Freelander td4 2000 reg Three Amigo's ON

Hi I have a Freelander TD4 2000 reg, that had been standing for 4 years, I have fixed quite many things to put it back on road, viz, alternator, all belts, full service, new clutch plates, pressure cleaned the breaking & clutch system, one new ABS ring, but it still has the three light on the dashboard (three Amigo's). I got it tested with computer and got following results as in the pic below. I am not sure where to start now, could it be the front ABS sensors need replacing or since its been sitting for 4 years that I need to take out the ABS unit to check?
Would appreciate if someone can put me in the right direction.....
Thanks

Left and right front abs sensons need looking at.....the other faults could just be from a flat battery

I recently returned to life a 1998 that had been standing 18 months had to change front sensors and rings and repair HDC switch on gear lever

I have checked and serviced the the HDC Switch it seems ok
I have also replaced a working one from another freelander, still have three amigo's, so HDC switch is not the issue in this case....
Can any one advice how I can test if the ABS sensors are ok?

Get a multimeter and test the resistance of each sensor look between 950-1100ish

If u do find a sensor faulty replace the ring while your there as there only a few £ each then u no the corner has been replaced

Try pushing the left one in a little..the right one needs replacing. Acording to you error scan logs....but at around 20 quid's each by 2 new uns

How do I push it in as its all rusty and doesnt budge?
