Diagnostic Link Connector And Location - Actron OBD II AutoScanner CP9135 Instructions Manual

The AutoScanner may ask a question which requires a YES or NO
response from the user. Press either the YES key or NO key when the
condition arises.

2.3 Diagnostic Link Connector and Location

The AutoScanner communicates with
the vehicle's computer modules via a
Diagnostic Link Connector (DLC).
OBD II regulations define the physical
and electrical specification for the DLC. Certain
pins in the connector are dedicated for power and
ground. The DLC is also referred to as a J1962 connector. The term J1962
is taken from a physical and electrical specification number assigned by
SAE (Society of Automotive Engineers). The standard ensures that all
vehicles with OBD II systems use the same connector.
The J1962 specification
defines the location of the
DLC in the vehicle. The DLC
should be located under the
dashboard on the driver side
of the vehicle. If the DLC is
not located under the
dashboard as stated, a
decal describing its location
should be attached to the
dashboard in the area the
DLC should have been
located.
