Coduri secrete BMW E36 ( Teste secrete bord )

Va prezentam modalitatea de a intra in modul test service, prin butoanele de la bord, fara a avea nevoie de mufa OBD sau alte instrumente tehnice, la modelele BMW E36 ( gen BMW 316 i ) , precum si semnificatia detaliata a rezultatelor acestor teste.



Cand tii apasat butonul de reset si cheia in pozitia 2 bordul intra in teste... la primul test iti apar cele 6 afisari dupa care acele se dau peste cap :

1st display: BMW PART NUMBER (6 digits)
2nd display: CODE NUMBER (5 digits) Internal Coding Plug #
3rd display: K NUMBER (4 digits)
4th display: CHASSIS NUMBER (5 digits) this is part of your VIN
5th display: SOFTWARE VERSION (3 digits)
6th display: REVISION INDEX (2 digits) Hardware #

Daca atunci cand iti apare testul 1 apesi pe butonul de reset o sa vezi ca trece la testul 2 si o sa-ti afiseze alta valoare... si tot asa pana la testul 6... de la testul 6 pana la testul 15 o sa iti apara asa "-------"
ca sa vezi se valori indica si la celelalte teste cand bordul intra in teste apasa pe butonul de reset pana ajungi la testul 14, iar la urmatoarea apasare sa tii mai mult si la testul 15 o sa-ti apara "L on" si cand apare "L oFF" ii dai drumul si apesi pe buton pe rand pana o sa ajungi la ce test vrei tu...



Semnificatia codurilor pentru fiecare test:

- test 1 cu cele 6 afisari indica date despre producator...

1st display: BMW PART NUMBER (6 digits)..................................numărul de identificare BMW
2nd display: CODE NUMBER (5 digits) Internal Coding Plug..........numărul de cod
3rd display: K NUMBER (4 digits)................................................codul K (4cifre)
4th display: CHASSIS NUMBER (5 digits) this is part of your VIN...seria de pe sasiu
5th display: SOFTWARE VERSION (3 digits).................................versiunea softului
6th display: REVISION INDEX (2 digits) Hardware........................indexul reviziilor

- test 2 se refera la tipul motorului...
poate fi 2 pt motoare cu 4 cilindri, 3 pt motoare cu 6 cilindri sau 4 pt motoare cu 8 cilindri;

- test 3 indica numarul de km parcursi de la ultima resetare a Oilservice inspection;

- test 4 undeva am gasit ca e varsta masinii in zile... in alta parte zice ca pt masinile din SUA nu are valoare, iar pt Euro reprezinta numarul de zile de la ultima inspectie (cred ca se refera la cea facuta pe bune la reprezentanta )

- test 5 se refera la un factor de evaluare pt viteza si temperatura motorului... afiseaza n= 0 sau 1 pt viteza si t=0 sau 1 pt temperetura....

NOTĂ: "n0" înseamnă că aţi atins pragul maxim de turaţie al motorului şi "t1" înseamnă ca ai supraîncălzit motorul. Daca iti afiseaza aceste valori, testul respectiv este de fals din cauza problemelor legate de software.

- test 6 se refera la nivelul carburantului din rezervor si la temperatura lichidului de racire... indica niste valori in format hexazecimal care trebuie interpretat astfel:
pt carburant
A (empty)--------- > 0d
End of reserve--- > 37
B------------------- > 54
C------------------- > 90
D------------------ > c4
E (full)-----------> f0

pt temperatura lichidului de racire...
A----------------------> ce
B----------------------> 6d
C----------------------> 5c
D (center)----------> 4f-23
E-----------------------> 1e
F-----------------------> 18

- test 7 afisarea digitala a turatiei motorului;



- test 8 reprezinta viteza de deplasare curenta in km/h;

- test 9 se refera la numarul total de km ai masinii inregistati de EEPROM... daca citesti cu atentie mai jos iti poti da seama daca a fost dat inapoi kilometrajul

"This test step will be used if the manipulation dot is illuminated in the cluster display. This display will show the component with the lower mileage. For example:
Display of 012654 l indicates that the mileage in the internal EEPROM is lower than the mileage stored in the coding plug.
Display of 000325 E indicates that the mileage in external coding plug is lower then the total mileage stored in the internal EEPROM.
Pressing the reset button for 4 seconds will over write the lower mileage with the higher mileage and cancel the manipulation dot. The SI data will also be transferred at the same time."

