Overview

STN1170 combines the entire STN1110 (multiprotocol OBD-II) feature set with Single Wire CAN (SW-CAN) and Medium Speed CAN (MS-CAN) protocols in a single 44-pin IC. SW-CAN protocol support allows your device to access, monitor and issue commands on vehicles utilizing GM’s proprietary CAN network. Similarly, MS-CAN provides access to Ford’s proprietary CAN network on supporting models.

On vehicles hosting SW-CAN or MS-CAN networks, our enhanced ST command set allows your device to interpret data not available on the vehicle’s OBD-II bus. Using the GM & Ford proprietary codes, you can commonly interpret current status of systems such as:

  • Seat belt
  • Airbag
  • Headlight
  • Anti-Lock Brake (ABS)
  • Traction Control

Control commands commonly found on supported vehicles include:

  • Door lock/unlock
  • Window up/down
  • Radio volume up/down
  • Turn signals & Hazard on/off
  • Engine start/kill

While STN1170 ST commands will provide access to SW-CAN and MS-CAN networks, the proprietary GM & Ford codes must be obtained independently. A popular method is to join the Equipment and Tool Institute where the codes can be accessed/purchased. Alternately, the traffic can be analyzed and reverse engineered.

Supported Protocols

  • all legislated OBD II protocols:
    • ISO 15765-4 (CAN)
    • ISO 14230-4 (Keyword Protocol 2000)
    • ISO 9141-2 (Asian, European, Chrysler vehicles)
    • SAE J1850 VPW (GM vehicles)
    • SAE J1850 PWM (Ford vehicles)
  • non-legislated OBD protocols:
    • Single Wire CAN (SW-CAN) – GM proprietary network
    • Medium Speed CAN (MS-CAN0 – Ford proprietary network
    • ISO 15765
    • ISO 11898 (raw CAN)
  • SAE J1939 OBD protocol used in heavy-duty vehicles

Features

  • Safe, secure bootloader. Reflash the firmware in the field, even over a poor quality link and avoid expensive product recalls.
  • Fully compatible with ELM327 command set, ensuring out-of-the-box compatibility with the dozens of existing software applications.
  • Extended “ST” command set provides access to enhanced functionality, without compromising compatibility.
  • PowerSave mode with multiple sleep and wakeup triggers. Ideal for permanent in-vehicle setups, device can be left connected for extended periods of time without draining the battery.
  • Perfect form factor for any application. STN1170 is available in TQFP and QFN packages.
  • RoHS compliant
