2. Check the resistance between the ADAS control unit 2 terminals.

   ADAS control unit 2		Resistance (Ω)
   Terminal No.
   8	28	Approx. 108 – 132

3. Check the resistance between the side radar front RH terminals.

   Side radar front RH		Resistance (Ω)
   Terminal No.
   1	2	Approx. 108 – 132

Is the measurement value within the specification?
