Keyless/Power Door Locks/Security System Symptom Troubleshooting - AUTO DOOR UNLOCK does not work
AUTO DOOR UNLOCK does not work
NOTE:
Before testing, make sure the No. A1-5 (30 A)*2, No. A2-2 (30 A)*2/(50 A)*1, and No. A18 (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: Driver 1 & 2.
Make sure to test operation of each Auto Door Unlock setting to check function.
Before testing, make sure the No. B8 (15 A)*3/(20 A)*4, No. B9 (10 A), No. B12 (10 A), No. B13 (10 A), No. B15 (20 A), No. B16 (20 A), No. B25 (10 A), No. B26 (10 A), No. B28 (20 A), No. B38 (10 A), and No. B39 (10 A) fuses in the under-dash fuse/relay box are OK.
There are two pairs of fuses in the same circuit (No. B25 and No. B39 fuses, No. B12 and No. B26 fuses, No. B13 and No. B38 fuses, No. B38 and No. B39 fuses). If one fuse is blown, make sure to check the other fuse in the same circuit. If necessary, replace the blown fuse(s).
