Default Truth about the HEC Diag Mode...

There is a persistent belief that the DTCs displayed by via the HEC (Hybrid Electronic Cluster) diagnostic mode are powertrain related codes, same as those available via a scan tool and the OBD2 port.

It is no one's fault for believing this, as many websites continue to put forth the notion--nonetheless the truth is that they are NOT. Click here to find out more about the HEC diagnostic mode (and the false oil pressure switch failure error it reports).

The bottom line is that the DTCs displayed by the HEC diagnostic mode are only those related to the instrument cluster's operation, mostly body (Bnnnn) and chassis (Cnnnn) codes. In fact, most of the information provided by the HEC diag mode is of little routine use, except perhaps as entertainment...
