Faults that will not clear

[juddcampbell]

When my car was in the shop for the body work they ran diagnostics and most items passed however there were many items that did not clear.

Including Faults on:
CEM-LS Central Electronic Module (Low Speed CAN)
PAM - Parking Aid Module
BCM - Brake Control Module
RCM - Restraints Control Module
CCM - Center Console Module
SAS - Steering Angle Sensor
CEM-HS Central Electronic Module (High Speed CAN)
CEM-LS Central Electronic Module (Low Speed CAN)
PAM - Parking Aid Module
SUB5 - Sub Woofer Amplifier
HLM - Headlamp Leveling Module
DDM - Drivers Door Module
PDM - Passengers Door Module
8 Cylinder ECM - Engine Control Module - Bank 1 ???? what ????
12 Cylinder EMS-P Engine Control Module Bank 1
12 Cylinder EMS-S Engine Control Module Bank 2

I am not sure if they used the AM software as it lists DB9 from 2004 onwards. I would think the SW would be different from 2009 then again in 2013

I have noticed my battery is low when I hook it up to a trickle charger however it has always started. I had the battery tested and it tests fine.
I have had the car not unlock before with the remote and I had to use the manual key.
The quantity of errors lead me to think I have a bad battery or a parasitic draw somewhere in the car which drops the battery voltage over time.

I am 3+ hours drive from the nearest dealer.

Might need breakdown cover .

Sounds like an electrical fault, like you suggest, could be battery related. Does the trickle charger show the battery as fully charged when left on for a while?

Yes it does show fully charged after sitting on a charger for the evening. I may want to read up on how to put the top up manually!

just an update, the fault list was from when the car had the battery removed.
the final scan was just two errors.
Low Speed CAN
Parking Aid Module

I ordered a new reader so I can track issues with these and reset them.

Hey guys I’m running into the same problem they all started coming after I removed the battery in my car.
Having this for more than. A month now
All of my dials in the car stop working all of a sudden even the ac.
Pls help me out
Thanks

First thing I would recommend to anyone is buy a foxwell reader with AM software.
https://www.foxwelltool.co.uk/wholesale/nt530-mult...

Disconnect the battery for 10 mins
Reconnect and plug the reader in.
Remember there are 2 ports : one for engine and transmission
One for everything else.

Step through each module note what is flagging up and clear the codes.

Go drive the car for 10 mins and then use the reader and compare what codes are still there.

If you are having issues with infotainment or cluster once you reconnect the battery. Check every fuse in the footwell fuse box and in the boot fuse box.
Not just the ones you read in the manual, check them all as you don't know which ones cause secondary failures/symptoms

Actually if you don't have a reader, start with the battery disconnect and fuses. Its free and simple.

Making sure that the battery connections are clean and tight would be the first thing I would check after the age of the battery.

Even with battery tenders, a battery is reliably good for about 3 years. On my wife and kids cars, I change them every 3 because I hate listening to them complain when the car won't start. On mine, I'll go 4 or until the first time I try to start it and it hesitates a bit before spinning over.

I like my Foxwell NT520 - does almost everything I have asked of it (but not the steering angle sensor!).

[Cjmoveen]

I do have a launch scanner but it has only one port so I will only be able to scan one module at a time.

I did check all the fuses also. They are all good. I will disconnect the battery and see.
Thanks

[Cjmoveen]

Just to be safe there is no immobilizer which will sound a alarm or prevent me from staring the engine after I remove and reinstall the battery right ?

[Hutch525]

Your good to just remove the battery

[Cjmoveen]

Still no luck 🙁 still all the same codes. My dashboard is still acting up, illumination not working , rev gauge and speedometer everything’s blinking and Turing on and off none of the controls also work

[leman600]

As people are saying battery issues can cause a myriad of unusual symptoms but the 2 faults below could explain much.
Can bus is common to many items and this looks like it may have damaged wiring which has brought all the low speed CAN down. Any wiring touched whilst doing the battery for example. Seat move to an unusually forward position....
Good luck.

E001 Low Speed CAN - Transmit/Receive Error.

DF07 Low Speed CAN - Low Side Short Circuit To Low Speed CAN - High Side.

I'm not sure your code reader is able to properly detect the systems.
What is the battery voltage with everything switched off - have you got a multimeter/voltmeter? It must be a minimum of 12.6v. If it is say 11.8v then its no good. As soon as you start the engine the current draw will drop the voltage to around 7 or 8v. At this level the central control module will start to shut off the less essential circuits (radio/windows/heater/heated screen etc) to try and maintain voltage for the engine/gearbox etc. If this level is reached all the fault codes will return.
Once started what is the charging voltage? It should be above 13.8v. If only say, 12.9v, as soon as you switch on an additional circuit it will drop to 12.6v or less i.e. the battery is not being charged.
If the battery voltage, all circuits off, is say 12.8v indicating a good battery, then switch the headlights on for 10 seconds while watching the voltage. It will drop to say 12v then switch everything off again. Keep watching the voltage all the time. A good battery will 'recover' at a rate of roughly 0.1v every 2 or 3 or 4 seconds and pull itself back up to 12.6v after 5-10 minutes or so. If the voltage never recovers to 12.6v then its too tired and should be replaced.
Very often dials swinging back and forward are an indicator of a low battery voltage.

Before I went any further, I would replace the battery. Many cars now need a high voltage service charger to access or program the ECU,s, usually around 14 volts. If your voltage is low, or even below 13.5V you may find this is why the ECU's are not resetting.
Alternatively, have a running vehicle connected to your jump-start points whilst you try and reset the codes.

Slightly off topic but not sure that the Foxwell 530 will work on post 2016 AM, I was looking to purchase one myself until I read the info below on the Foxwell Q and A 2016 onwards uses Bosch ECU.

Foxwell NT530 Aston Martin V1.10.009 update:

Adds new cars 2004-2016 Aston Martin 4-system basic diagnostic functions: reading version information, read DTCs, clear DTCs, read data stream etc.
