Problem before entering:

 

I am trying to change mileage on Volvo V50 2004 dash withdigiprog3odometer master clone v4.94.

 

I have downloaded a German version user manual and soldered 3 wires as shown in German manual (checked pin numbers). Adapter 51 has 4 wires. Pin 25 (white on original, or orange on clone) left unsoldered. I’m getting "ERROR INIT” message on screen. Processor is MC9S12DG128B. I selected HCS12 in digiprog 3.

 

What I’m doing wrong? Then I contacted my dealer. Theuobd2.nettechnician helped solve the trouble. It should work for whom hasDP3on this dash.

 

I checked the Volvo V50 HCS12 user manual withdigiprog iiiagain, and noticed that at least 4 wires, vss, vdd, tx and rx should be soldered.

 

I posted the attachment they provided.

The job needs good soldering/ desoldering skill. Lucky, the problem was settled.
