Keyless/Power Door Locks/Security System Symptom Troubleshooting - AUTO DOOR UNLOCK does not work

NOTE: 

• Refer to the Electrical Wiring Diagrams for the location of the under-dash fuse/relay box connectors.
• Before testing, check the No. B8 (15 A), No. B9 (15 A), No. B15 (10 A), No. B30 (10 A), No. B32 (15 A), No. B33 (15 A), and No. B41 (20 A) fuses in the under-dash fuse/relay box.
• There are two pairs of fuses in the same circuit (No. B8 and No. B32 fuses, No. B9 and No. B33 fuses, No. B15 and No. B30 fuses). If one fuse is blown, make sure to check the other fuse in the same circuit. If necessary, replace the blown fuse(s).
