Bus Service 405 serves Choa Chu Kang cemetery, crematorium and columbarium with connections to Boon Lay Bus Interchange and MRT station. This service has two u-turn points, one at the end of Old Choa Chu Kang Road, and the other spanning the width of Lim Chu Kang Road, just before Murai Farmway.

As a special ad-hoc service, it operates only during Qing Ming, Good Friday, First Ramadan, Hari Raya Puasa, Hari Raya Haji, Deepavali and All Souls' Day. Exact operating dates will be released by SBS Transit closer to the first day of operations every year.
During certain operating days with exceptionally high traffic at Old Choa Chu Kang Road, buses may be diverted to skip Old Choa Chu Kang Road entirely, looping at Lim Chu Kang Road and returning back to Boon Lay.

During the Singapore SEA Games 2015, a temporary route variant Service 405M was introduced to bring convenience for commuters to go to the National Shooting Centre located at Old Choa Chu Kang Rd End.