- test 10 indica daca primeste semnal... de la stanga catre dreapta de la urmatoarele:
0=low 1=high
prima cifra - belt contact, seat belt fastened = 0
a 2a cifra - ignition lock contact, key inserted = 0
a 3a cifra - door contact, door open = 0
a 4a cifra - clock button pressed = 0
a 5a cifra - SI reset = 0, for reset = 0
a 6a cifra - EGS transmission failure = 0

- test 11 se refera la semnalul de iesire pentru (de la stanga la dreapta)
1st - Gong output
2nd - Brake warning lamp
3rd - Low fuel warning lamp
4th - EGA lamp
5th - seat belt lamp
6th - manipulation dot

- test 12 nu este folosit;

- test 13 se refera la codul tarii;

- test 14 se refera lasoftware reset...
"The reset must be carried out if any faults are present that are not plausible before any components are replaced. After the reset, the system will exit the TEST mode and the lock will be reactived"

- test 15 daca tii apasat minim 5 secunde apare "L on" si apoi "oFF" asftel se deblocheaza si poti sa vezi valorile testelor de la 5 la 14...

SUCCES!!!

E36 On-BoardComputer (OBC) Hidden Codes and Tests

Varianta 1

This works on all instrument clusters 1992-1999 E36 - 4
door/coupe/convertible/M3.

Step 1. Press and hold the mileage reset button.

Step 2. Put key into ignition switch and turn to KLR (Ignition switch

position #1)

Your LCD display will show something like this "tESt 01"

Step 3. Once "tESt 01" is shown, let go of reset button and the IC

(Instrument Cluster) will go through

some test cycles. Numbers will be shown and here's what they mean:

1st display: BMW PART NUMBER (6 digits)

2nd display: CODE NUMBER (5 digits) Internal Coding Plug #

3rd display: K NUMBER (4 digits)

4th display: CHASSIS NUMBER (5 digits) this is part of your VIN

5th display: SOFTWARE VERSION (3 digits)

6th display: REVISION INDEX (2 digits) Hardware #

After all 6 displays are finished, an analog gauge test will be performed.

The self-test is canceled by switching the ignition off or to KL-15
(ignition

switch position 2)

IC (instrument cluster) tests 1-15

1995 - 1998 (99) 318ti

1996 - 2000? Z3

1997 - 1999 E36 4dr/coupe/convertible/M3

NOTE:

*Test functions 1-4 are unlocked tests and can be called up at any time for

display.

*Test functions 5-14 are locked and require unlocking the test mode before

they can be displayed.

*Test functions 2-14 can be selected at any time when the cluster is

unlocked, even when vehicle is moving.

*Test function 15 is the lock/unlock function.

Step 1: Press and hold the mileage reset button.

Step 2: Put key into ignition switch and turn to KLR (Ignition switch

position #1)

Your LCD display will show something like this "tESt 01"

Step 3: You will need to unlock the test function first so when the LCD

Display shows "tESt 01," press the reset button till you get to "tESt 15."

Once you're on test 15 press, and hold the reset button for a few seconds

until it displays "off." Now you can cycle through the test features. Here

they are as they follow:

Test 1: Instrument self test

Test 2: Engine Data - This display is an "engine factor" value that is
stored

in the coding plug. The instrument cluster processor uses this factor in

addition to the "TD" signal from the DME control module to process and

display tachometer RPM based on the engine installed. For EXAMPLE:

*ENGINE FACTOR 2 = 4 CYLINDER

*ENGINE FACTOR 3 = 6 CYLINDER

*ENGINE FACTOR 4 = 8 CYLINDER

Test 3: SI elapsed distance - the total mileage in kilometer since the last

reset. Which service is due at the next inspection (OIL SERVICE or
INSPECTION)

Test 4: SI elapsed days - no value for US vehicles. Relates to Euro annual

inspections.

Test 5: SI evaluation factor - for engine speed and temp. thresholds being

passed.

Display: n = 0 or 1. Engine speed (over-rev)

t = 0 or 1. Engine temp.

NOTE: "n0" means that you hit the maximum threshold for engine speed and
"t1"

means you overheated the engine. I found out from my instructor that this

test 5 is false due to software related problems.

Test 6: Fuel Level and coolant temp. - Display of hexadecimal codes in

relation to gauge position.

Fuel gauge ----> Hex value

A (empty)---------> 0d

End of reserve---> 37

B-------------------> 54

C-------------------> 90

D------------------> c4

E (full)-----------> f0

Engine temp. ----- Hex Value

A----------------------> ce

B----------------------> 6d

C----------------------> 5c

D (center)----------> 4f-23

E-----------------------> 1e

F-----------------------> 18

Test 7: Engine speed (Digital Tach)- display of current engine speed

Test 8: Road speed - display of current road speed in km/h

Test 9 Distance reading - this allows the total stored mileage to be updated

if one of the storage components has to be replaced. This test step will be

used if the manipulation dot is illuminated in the cluster display. This

display will show the component with the lower mileage. For example:

Display of 012654 l indicates that the mileage in the internal EEPROM is

lower than the mileage stored in the coding plug.

Display of 000325 E indicates that the mileage in external coding plug is

lower then the total mileage stored in the internal EEPROM.

Pressing the reset button for 4 seconds will over write the lower mileage

with the higher mileage and cancel the manipulation dot. The SI data will

also be transferred at the same time.

