Connector Usage
Important information when selecting the proper Connector
Automobile manufacturers often will
PHASE-IN
different connectors or communication protocols over a period
of several years. This
PHASE-IN
can
happen during production runs as well as between model years.
Because of the complexity of models and years this practice has caused, this is a
guide
only.
You should refer to the manufacturer’s service information for complete connector usage information.
A few rules of thumb
If the car has an OEM-style connector (which is included in the X431) and an OBD-II connector, the OEM-style
will usually provide the most capabilities for accessing OEM data.
Current examples are:
Mercedes 38
located within or next to the fuse panels in the cowl area
BMW 20
located in the engine compartment, has a screw on cover
Subaru 9
located under left side instrument panel
Kia 20
located by fuse panel under left side of instrument panel
Mazda 17
located under hood usually close to the cowl
Nissan 14+16
located in fuse panel left side of instrument panel
Mitsubishi/Hyundai 12+16
located under left side instrument panel
Toyota/Lexus 17
located next to fuse panel under left side instrument panel
2.
If the car has
only
an OBD-II connector, that connector will usually provide both OEM and generic (OBD-II)
capabilities.
3.
In many cases the Canbus II connector can be used when the selection calls for an OBD II-16c or a Canbus
connector (see Canbus guidelines)

Canbus Guidelines
1.
If the vehicle side of the 16 pin DCL has a female pin in the
#6 and #14
pin positions, the vehicle is a Canbus
vehicle
2.
Canbus usage has been
PHASED-IN
since 1998.
3.
Year model overlap indicated in the connector guide might require trying both connectors listed
4.
All light duty vehicles sold in the US in 2008 are Canbus compatible
5.
A Canbus II connector can communicate with a non-Canbus system in many cases, only Canbus connectors can
communicate with Canbus systems.
6.
The Canbus II replaces the Canbus and Volvo Canbus connectors
7.
The Canbus II can be flash upgraded, the current version as of 9/2008 is 2.2. The download is available online.
The tutorial is available online and on our CD distributed by our Authorized Distributors.
VW/Audi with Aftermarket Radios
!WARNING!
Many VW/Audi factory installed radios are able to communicate with the X431 and factory scanner.
If an aftermarket radio has been installed, the installer might have incorrectly wired the communication wire
to 12V, this is VERY common
If any scanner is connected to to the 16pin diagnostic connector shown below it can damage the scanner, the
radio does not need to be on or communication with the radio attempted for the damage to occur.
If the radio has been incorrectly installed, communication with any module on the vehicle will not be possible.
Verify the radio is installed correctly by checking voltage from pin 4 to pin 7,
IT SHOULD BE 9V OR LESS
If it is not DO NOT CONNECT A SCANNER OR ANY OTHER DEVICE TO THE CONNECTOR.
The radio will need to disconnected or the wiring repaired.
This fault will not effect the operation of the vehicle but it will prevent any communication and damage
scanners connected to the diagnostic connector.
2000 – 2001 Golf, Jetta and Beetle Airbag Module fault
!WARNING!
Do not scan Airbag Module P/N 6Q0-909-605-A used in these vehicles.
Scanning this module will cause the Airbag light to illuminate and it cannot be turned off.
The Airbag module will need to be replaced and recoded if this happens
See the bulletins for these issues and other helpful information on our CD available through our Authorized
Distributors.
