Innovate Motorsports OT-2 - Manual (Page 17)

Standard Trouble Codes are listed both with a number and a description. Manufacturer specific
codes will generally just appear as a number, though sometimes, like the case above, the general
category can be identified.
You can request that the ECU clear the pending codes using the Clear and Refresh button at the
bottom right corner of the page.
Note: On some vehicles, the ignition must be on, but the vehicle not started, for the Clear DTC
request to be accepted.
Note: Pressing the ‘Clear and Refresh’ button sends a request to the ECU that all trouble codes
be cleared. But, ultimately, the ECU decides if a code can be cleared. If the same failure
conditions are detected, the light will stay on and some codes can only be cleared by a series of
special steps or special vendor specific commands.
4.5 Updating Firmware
Updating the firmware requires you to connect the OT-2 to the computer via the USB cable.
On the ‘Info’ tab of the LM programmer software you will find a button to ‘Update Firmware.’ Click
it. You will be presented with a file dialog box that allows you to select a firmware file. Firmware
files end with the file extension .dld. OT-2 firmware file names start with: ot2b. The first part is
followed by the version.
After you opened the firmware file, this new firmware will be downloaded in the DL-32 device