Test 10: Status bits (input signals) - the status of digital inputs to the

cluster are displayed as 0 or 1.

Display: 0 = input low, 1 = input high.

_ _ _ _ _ _ <--- Mileage display...6 digits left to right

1st - belt contact, seat belt fastened = 0

2nd - ignition lock contact, key inserted = 0

3rd - door contact, door open = 0

4th - clock button pressed = 0

5th - SI reset = 0, for reset = 0

6th - EGS transmission failure = 0

Test 11: Status Bits (output signals) - the status of digital outputs is

displayed.

Display: 0 = output inactive, 1 = output active

_ _ _ _ _ _ <--- Mileage display...6 digits left to right

1st - Gong output

2nd - Brake warning lamp

3rd - Low fuel warning lamp

4th - EGA lamp

5th - seat belt lamp

6th - manipulation dot

Test 12: not used

Test 13: Country code of cluster - the display indicates the country version

of the cluster. This cannot be

changed in the workshop. Display: USA 02

Test 14: Software Reset - The reset must be carried out if any faults are

present that are not plausible before any components are replaced. After the

reset, the system will exit the TEST mode and the lock

will be reactived.


Varianta 2

E36 On-BoardComputer (OBC) Hidden Codes and Tests

Thereare many interesting functions available on the E36 OBC that are not documentedin the owner's manual, including changing the languageof the display. The procedures described here work on my '97 328iC, which hasthe upgraded OBC - they may work on other models of similar vintage. There aresome links at the bottom of the page for information on other OBCs, and forsetting the language if you don't have the OBC.



Contents:

· Programming the Display Order

· Accessing Data

· Unlock the Display

· Test Codes

· Setting the Country Code



Programming the OBC to Display Contents in a Desired Order

Whenyou repeatedly press in on the turn signal stalk, the OBC display cycles throughthe various information types that it has in memory. The default sequence is:CONSUM1, CONSUM2, EXT. TEMP, SPEED, LIMIT, DIST and TIMER. If you want tochange the display order, use the following procedure:

Pressin and hold the turn stalk for about 5 seconds. The OBC display will change to Prog 1. Press the buttoncorresponding to the first function you would like to have displayed in thesequence. For example, if you would like the outside temperature to bedisplayed first, press the TEMP button. The display will thenchange to Prog2. Continue pressing the OBC buttons in the order you want, upthrough nine entries. You don't have to enter all nine - if you would like thedisplay to cycle only between TEMP and RANGE, simply enter those two items asProg 1 and Prog 2. When finished, press the SET/RES button tostore the sequence in memory.

Torevert to the default order, simply press SET/RES as soon as Prog 1 is displayed.



Accessing Data in the OBC

TheOBC contains a lot of data, and displays the data in a manner determined by thecountry code that is stored in it. The technique to access this data is asfollows:

Press the 1000 and 10 keys simultaneously. You should see Test-Nr.: appear in the display.
The table below lists the available test codes that are available. Enter a test code number, using the number keys, followed by the SET/RES key. However, to access codes other than 1, 10, 14, 19, and 21, you have to first unlock the OBC, using the procedure described below.
Read the results.
For test numbers 10 and 11, enter a new value (if desired) and press SET/RES.
Return to the normal display functions by pressing CHECK or any other key.


Unlock the Display.

Mostof the test sequences require you to first unlock the display before. Entertest code 19 using the above procedure. The display should read LOCK:ON. Then enter an unlocking code consisting of the sum of the currentmonth plus date (for example, if today is July 11, enter 18). Then press SET/RES, and the OBC is nowunlocked.



TestCodes. Following is a listing of the available tests,along with with my notes as to what I think each test means. Note that thedisplay uses European conventions for decimals (i.e., the number 61,7 is 61.7for us Americans). You will see that I don't have good explanations for severalof these test codes -- if you have any information that can help me make thistable more complete, please email me at Ceno@BMWplanet.com

Setting the Country Code.

If your OBC suddenly starts displaying everythingin German, and you would like to put it back to English, use test sequencenumber 10. Once you're into test number 10, press the 1 key several times, andyou'll see the display cycle through various country options. For example, 0is for Germany (the display reads LAND:0 D * - I assume D stands for Deutschland). As you cycle through theoptions, you'll see choices for the Great Britain, USA, France, Canada, etc.Once the display is on the country you want, press the SET/RES key to store yourchoice into memory -- for US drivers the display should be set to LAND: 2 USA * . Then press the CHECK key, and the displaywill reflect the units of the country you've chosen.





Instrument Panel Tests

Withthe engine off, press and hold the trip mileage reset button, and then turn thekey to accessory position 2 (OBC and radio come on). The LED display on theinstrument panel (which normally is the odometer) will change to tESt01 and then will begin to cycle through several displays. Releasethe button. The display will continue to cycle through several displays. Here'sthe data my car displays:
