I just got another 2007 LR3 to replace the one that I lost. This one is an SE with fewer options, but that is OK.

Once I got the car activated and transferred with the fine folks at Gap Diagnostic, I got these codes from my iiDTool:

I get the TMPS light at random times. I am thinking that there may be a loose connection in the instrument panel or TMPS module since it shows up in both reports.

I will pull the rear A/C controls this weekend and put dielectric grease on the TPMS module as a start, next weekend I will be to pulling the instrument panel.

I understand these things have missed communications and missed messages all the time, but one of them is turning on the TPMS light.

If I start to trace the wires looking for kinks or lost insulation I wonder, does the wiring run down the left B pillar to the wire channel in the threshold and then forward and up to the instrument panel?

What say the Gurus? Am I heading in the right or wrong direction?

Did you clear the codes yet? Briefly glancing at them, I get the feeling that all could have been caused by a failing battery and/or alternator.

 

Yes these are from two different days. The first one with all of the items was on Sep 18 at 3 pm, the second one was on the 18 but at 6 pm in the evening after I cleared the codes and went for a short drive to the store.

The second reading only showed the U0127-87 code which was on the first reading and is lost communication between the instrument panel and the TMPS module.

I drove it yesterday, the TMPS light flashed for a few seconds, showed the little i in the screen then all went off as if no problem. then 10 minutes or so, then it came on briefly again.

This my 4th Rover and my 3rd L319, and I have found the LR3/4 to be so much more reliable than the 2002 Disco 2 I had, but sometimes it takes awhile to sort these little things out.

Jeff

 

Sorry you lost a LR during Harvey. I drove my 99 D2 thru at least 4ft of water with zero issues. I'd have never had big enough ***** to have done that with my LR3.

If you were getting a low voltage fault on the TCM module it could cause the other systems in the Can Bus to loose communication. I'd verify your alternator is putting out 14+ while running and that your battery is in top notch shape. Also make sure the battery terminals are clean and tight.

Also check the TCM for an corrosion.

 

No the iiDtool shows 14.1 volts while at idle. I did keep the second battery from my dead LR3 and had planned to install it soon. Maybe I will put it on the charger and install it this weekend before I tear into the dash and look at the instrument panel connections. ( I want to add the battery anyway, so might as well to it first)

Thanks for the suggestion. If it does not fix the problem, I will start pulling interior panels and looking at wire bundles next.

Jeff

 

While you have the battery out check the TCM, if any of the connections are corroded clean them ASAP. I used contact cleaner and a kids soft toothbrush on mine (were barely corroded, but I wanted 100% clean).

When I got my 06 LR3 HSE last year 2 weeks after owning it, the thing went completely mental! Brakes locked up because it was trying to activate HDC, all sorts of warnings, which started with no cruise control.. All sorts of no communication faults, and it would go to the bumpstops.... All of that over a dying alternator, bad brake switch, and a weak battery.

After replacing the brake switch, cleaning the TCM connectors, replacing the alternator, new battery, and replacing the brakes (was needed when I bought it), it's been very reliable. I also deleted the delicate "T" on the upper small coolant hose to prevent a blow out of coolant.

The LR3/RR were the first LR's with Can Bus and it was picky to say the least.

 

I added my second battery and Traxide kit today. Voltage while running was 13.9 today with both batteries as compared to 14.1 last week with one. I did notice that the previous owner did not have a vent tube on the main battery. I will correct this tomorrow, along with adding one for the AUX battery that I just installed. I will run this way for a few days. If communication errors continue, I may buy a new main battery. If after a new battery, they still show up THEN.... I will tear into it a little bit further.

I want to try all the cheap easy stuff first.

I will keep yo posted as I progress.

Rufflyer
did you ever figure this out. I'm having the p0513-00 (28) incorrect immobilizer key fault from my gap tool. Also battery vent tubes?
Thanks

 

scoutrover13; Sorry for not updating.

After installing the Traxide aux battery kit, I replaced both batteries for good measure and cleared the codes listed above. Idid not have any further problems except I still had the TPMS fault. I replaced the TPMS module in the headliner just left of the rear A/C controls and all has be good since. (well as far as these issues go. I later replaced the front diff, but that is a different thread all together)

Is the code preventing the car from starting? or just showing up in a list? Mine was gone after the battery update.

Only time this code caused me problems was the guy at the carwash, bar and grill dropped my key and broke the case (it also broke a small chip from the circuit board). They tried but could not start it when they tried to move it. I had my wife bring second key. That key would not start car either, and I was getting worried. I used Gap tool to clear the immobilizer codes, shut things down, disconnect both batteries, did a hard reset and the good key started the car once all was put back together. Carwash company paid for a replacement key so all ended well.

As for the battery vents; at each end of the battery along the top, there is a small hole that allows for gases to vent when charging. This is often the cause of corrosion to the transmission module behind the batter as the gas is corrosive and builds up in the box over time. A small adapter piece and a 3 foot piece of tubing ran down the bottom of the engine bay allows the gas to escape and cause little to no problems.

Hope this helps

Let me know if you can clear the code. and if not, how it is affecting the drivability

Jeff

 

Alternator output will vary depending on the state of charge of the batteries and the load on them, lowest i have seen is 13.5V and i have a traxide system as well.
