Paul zocht een handleiding voor zijn OBC.
Op de site staat nog meer.



==============================================================================
Undocumented Features.
These work on OBC II cars:
Simultaneously press the 1000 and the 1 button to get remaining fuel in liters (the car needs to be running).

Simultaneously press the 1000 and the 10 button to get the version number. You should get something like:

4 .6TYP

Where the 4 is the car/engine designator, the 6 is the chip firmware. That tells you the programming of the OBC, what coding plug is in it. Specific to each engine type, injector type, tire size, fuel tank and reserve capacity. And here's some more from Phil Marx.... OBC car/engine designators and firmware number. E30 318i 3-3 TYP
E30 325e ('84-87) 3-8 TYP
E30 325e ('88) 4-4 TYP
E30 325i ('87) 3-1.2 TYP
E30 325i ('88 on) 4-6 TYP
E30 M3 3-1.1 TYP
E28 528e ('85-87) 5-8 TYP
E28 528e ('88) 5-1.3 TYP
E28 535i 5-6 TYP
E28 M5 6-4 TYP
E24 635Csi/L6 ('85-87) 6-2 TYP
E24 635Csi ('88 on) 6-6 TYP
E24 M6 6-4 TYP
E23 735i/L7 ('85-87) 7-4 TYP
For what this bit of knowledge is worth to anyone....... No other test functions on that type OBC but you'd need a book to discuss the E32/4 type.

The following is for newer OBC found in E36 cars for example:
To determine if your OBC is eligible .. press 1000 and 10 together.
you should see TEST NO . -- or something like that.
Now, some of the functions are locked out -- I do NOT recommend messing with them and you do so at your own risk -- that said ...
To unlock all functions .. press 1000 and 10 and at the TEST prompt enter 19 using the keys .. press SET/RES .. you should see LOCK:ON or something similar ... press the DATE key .. (today you'd see 08.20) and add the two numbers (day and month) together (today 28)

Now enter the number you just calculated (28) and press SET/RES. TADA .. you have unlocked the secret functions ...

To lock them back up .. press 1000 and 10 then enter 19, SET/RES now press SET/RES again .. it should show .. LOCK:ON again

In general when I show a test enter it by pressing 1000 and 10 together then enter the number of the test with the numeric keys and press SET/RES to actually execute the test ...
