Do you mean with the IIDTool? Yes I did, but only recent. Not done much driving since.

Hi again BSM, you can do it with the IIDTool or just with your battery leads.

Either way, see how you go once you do a bit of driving.

The reset with the battery leads I did before. The IIDTool version I only discovered last week, it is more spectacular Razz.
The U3003 17 error is still there. I'll do some driving and hope the limp modes stay out, then it's fine for me.

Belgium 2008 Discovery 3 TDV6 HSE Auto Alaska WhiteDiscovery 3

Bad news. Last night limp mode AGAIN ....

P0101 00 (68 ). It was less than 1000km since previous P0101. U3003 17 (AC) is always there, still thinking the voltage can cause the P0101.

@Robbie, I tried to check the separate voltages of different ECU's but couldn't find it. Where can I read these?

This is from my D4, but a good enough demo. Enter the live data menu and type vol in the search box and all ECUs that report voltage will be listed for selection:

My car apparently got an alternator that is on its way out
battery 12V when car off
battery 12V when car driving
I don't get any errors when driving
EDIT - I haven't plugged a scanning tool in though yet!

I know that battery's lose power after some years. That's why I replaced mine, there were no other symtoms of the battery being weak, only some random (?) errors. I have a new battery now, but still having errors. Also the measurements were done with the new battery.

Aah, that's why I couldn't find it, it is in the external app. I don't think it is possible with my non BT tool. I can only connect it to my PC with a USB connection and I can have the view like attached.

No search box, no big screen, no graphs, ... I think no more info than what I see in the dash display. Sad

Ahh, the IID Classic. No search tool for you but you can still access the lives values manually.

Perhaps time to upgrade to a BT as GAP like to look after their customers?

That doesn't look good, how and where did you measure this?

Lucky you! Life is so unfair, my car is perfect, no dealer can find a problem, but it keeps going into limp mode once every 1000 or 2000km.

Hi bsm and this is just a suggestion and probably has nothing to do with your issues, but there was a problem with a loom connector in D3s, located down behind the cranking battery, that caused all manor of strange issues, if it was not securely connected.

Again, this probably has nothing to do with your issues, I never had the issue with my D3, but someone, Robbie perhaps, might be able to clarify whether this could be a potential reason for your problems?

Ok, walked through all the live values and took some interesting ones out regarding voltages. Outside temperature 23°C, engine little lower then operating temp, went for a drive 2h ago.

Auxilary heater
    Low voltage threshold 9.9V
    Operating voltage 13.7-13.8V


Engine
    Battery voltage 13.8-14.0V


Instrument pack
    Control module power supply voltage 13.5V


Steering angle
    Steering agle sensor actual voltage 14.2V

btw.: I saw the steering agle is not 0° when steering wheel is pointing straight, is that a problem? It is a few degrees off.

Transmission
    Actuator supply voltage 13.5V
    Power supply 7.0V !!


Ventillation
    Sensor supply voltage 5.0V

Didn't update because I have an android phone and tablet, most support is for IOS I thought. And I was not planning to use it daily, just in case there is a problem. I was hoping problems were not a daily issue, maybe I should change my mind on that ...

Thanks for the suggestion. You don't want to know how many hours I spend on this car, what I've tried ....
I've disconnected all connectors I could find in the engine compartent, including the 3 down behind the cranking battery. All connectors looked nice, clean, dry and not corroded. Thumbs Up

The IID support for Android is comparable to iOS.

If the SAS error is causing no issues I would ignore it for now.

7v does look odd as I don't recall anything on the vehicle operating at or near that voltage.

Check if it is regulated first (key on engine off vs engine running).

Indeed the 7.0V looked strange, that's why I did put it in bold. With engine off, exactly the same 7.0V !?

I would like to ignore the voltage error, I'm just looking for something what could cause my P0101 ...

I have a new idea, I don't know where it came from, it was just in my head when I woke up this morning. Not going to mess up this tread, I already had a P0101 tread, I'll continu there on page 2 .....

I measured the voltage across the battery terminals
I am replacing my alternator soon, because although I don't get any warning messages, the low voltage seems to affect the running of the car (the car runs much better when it finally gets to 14.5V after 20 minutes of running!)
Mine is a 2005 model
