Modified elm327 interface

[scan]

In replacement for the need to use adapter cable no 3(ELM C19), is it safe to modify an elm327 by linking can pins this way:
6 connected to both 6 and 1 and pin
and
14 connected to both 14 and 9
?


For pin 7 to 12 there is a jumper already.

NO, PLEASE DO NOT DO THIS!!!

The car has 2 different CAN networks (CAN1 on pins 6,14 and CAN2 on pins 1,9). If you connect the pins this way you will make a short circuit between the two networks.... The result from this in most cases will be only a lot of stored errors in each module (which is not critical), but in some very rare cases it could cause electrical damage...

Thank you.

You can make this change between CAN 1 and CAN 2 using a DIP switch directlly into the interface or you can use an external adaptor
Take a look in the attashament
1. its a modified ELM327 with DIP Switch and you can switch pin 6 to pin 1 and pin 14 to pin 9
The other one it is a manual multiplexor where you can switch all k-line used in Fiat/Alfa/Lancia cars ( including the pins that are not used yet in Multiecuscan ) and a switch for CAN .
This both are made by me.
Good luck
