Trouble Shooting
Should users encounter problems with the EFILive software, FlashScan or
AutoCal hardware
they should:
1.
Confirm software, firmware and boot block versions are up to date.
2.
Check the fitment of the SGM Bypass cable (required for 2018+ vehicles).
3.
Check RSA Digital Signature has been removed (required for all 2009+
vehicles).
4.
Check that checksums are valid.
5.
Check the base file matches the calibration for your vehicle.
6.
Check Dodge Cummins Fast CAN Mode settings.
7.
Only CMB and CMC stock files can be read from the ECM.
8.
CSP
5
tune files cannot be read from the ECM.
9. Remove/isolate all after-market devices including mobile phone adapters, after-
market equipment (audio systems, security, remote start etc.) and any devices
wired into the OBD port that may interfere with vehicle communications.
10. DO NOT operate any vehicle feature that may communicate on the data bus.
This includes opening or closing of hood, doors, windows, as well as changing
settings on radio, HVAC, connecting/removing charging devices etc.
Error Codes
If an error occurs while using AutoCal, users can look up the error code
description in the EFILive V8 Scan and Tune software.
The [F8: Tools] -> [F8: Error Codes] menu item provides an error code lookup
function, and the
“EFILive Error Codes.pdf” document accessed by selecting the
Windows Start Icon and navigating to Program Files->EFILive->V8->Documents-
>EFILive Error Codes.pdf is also available. Both options provide error code
descriptions, causes and actions.
Should the issue not be resolved after reviewing the Error code list, end users
should contact their Tuner for support.
Checksums
Checksums perform a vital role in ensuring the integrity of the data in the tune file.
There are two main reasons that checksums display as invalid:
1. The data in the file is corrupt and MUST NOT be flashed into a controller.
2. The data in the file has been modified with a software package that did not
update the checksums
– such as a hex editor.
Do not correct the checksums unless you know the tune file was modified outside
of the EFILive software and that the modifications are correct and accurate.
If you correct the checksums of a file with corrupt data you are merely masking
corruption. If you flash a corrupt file into a controller, you risk damaging the
controller and/or causing the vehicle to operate incorrectly.
