Where is the diagnostic 16 pin conector on a 2003 grand vitara?

Answer 1

While I do not KNOW specifically where this is on a Grand Vitara, there are 'rules' for OBD-II (onboard diagnostics, version 2), that have been required for cars sold in America since around 1996. (Before then was OBD-I with more non-standard configurations.)

ODB-II designs specify that EITHER of these two configurations are used for the connector:

1. The connector be located underneath the area of the steering wheel column...so look around under the dash on the driver's side to see if the connector is there. (It may have a rubber or plastic cover over it protecting the pins.)

2. If the connector is NOT installed under the area of the steering wheel column, A LABEL MUST BE PUT IN THAT GENERAL AREA SPECIFYING WHERE THE OBD-II CONNECTOR HAS BEEN INSTALLED.

So look around under the dash in the vicinity of the Steering wheel. There SHOULD either be the connector, or a label saying where the connector actually is.

Good Luck!
