AUTO DOOR UNLOCK Does Not Work (2015-17)

NOTE: 

• Before testing, make sure the No. A2-3 (60 A) and No. A29 (10 A) fuses in the under-hood fuse/relay box are OK.
• Check if Auto Door Unlock feature selected OFF, under MID customized settings for each remote transmitter: Driver 1 & 2.

  Make sure to test operation of each Auto Door Unlock setting to check function.

• Before testing, make sure the No. B1 (7.5 A), B5 (7.5 A), B19 (10 A), B20 (10 A), B21 (10 A), B22 (10 A), B23 (10 A), B32 (20 A), B33 (20 A), No. B41 (10 A), and No. B42 (20 A) fuses in the under-dash fuse/relay box are OK.
• There are two pairs of fuses in the same circuit (No. B21 and No. B23 fuses, No. B19 and No. B22 fuses, No. B20 and No. B41 fuses). If one fuse is blown, make sure to check the other fuse in the same circuit. If necessary, replace the blown fuse (s).
