Professional Installation Required
Must be performed by certified technicians familiar with CAN bus systems.
Incorrect installation can damage the entire electrical network.
Programming Is Mandatory
VIN input
Configuration matching (e.g., 6x4 vs 8x4 drive axle)
Transmission type (AMT/manual)
Cab type (day/sleeper)
New CBCUs often come unprogrammed.
Must be configured using SINOTRUK TechTool, KTS diagnostic devices, or compatible OBD-II scanners.
Programming includes:
Never Open or Modify the Housing
Sealed unit — tampering voids warranty and risks permanent damage.
Internal components are static-sensitive and not user-repairable.
Use Genuine or Remanufactured Units Only
Avoid cheap clones — they lack correct firmware or fail quickly.
Choose OEM or reputable remanufacturers that test functionality.
Disconnect Battery Before Work
Prevents electrical surge and protects sensitive electronics.
Wait at least 10 minutes after disconnection.
Check Ground Connections
Ensure clean, tight grounding points — poor ground causes erratic behavior.
Apply anti-corrosion grease to terminals.
Test All Functions After Installation
Lights (headlights, turn signals, interior lights)
Wipers
Horn
Door locks
Climate controls
Verify operation of:
Use diagnostic tool to check for DTCs.
Avoid Harsh Environments
Protect from excessive moisture, vibration, and extreme temperatures.
Do not install near direct water spray or exhaust heat sources.
Regular Diagnostics Recommended
Run periodic scans using compatible tools to detect early-stage issues.
Clear stored codes only after fixing root cause.
Storage Advice
Keep sealed in anti-static bag until use.
Store in dry, room-temperature environment.
