1. This auto scanner (OBD II car reader) easily connects to the
diagnostic socket and will quickly find your trouble issues by
reading the specific diagnostic trouble codes (DTC) and shows their
description as well.
2. Moreover, this tool can display live data from your car's
computer, such as current RPM, engine coolant temperature, vehicle
speed, oxygen sensor data, and much more.
2. U485 Instructions:
1. OBDII connector cable, connect car and the scan tool.

1. Does My Car Have OBD-II?
All cars and light trucks built and sold in the United States after
January 1, 1996 were required to be OBD II equipped. In general,
this means all 1996 model year cars and light trucks are compliant,
even if built in late 1995.
Two factors will show if your vehicle is definitely OBD II
1) There will be an OBD II connector located under or around the
2) There will be a note on a sticker or nameplate under the hood:
"OBD II compliant".
2. Where is the connector located?
The connector must be located within three feet of the driver and
must not require any tools to be revealed. Look under the dash and
3. The Three Flavors of OBD II:
While the parameters, or readings, required by OBD II regulations
are uniform, the auto manufacturers had some latitude in the
communications protocol they used to transmit those readings to
Naturally, each felt they had the one true way, so we have three
different OBD II communications protocols in use.
4. What Communications Protocol does my vehicle use?
As a rule of thumb, cars and light trucks use SAE J1850 VPW
(Variable Pulse Width Modulation). Chrysler products and all
European and most Asian imports use ISO 9141 circuitry. Fords use
SAE J1850 PWM (Pulse Width Modulation) communication patterns.
There are some variations among captive imports such as the Catera,
a German Opel derivative, which uses the European ISO 9141
5. On 1996 and later vehicles, you can tell which protocol is used
by examining the OBD II connector:
J1850 VPW-The connector should have metallic contacts in pins 2, 4,
5, and 16, but not 10.
ISO 9141-2--The connector should have metallic contacts in pins 4,
5, 7, 15, and 16.
J1850 PWM--The connector should have metallic contacts in pins 2,
4, 5, 10, and 16.
