BYD Song and Han series vehicles have a huge market presence. From the early fuel-powered and first-generation DM models, they have evolved into the current DM-i, DM-p, EV, Han L and Song L new models, featuring numerous variants and vastly different configurations. Many repair technicians have encountered headaches: even within the Song or Han lineups, hardware differs among Champion Edition, Honor Edition and Intelligent Driving Edition. When repairing electrical systems and troubleshooting tri-power faults, using documentation for the wrong model year can easily lead to misdiagnosis.

Whether performing engine overhaul, resolving chassis abnormal noises, conducting high-voltage battery testing, troubleshooting controller faults, or disassembling dashboards, door panels and sunroofs, service manuals and circuit diagrams matching the exact model year are essential. High-voltage tri-power work must never rely solely on experience; standardized reference materials are the prerequisite for safe repairs.

The Auto Helper Database integrates complete repair resources for the full 2015–2026 Song and Han families, covering fuel, plug-in hybrid and all-electric variants.
