Help first job monday morning a 2003 peugeot 206, no front wipers, washers. Plugged in using pp2000, no faults in comms unit, no faults in bsi unit. Live data on comms unit recognises all functions of wiper stalks. Go to bsi unit, bsi unit isnt recognising any movement of front wiper stalk, but i can drive wipers fast speed and washers diagnostically from pp2000 but they only operate for a few seconds and dont return to park till driven twice. So is it comms unit or bsi? or something else please help.
