E-shifter problem
No error 44. Shifter doesn't move. Replaced 2 shot resistors, but problem persists. Gear indication on the matrix display jumps from correct gear to 4th and back when wheel turned. Motor drive has voltage on in1 (5v), but nothing on in2. It has voltage on VBB (16.7v), but nothing on VREF. All resistors are working. Hall sensors seem working. What else should I check?
