What to Do if DTCs Are Found

If you your vehicle’s Check Engine light is on, that’s a good indication that your vehicle may be storing

Trouble Codes (DTCs). If ScanGauge indicated it has found stored DTCs, you can access the specific

code numbers and related Parameter Identification Descriptors (PIDs), also known as Freeze Data, if

data was captured when the trouble occurred.

Viewing DTCs

To view the specific DTCs, press the function

button next to CODES. If more then one code

is stored, you can use the lower left and right

function buttons to step through the stored

codes.

Viewing PIDs

To step through and view the available PID data,

press the lower left and right function buttons.

Gauge values will be shown in the top line for those

PIDs that directly correspond to a gauge (see pages

24 and 25 for Gauge Abbreviations).

The values in the second line are in hexadecimal

just as they are reported by the vehicle computer.

You can exit this mode using the HOME button.

2 STORED CODES

If there are any stored DTCs, ScanGauge will display

the number of stored DTCs. Use the lower left function

button next to CODES to see the DTCs. Use the lower

right function button next to FRZD, to view PIDs.

If No Codes Are Found

If no codes are found, ScanGauge will display

NO CODES FOUND on the first line. The left

side of the second line will display either READY

or NOT READY.

READY - Indicates all tests have been completed since the last reset. This is needed in some states to

indicate a valid OBD test for emission testing.

NOT READY - Indicates the vehicle hasn’t completed some test cycles. It could take up to several

days after codes are cleared for the vehicle to be READY, and your vehicle may not pass some types

of emissions testing.
