(solved) Vocom + Tech Tool view DTCs of MACK truck

This is customer feedback about how to solve Vocom + Tech Tool view DTCs of MACK truck Not compatible.

I’m have a MACK to read faults, but unluckily I failed to diagnose (view DTC’s) or use any off the other features of my Tech Tool 2.04.87. PTT says the software is incompatible and that version on the control unit(s) is not supported by Tech Tool.

Here is my version info:

Product: Tech Tool
Version: 2.04.87
Database: Standard

Every time I go to view DTC’s I get these errors :
it says: the version of software installed in the engine and vehicle electronic control units are incompatible. Electrical faults will present in one or both modules. Upgrade the software in one or both modules to correct the problem.

then i Click OK and get this one:

Software on the control unit(s) below is not supported by Tech Tool.

Please update Tech Tool and try again.

Then ask obdexpress for help.. solved my issue

I am advised to update the firmware of 88890300 Vocom Interface. Just follow the screen message to do that. Then tech tool works like a charm.
