The Nissan Path

Hi I have recently purchased a Multiscan MS509 OBDII coder reader and am unable to get it to connect with my 2002 Pathfinder. I have checked it on the Mrs;s Mazda and it will connect, Can anyone shed some light on this please?
Cheers

Hard to say if it is an issue with your scanner or with the ECM communication. You could try contacting your scan tool's customer support. I would try to see if I could get codes manually. Refer to the "Accessing-Mode 2" instructions at the following link:

Nissan Vehicles (old mostly 2000+) equipped with 16 pin OBDII connecter use Consult II protocol over K line (DDL2) for reading data, so normal connections that most of the software make is on ISO9141 protocol (as both protocols work on the same pin#7).
To connect requires a Bluetooth adapter that utilities the ELM327 chip(Available in market) for communication and Nissan software to send special Nissan connection commands (Available free for lite use).So it connects and gives data on andrioid device.
Make sure to use ELM 327 adapter with version 1.4 or 1.5 as some fake chinies adapters do not work( i bought 2 they didnt work but third i bought made from a good company worked-Pathfinder 2003).
