If the ABS/EPS-BAS warning lights are on, then fault codes are stored in the ABS module that may help to diagnose the root problem. We need these fault codes first before suggesting the next course of action. You will need to use an advanced scan tool like StarScan/StarMobile/ WiTech or equivalent to acces fault codes and tests. Diagnosis first!
All 4 wheel speed sensors failing at the same time would be very unlikely. Were there fault codes for these?
A short road test with the following should re-initialize the ABS/ESP:
NOTE: For Sensor Signal and Pump Motor faults, the ABM must sense all 4 wheels at 12 km/h (7.5 mph) before it will extinguish the ABS indicator.
NOTE: If the ABM (Anti-Lock Brake Module), SAS (Steering Angle Sensor), Dynamics Sensor was replaced, it must be initialized using the scan tool. If not initialized, the ABS indicator will flash continuously with no DTCs. To initialize the ABM and clear offsets have wheels pointing straight ahead and follow the directions on the scan tool. The drive test requires a 90° turn and turning wheel from lock to lock. If the Dynamics Sensor was replaced, test drive the vehicle by turning the vehicle left or right in a curving manner at a velocity between 10 and 25 km/h (6 and 15 mph).
The NAV may need the ABS/ESP to be active for vehicle speed and vector information, so this may be a related problem.
