My work is my life ART TECH GARAGE
AT commands for FORD ELM327 CAN pin selection mod
programmable parameter 2A only available from ELM327 1.3 or upper firmware version (edit: this is not true, also available for ELM327 v1.2a)
edit: updated picture
edit: AT command to show current programmable parameters: atpps
example:
>atpps
atpps
00:FF F 01:FF F 02:FF F 03:32 F means off (disabled), N means on (enabled)
04:01 F 05:FF F 06:F1 F 07:09 F
08:FF F 09:00 F 0A:0A F 0B:FF F
0C:68 F 0D:0D F 0E:FF F 0F:FF F
10:0D F 11:00 F 12:FF F 13:32 F
14:FF F 15:FF F 16:FF F 17:92 F

28:FF F 29:FF F 2A:38 F 2B:02 F
2C:E0 F 2D:04 F 2E:80 F 2F:0A F
to set all to defaults: atd
to disable all parameters (set them off): atppffoff
(note that these two commands don't revert programmable parameters to default values, even after reset or power off/on, you got to set them to default values by hand, see default values in the picture above)
SAY THANKS!!

Might be worth adding pin 15 to the rotary switch K to L (with a make or break) it is used quite a lot on A CLASS mercs for example instruments ect.

Pin 11 is always transmission on mercs & pin 13 on EEC5 for reprogramming, they do a 12 to 1 rotary switch so it would be ideal to keep all options open
naser (24th March, 2013)
it's ok, so then use a 1P12T rotary switch instead, we can add 4 more posibilities for k line like this:
1 -> fiat abs
3 -> fiat airbag, opel eps + immo
7 -> all engine, fiat automatic gearbox
8 -> bmw ?, fiat immo
9 -> fiat eps + climatonic
11 -> mb transmission, fiat alarm + lock doors
12 -> opel airbag + abs, fiat engine bay wiring
13 -> EEC5 reprogramming, fiat rear wiring
15 -> mb class A instruments
empty
empty
empty
please help complete pin features depending on car makes:
2 -> any make not as sae j1850+ but as k line?
6 -> any make not as can high but as k line?
10 -> any make not as sae j1850- but as k line?
14 -> any make not as can high but as k line?
this is 1p12t rotary switch
this is dpdt switch
i forgot to include a knob

Some early vauxhalls approx 1997 used pin 6 for engine ecu but not at 10400 baud , and early saab's used pin 14 without pin 6 but no idea what for

Hello, I own a 1998 Mercedes A Class, it seems to me this thread is about switches for k-lines using elm327.
The 1998 A Class w168 uses many pins for k-lines. Here's a scheme:
Pins 1, 7, 8, 11, 12, 13 and 15 are all used for klines. The cheap elm327 bluetooth adapter from china only uses pin 7 and all obd software doesn't work.
Can you suggest a solution? Switches for k-lines? I saw this post about a mod for Fiat that doesn't use switches but resistors: http://www.cardiagnostics.be/-now/Fi...ne_adapter.htm
Do you think this solution could also work for thew A Class. What about the pin 3 TNA Gasoline ? Is that used to check ignition?
Thanks
don't know about mercedes pinout and protocols, i can't help, try and tell?

Hello, thanks for your reply. The protocol should be iso 9141-2, the pinouts is as in the scheme I posted.
In your scheme you put also two switches for CAN, right? I don't think I need those for MB.
I only need to access k-lines but maybe I am not getting the functionality of those switches.
Could you advise?
Thanks
A class merc's use the kw2000 fast init protocol up to approx. 2004 bc ( before can )
set elm ( SP5 )
Hi, are you sure? What does 'set elm sp5' mean? Scan protocol number 5?
Anyway I see obd iso 9141-2 and kwp2000 share the same pins. The point is multiplexed k-lines and switches between them.
