Keyless/Power Door Locks/Security System Symptom Troubleshooting - AUTO DOOR UNLOCK does not work (2018 2019 2020 2021 2022 2023 2024)

NOTE: 

• Check if Auto Door Unlock feature selected OFF, under MID customized settings for each remote transmitter: Driver 1 and 2. Make sure to test operation of each Auto Door Unlock setting to check function.
• Before testing, make sure the No. D1-2 (50 A) and No. D1-5 (50 A) fuses in the fuse holder are OK.
• Before testing, make sure the No. F1 (10 A) fuse in fuse/relay holder B is OK.
• Before testing, make sure the No. C10 (10 A), No. C11 (10 A), No. C12 (10 A), No. C13 (10 A), No. C14 (10 A), No. C26 (10 A), and No. C38 (20 A) fuses in the under-dash fuse/relay box are OK.
• There are two pairs of fuses in the same circuit (No. C10 and No. C26 fuses, No. C12 and No. C13 fuses, No. C11 and No. C14 fuses). If one fuse is blown, make sure to check the other fuse in the same circuit. If necessary, replace the blown fuse (s).
