I have a Ford Escape 2020 titanium hybrid. I replaced the front left headlight (Full Led) with the same part number as the original aftermarket headlight. After the replacement, everything works fine, with all bulbs lighting as needed. but the left-turning light in the car's interior started flashing rapidly. I also got the B1947:01 diagnostic error code. How do I fix this problem? May be help change lump main block?

 

Make sure the plug for that left lamp is all the way on.

If the replacement bulb is not exactly the same as the one it is replacing, you could come up with the problem you have.

 

Swap the left and right bulb and test again. So it's the right side after the swap?

If the LED bulb is not compatible you can try:
1) replace 2 (not just 1) canbus bulbs
2) buy CF15 flasher relay
Just get those on Amazon with free return, keep the item if you like it.

As for the B1947:01 just check with ford dealership your warranty might cover that.
