If communication with the ECU is faulty and normal monitoring is not possible, check the below points and restart SMARTASSIST-Direct.
If the communication cable disconnects or the power supply to the ECU/product is interrupted during data transmission, the system may not operate normally even after a restart. In that case, turn off the power (with the key switch)
