Using Code Reader
CODE RETRIEVAL PROCEDURE
If the Code Reader does not turn on automatically when
connected to the vehicle, it indicates that there is no power at
the vehicle's DLC. Check your fuse panel and replace any
burned-out fuses.
If replacing the fuse(s) does not correct the problem, consult
your vehicle's repair manual to locate the proper computer
(PCM) fuse/circuit. Perform any necessary repairs before
continuing.
4. Turn the ignition on. DO NOT start the
engine.
If the ignition key is not turned
"ON" within 10 seconds after
the Code Reader is connected
to a vehicle, an "Error" mes-
sage will show on the Code
Reader's LCD display. At
times, an error message may
display after you turn the
ignition key on. If this happens,
wait for the Code Reader to
automatically re-link to the
vehicle's computer.
After 10-60 seconds, the Code
Reader will retrieve and display any
diagnostic information (trouble
codes, Monitor status) stored in the
vehicle's computer memory.
If the Code Reader does not retrieve vehicle diagnostic
information and keeps cycling between "rEAd" and "Error" on
the LCD display, it indicates that the Code Reader is unable to
communicate with vehicle's computer. Do the following:
- Turn the ignition key off, wait 10 seconds and turn the key
back on to reset the computer.
- Make sure your vehicle is OBD 2 compliant. See VEHICLES
COVERED on page 6 for vehicle compliance verification
information.
If the Code Reader is interrupted or disconnected during
code retrieval procedure, the screen will display "Error".
6. Read and interpret the Diagnostic Trouble Codes using the LCD
display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the LCD
display) as visual aids to make it easier for the user to
determine engine system conditions.
