Hi , i have problem with 4WD Hyundai IX 35

But i measure on coil i have 2,5oHms.
But when i measure volts on coil pins nothing go here from 4WD computer
I make diag on 4wd computer but no fault , nothing,

Can be bad 4wd computer not sending power to coil?

Possible 4WD module is protecting 4WD clucth as temp is too high,

before changing clutch, you need to check following,
-max difference 2.0 mm in tyre tread depth between all tyres
-compare all 4 ABS sensor while driving
-make sure no comm faults in 4WD module (U CODES)
-check connection to 4wd clutch 12V PWM Signal
