RX8 instrument Cluster

[cjawahir]

hi all , can you tell me if this chip LR56 chip is the same as 93c56 ?

here is a pic

[Meat-Head]

not as such, but if you can power the cluster can you measure the voltages and n/c at the same time. compared to datasheet for 93c56

Nice image btw.

[cjawahir]

hi thank for the quick reply , its a mazda rx8 cluster , the car was covered with water so all module was damage , so i was thinking if i change all the eprom from all the module, the same key will start the vehicle .

oh and the pic is simple to take with any camera just put a magnifying glass between the camera and IC focus and you get a great super macro picture , so every one here can take better picture , you can also do it with a phone camera .

This is the one. On LR56 is stored KM, but i don't know about keys. Is stored in same eeprom?

Badged differently but Just treat it like a 93c56 mate... And like my friend .not sure the Immo data is in it ... I will find out and post ...

[cjawahir]

thanks guys , I taught it was the eprom but i wonder if it store the immo data also ,

[cjawahir]

here is some pic of the cluster water damage ,
the first pic is where the ic LR56 came from .

the other pic is just to show the damage and also the different ic

have seen worse damage, as it is going in the bin you have nothing to loose. seriously put it in a bead blaster (glass beads not metal) and just waft it around, then try it, just for reference

VW polo 'same shit differant day' fill with water on the vac pump for locking, nothing will make it work, untill you sandblast theat corner!

Ford gaxily (early) control unit SWIMMING in 3" of water board looks like
it's come out of river, blow off with airline, waft sandblaster, take money of customer and run.

If you have acces to distilled water and a toothbrush and a vacum chamber have a go, it's ~~~~ed now, try it, you might like it, dude.

[cjawahir]

hi thanks for the reply , do you think that this might work , will give it a go , the owner is also willing to buy a new one .

i have seen some ford focus with the cluster having the immo code , so i was wondering if this is the same ?

cj

[Meat-Head]

oh, didn't know about the focus though!

Well if the customer went to the dealer they would just replace it and charge lots of ??? ( or $$$), you have nothing to loose the worse that can happen is you miss this weeks dustcart. ( ALWAYS save ANY parts of ANY job untill it is complete)

try it, but just waft the sand blaster like you are spray painting tissue paper.

This LR56 have" writte protection"100%.Read chip is OK but writte not.Use new one 93C56 or C66 (16 bit org)and thats all.You try.

Have programmed loads of them mate ... Read And Write ......LR/RA/RL 56's .... What you on about....?

[MOBILTRONIC]

I mean, several times I had the opportunity to work with these eeprom and each time could not write, but only the new c56 and c66 EEPROM with 16 bit org.If lost content due to moisture and corrosion is another thing.I agree with Lupu-Sandu to also know eating immo info in eeprom because I did not have time rummage about, but only transfer the experience of LR56.Cheers!

sorry mate you lost me a bit .... You have had bad experiences with lr56 eeproms.....?... Did you remove them for reading and writing ...?

[zilog357]

No protection. You can either write or read. I've been able to write on LR56 on Honda ecus.

I don't know of an EEPROM with such protection. Anyway, protected devices are only read protected, not write protected. Also, the reading and writing in a programmer will use the same protocol as in the ecu, so if it would be write protected, it wouldn't work for the ecu either.

[fokker2003]

LR 56 and 93C56 are the same. I read and write all without remove, only up voltage for read above 4V. If you can read it with 3.6V you can write later without problems.

there is no immo in the instrument cluster for the mazda 8, immo for the mazda 8 have a seperate immo box behind the glove compartment, changing of instrument cluster does not affect the immo,

[cjawahir]

there is no im*o in the instrument cluster for the mazda 8, im*o for the mazda 8 have a seperate im*o box behind the glove compartment, changing of instrument cluster does not affect the im*o,

thanks for this , this rx8 carry the prox key , can you if its the box that control the central locking ?

do you have a picture of it ?

[weltune]

here is the photo 9313

[weltune]

this is how it look like

[cjawahir]

thanks so much , my unit is almost the same, the number is FEZ9-67-5DZB

I will post some pic later ,

[cjawahir]

This rx8 is different ,

[cjawahir]

look at this other two module >>.

cj

[weltune]

some RX 8 from japan (JDM) standard does not have immo that is why it looks different, check your instrument cluster whether there is a red key that goes off when you insert the correct key, it will blink when wrong key is inserted n the starter will not crank when the red key blink

this one have immo i have the key its a 4d key , yes its JDM .

i change all the module except the instrument cluster , the cluster is not working , try to program with ad100 pro incode and out code everything say ok program two keys and still nothing , all modules are new .

cj

[weltune]

is the red key at the instrument blinking, if not the immo should be ok, check the starter cranking speed & the spark plugs, starter must be fast enough & the spark plugs is always wet when the car did not start for weeks, crank the engine with the fuel pump relay out to clear fuel in the cylinder & the spark plugs, remember the starter must crank fast enough

[teuton]

Just a sidenote: If you start with full throttle the fuel supply is cut off as the ECU detecs an unregular situation for starting conditions. This way you don't have to take fuel pump relay.

[cjawahir]

the instrument is not working so i cant see immo light , if i scan immo i dont see a fault , even if i use a key without a transponder .

cj

[weltune]

if you can crank the engine the immo should be ok, mazda immo when activated, the starter normally cannot crank, so check the plugs

[cjawahir]

vehicle not cranking from the switch , and if i run a wire to starter it still no spark and pulse to injector .

HRRM, nice feature that is, for granda and sierra have it, vauxhall call it "anti-flood", doesn't always work, sometimes cars start and rev to full throttle, have tried it, good fun doing it.

RX8 roteray engine with the little tips, make sure you leave it running untill hot when you get it running if it's got wet plugs, word on street is you can destroy the tips with carbon build up, apparantly.

[weltune]

than the immo is activated, you need to repair the immo first do you have ids? check the immo status, any fault in it?

[cjawahir]

than the im*o is activated, you need to repair the im*o first do you have ids? check the im*o status, any fault in it?


dont have ids , oh i must get one , but i have the ad100 pro from advance diagnostic .

i will get a new cluster and try to program again .

cj

[weltune]

never use the ad pro before, cannot advise you with it, i think there is a video manaul on the AD site, but you can try changing the eeprom from the old immo box & ecu . put eeprom back to the new immo box & ecu, that should work it should be a 24C02 on immo box & a 93c56 on the ecu

[cjawahir]

ok thanks for the reply , i was thinking about swaping the chip from one to the other , but cant understand why this ad100pro not doing it job , will let you know .

cj

[cjawahir]

I am going to reprogram with the ad100 pro , with out the cluster this time, and see what happens , I think maybe the cluster is making problem with the CANBUS signal .

hope for the best

Did you ever find a solution to this? I am actually trying to reprogram the same chip from the same vehicle and I am having a problem WRITING back to the chip. I was able to read no problem but WRITING gives me a verification error and doesn't write to the chip. I'm wondering if I need to remove the chip from the board?

remove the chip from the pcb.

[DSMKilla]

Just for future reference I was actually able to READ/WRITE with the chip ON and OFF the board. Thanks!

[cjawahir]

This one is now working .

cluster need to be working to program key , use the ids .
