but spinning tires it does it repeatedly until tires stop spinning."
Does it have traction control ?
I believe it does. There is a button for it.
Does it show to be on or off ?
I'm not sure. I don't think there is anything showing on the instrument cluster.
I'm assuming if it showed on the cluster it would be disabled. No light on so must be on.
The traction control when activating can make a clicking sound as it modulates the antilock braking system . It should reduce throttle though
What is your engine running charging voltage ?
It does not hold steady but 12 to 14 volts. I have seen it go lower and have heard this is normal for it to go up and down. Not sure though.
A bad diode in the alternator can cause interference in electrical systems . Can you test a sensor ground at the mass air sensor or manifold pressure sensor ? If the scan tool fluctuates a bad ground can be the problem .
Hi Rob. I haven't had a chance to test anything yet, but last night I was looking at the gauges and noticed my voltage reading was at 16 volts. Today it was reading just over 14 volts. It is pouring rain here today so I have to wait.
We had flooding here yesterday and a power transformer blew out from a fallen tree . Crazy weather :-)
Hi again. Well I tested my alternator and it was leaking way too much ac volts. I changed my alternator and but.....I still get spikes in all my readings that drop to -93.8. That's when looking at my fuel trims. Other readings all have a glitch as well. I'm guessing but thinking the alternator that was in there(which was the wrong one to begin with) must have hurt the computer. The vehicle does run and idle good only I have this problem with those spikes as well as my transmission acting up. Transmission shop says all is good there and have changed pretty much everything already. I haven't tested the sensor wiring you mentioned still just because if something were wrong there I would have problems which would be different I think.
Possible that the diagnostic link connector has a feed or ground issue itself allowing false data flow .
Something else that happen the other day. I got stuck in the driveway at a friends,it was slushy so I give a little gas while rolling forward then stuck. Then I give it more gas still stuck in that position. no response from engine. I give it more gas. No response. So I put in reverse. I move a little bit then get stuck. In that same position I gave it more gas and no response from anything again. This happen before as well.

It could be excessive play in the distributor shaft. Or even a collapsing rubber fuel line.

didnt you get a warrenty thrown in on a £37000 car,did this occur within 90 days of your purchase,if so go to trading standards you have a 90 day warrenty by law,sounds like they took there time finding the problem so they could not be liable for the repair bill,also visit the landyzone website i use it and its a great source of help and advise,get the landrover customer care no of another rr dealer and chat to lr people themselves and go to the vosa website and check on the recalls for range rovers.
good luck

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

Where is the Intake Air Temperature Sensor or the (IAT)Sensor on a 2004 JEEP GRAND CHEROKEE LAREDO 4.0 .???
I Have A Boss Performance chip that i would like to install....Thank's..

What problems are you having ?
Well..If I were to spin my tires in the snow the engine continues revving a couple seconds as though something were stuck. If I do a rolling stop then proceed it will do so sluggish. If I do a pass on the highway it will kick in then back out. result sluggish. I get no DTC's showing. Have replaced both map and maf sensors as well as throttle body. I did get codes relating to transmission but took it to transmission shop and they couldn't find anything.
