T-Hammer, the on-board diagnosis (OBD) tool for use in Porsche 928, 944, 968, 964 og 993 models. 1,5m cable with an OBD2-style 16-pin connector.
The T-Hammer gets the power supply from the car battery, and has no internal batteries. No hassle with worn-out and leaky batteries!
For use in the Porsche 928, 968, 964 and 1994-model 993, be sure to include a 19-pin adapter, sold separately.
Some 928 and late 944-models has an OBD possibility and require a 12-pin adapter.

Important information
The T-Hammer does not support all OBD-functions in 1996-1998 Porsche 993 models. Some of the in-car control units in these (Tiptronic, DME, ABS/ABD, Airbag) can be unavailable or even interrupt/disturb the usage of the tool.
Some 993-models are equipped with a 996 Airbag control unit. This was standard fitment in most late models (1996/1997/1998), but also in earlier vehicles where the control unit has been replaced. The T-Hammer is not compatible with 996 control units.
The Porsche 964 Carrera 2 has an ABS control unit without an OBD-interface. Only the 964 Carrera 4 ABS/PDAS control unit has OBD diagnostic capability.
The T-Hammer might be incompatible with special/rare versions of the Motronic engine control unit, typically GT- or turbo models. We also often see that aftermarket modified engine control unit "chips" disturbs, or even makes OBD connection impossible.
The usage of the T-Hammer is described in the Porsche Workshop Manuals, but we have gathered the most important inforation on our Downloads page.
