Check Engine
Get Trouble Codes
The last known trouble codes can be viewed from the UltraGauge application without being connected to the Adapter (Android
only). This can be achieved as long a vehicle is first selected. In order to clear trouble codes and view pending trouble codes
from the vehicle, the engine does not need to be running, but the ignition must be in the RUN position and it must stay in this
position.
This screen allows you to view/clear the check engine light, and view current/pending trouble codes. By selecting the icon in the
title bar, the Readiness screen can be accessed.
Trouble Codes:
Displays the total number of trouble codes (up to 20) followed by a list of the specific trouble codes with a summary
description of the trouble code. Each trouble code is prefixed by a letter, as shown in the table.
The four numeric digits following the letter prefix uniquely identify the code.
Each manufacturer may choose to define codes differently and even differently
among vehicle models.
The date when the trouble code was first seen by the Application is also displayed.
This may provide an indication as to when this problem may have first occurred.
The
symbol can be pressed to search on the internet for the specific trouble
code. In the example above, clicking on the WWW symbol would bring up a web page on your mobile device with the
following search:
http://www.dtcsearch.com\P0100
For additional information, the best approach to further decode a trouble code is to search the internet. For example, search
for “2004 Dodge Durango P1002 Trouble code”. There are several sites dedicated to providing trouble code information.
Here are a few sample sites:

Clear Check Engine Light:
This not only turns off the check engine light, it also clears all the Trouble Codes.
Note that if the trouble code was associated with a hard fault, such as a shorted
sensor, the vehicle’s ECU will quickly repost the trouble code to pending codes,
or in some cases directly to trouble codes and again light the check engine light.
In this situation, it may appear that the check engine light remains lit.
Note: Some vehicles may not support this function. Vehicles supporting the
VPM protocol such as older GM vehicles and some older Chrysler vehicles
have been found not to support this function.
Pending Trouble Codes:
Displays the number of pending trouble codes along with the codes themselves
(up to 20). Pending codes are potential issues discovered by the Vehicle’s ECU.
These discovered issues are placed in the pending category and watched by the
ECU. If the issue persists after a certain amount of time or after a certain number
of starts, the ECU will move the code from Pending to the Trouble Code category,
at which point the check engine light would be lit.
The format and meaning of Pending Codes is the same as that for Trouble Codes.
See Engine Trouble Codes for additional detail.
