LAND ROVER RDS/EON DIVERSITY PU-9836A

[turner]

I would really appreciate some help with this Radio Code

I do ecu's and immo's but not done any radios so far.

I have the above radio and understand that the code is in a s2914 smd, can anyone confirm this is correct and tell me where it is located in the radio. here is a link to the service document which may be helpful in showing where it is and may be handy for others too. http://p38arover.com/rover/p38a/Clarion_PU9836A.pdf

I have a few of these to do so would like to find some software that will extract the codes too if possible as this is likely to be a regular thing.

I hope someone will help me.

Thanks

yes,S2914 link 93C46 read on 16-bit

Thanks for that, Any idea where it is? there are a lot of daughter boards in there and a casette deck too.

I dont want to start striping it down to find the chip if I dont need too.

@turner

Here's the layout for PU-9836A.
You'll need to remove the deck, to access eeprom.

Thats perfect, can you tell me where you got the image from? I think I have seen something similar on here before, it could be useful.

Thanks, looks very useful, gave the thread a nudge too....

[turner]

Well I tried to read the 93c46 with a soic clip on board with my xprog m and couldnt get a good connection to pin 1, removed the chip and now getting connection errors to even more pins so it looks like the chip is screwed.

Does anyone have a good dump they could let me have so I can write it to a new chip? Maybe they could let me know the code too..?

Thanks

@turner

Did you read chip as 'rotated'. If you don't know 'rotated', then search on DK... there's plenty info on it.

[turner]

Didnt realise it was a rotated chip, connected correctly now and says "bad contact at pin 6" so looks like its all over for this chip.

Here's an un-tested PU9836A dump... may help.

Thanks Bonus2010

I will try it tomorow, I have some rotated chips on their way.

Can you explain or PM me with where the the securty code is in this dump.

Thanks Again

Reckon the code is 2415... (or sometimes reversed 1524)
Open the dump in hex editor.... not much bytes to choose from...:alberteinstein:

Thanks once again, although I realise that there were not many numbers to choose from the number of combinations and waiting an hour to try them if I didnt get it right quickly didnt bear thinking about LOL...

Really do appreciate your help with this, especially as I feel such a fool for wreaking the chip by connecting to it wrongly in the first place.

Sometimes its the simple things that catch us out.

Hello
ask for help
have a radio same model, already read rotate eeprom, now the display shows only 4 dashes, can not enter the code; is there a procedure to enter working code ?
thanks for help

Hi,
I have problem with same model, read rotated 93C46 in 16 bit mode, dump looks like is good, I now can't confirm code. enter numbers 4355 or 5543, but "up" button do nothing anyway.

Hello

93c46BX
=======
If the wrong code was entered at three times
1. Wait for more than an hour at the necessary wire
connections.
2. Press BAND button for two seconds.
3. Input the correct code.

[BeianM]

is there a way to remove the wait state? This radio we waited an hr for it to offer us to enter the code, it was ---- in display. we entered the code & it just sits there, it has not accepted the code the no.s are still on display, cant enter anything else. Guess we have to wait another hr. The .bin has 62628484 in it, we entered 6262. Will try 2626 next. Was wondering if 8484 was the wait state?

you must read eprom and post dump,for code and reset ....93c46 rotated.

[BeianM]

I did check in NYO but my version does not list Land Rover.
Can the wait state be reset? how to do that then.
Thanks for the info.

I am not sure but I think your dump has been read at 16 bit instead of 8 bit ( think first 2 bytes should be AA AA ) but I don't know what bit it should be read at

[BeianM]

Thanks, I will read it again. I'm using upa, the menu gives x 16 option. I just used the standard preset, it does not say what it is reading at.

[turner]

Just use this file.

Code is 1111 so its fast and easy to do 198238

[BeianM]

Thanks for this, I tried but the file now reads full of FB FB FA FA etc!! so guess its buggered.

[BeianM]

I took the 93c64 from another PU-9836A that has an amp problem the first line of code is 55555 6464 ECEC
I have tried 4646 6464 6446 & 4664 now waiting another hr to try again, Any thoughts chaps?

[smoggy]

I am not certain but I think when you have read it correctly the first 2 bytes will read AA AA

[BeianM]

hmmmm, I'm not sure what i'm doing wrong then?
I read it with upa-usb in 8 bit rotated.
pins:
1 nc upa
2 vcc 9
3 cs 7
4 sk 2
5 di 6
6 do 3
7 gnd 5
8 org 4

[smoggy]

I have no idea how to get dump but all the dumps I've seen for this model start AA AA
maybe one of our experienced decoders can confirm this or advise

[zvasile]

try reading and 16-bit

[BeianM]

So, this 93c64 is a S2914.
UPA has a preset for 93c64 in both 8 & 16 bit which I tried.
UPA also has, I just found, a preset for S2914 16 bit.
I just read with this & I get AAAA 2132 3042
NYO for clarion says either 3221 or 1223
I just waited for the hour to pass & it is not 3221.
waiting before I can try again. Will update.
Thanks guys.

[smoggy]

or maybe 2132

[BeianM]

It was 2312
So it is a 16 bit S2914 in upa usb & not a 93c64 8 bit
Cheers all, we got there.

Hi is there any chance i could have a copy of this file for refference please
