UltraGauge is compatible with most* 1996 and newer foreign and domestic vehicles sold in the United States.  While OBD II compliance was federally mandated in 1996, some vehicle makes and models were compliant as early as 1994.  Compliance is indicated on the vehicle's emissions decal located in the engine compartment.  Below are examples of emission decals.

Please confirm that your vehicle is OBDII certified.  UltraGauge is only compatible with vehicles which are OBDII certified.  While OBDII compliance was mandated in the USA in 1996, this is not true internationally.  Most countries eventually did adopt the OBDII standard. However, vehicles sold prior to OBDII adoption may or may not be OBDII compliant. For example, Australia did not adopt the OBDII until 2006. However, many pre-2006 vehicles are compliant, many are not.

J1850 VPM Early GM & Chrysler
Ford Early Ford
9141 Early Chrysler and Foreign
KWP 2000 Rare, various
