SPMS v1.1.1 is stable and fully configured per requirements. Enable production data sync and MFA before go-live.
Chery’s SPMS (Scalable Powertrain Management System) V1.1.1 represents a mid-level iteration in the brand’s hybrid and electric vehicle control software. This paper provides a structured guide to setting up SPMS V1.1.1, focusing on its unique parameter hierarchy, CAN signal mapping, and safety interlock configuration. We present a step-by-step setup protocol, highlight common pitfalls, and compare V1.1.1 with earlier versions. The aim is to serve as a practical reference for test engineers and calibration specialists working on Chery’s Fulwin and eQ series platforms.
Locate the Chery_SPMS_v1.1.1_Setup package. It usually comes in an ISO, RAR, or ZIP format. Extract the files to a dedicated folder on your desktop. Do not run the setup directly from a compressed archive. chery spms v1 1 1 setup

Key change in V1.1.1: Decoupled torque security path – two independent microcontrollers compare torque requests before enabling inverter gate drive. Proceed to User Acceptance Testing (UAT)
After the software installation completes, the setup moves to the validation phase. This is not optional. The technician runs the "Dry Cycle Test" —feeding synthetic VINs through the system to confirm that when a virtual car passes an antenna reader, the SPMS dashboard updates within the specified 200ms latency window.
A hallmark of a successful V1.1.1 setup is the calibration of the Andon Board Integration. The legacy Chery Andon systems (visual/audio alerts for line stops) must be linked via a digital I/O relay. The setup utility includes a "Pulse Test" that flashes the workshop lights and sounds a chime. Only when the physical light corresponds to the virtual alert is the setup deemed operational.

| Issue | Likely cause | Fix | |-------|--------------|-----| | ECU not entering READY | HVIL open or BMS timeout | Bypass HVIL with 120Ω resistor | | Torque oscillation at low speed | Resolver offset incorrect | Re-measure using oscilloscope | | DTC P1B23 (checksum error) | Config tool version mismatch | Reflash with DiagPro, not 3rd-party tool | | CAN ID conflict | Duplicate IDs on bus | Remap using gateway configuration |
