Pressing the button next to 14 will show the data for each of the Parameter Identifications Descriptors PIDs if data was captured when the trouble occurred The screen will allow you to step through the PID numbers using the lower left and right buttons and see the available data Gauge values will be shown in the top line for those PIDs which directly correspond to a gauge 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 NOTE Reading the Freeze Data does not clear it This is done when the DTCs are cleared Selecting iL Ak z will make the display show the trouble code For example This example shows a trouble code of i HE1 Since there were 2 stored trouble codes in this example pressing Mi i will show the other trouble code Pressing PEL i again will not Pt change t the display because we are at the last trouble code Pressing FEL LLL will return the display to show the earlier trouble codes Pressing the 1 4 button will result in a prompt from the ScanGaugell to verify that you want to clear the trouble code s and turn off the Check Engine lamp If you want to continue to clear the trouble codes press i If you decide not to Se the trouble codes press When the t button is pressed the ScanGaugell will send out a signal to cl2. The estimate of distance and time to empty is based on the economy that has been obtained so far on this tank of fuel Right after refueling these values will change fairly quickly As more of the fuel has been burned from the tank the readings will stabilize It is possible to see the distance and time to empty increase as you drive The distance can increase as you drive at a steady fuel efficient speed 11 This causes the fuel economy for the tank to rise and applying this higher fuel efficiency to the fuel remaining in the tank can actually result in more remaining distance If you drive slower than the average speed of the tank so far the time to empty can increase You should refill the vehicle when there is above 50 miles km remaining Pushing below 50 could result in running out of fuel ree the lower left button again will return the selection to the BE seat I Continuing to press it will cycle the trips from one to thes next iii Shows different types of information 1 in some cases from the other D EHR substitutes Fii EP rT data in place of i PHa data Pressing Eii from the HOME display will bring up the following display This selection leads to buttons choices which will allow the display backlight intensity to be e changed or or r turned oii Pressing COLOR will cause the backlight color to change in the following sequence WHITE gt USER gt BLUE gt GREEN gt TU
