While there isn't a single "scholarly paper" specifically dedicated only to the 17c61 ECU pinout

The Bosch EDC17C61 is a common Engine Control Unit (ECU) used primarily in commercial and passenger vehicles from Mahindra, including the Supro, Jeeto, and some 1.5D and 2.5 CRDI models. 17c61 ecu pinout

  • Power & grounds
  • Switched ignition and main relay control
  • Sensor inputs (analogue): MAP/MAF, TPS, IAT, ECT, O2 sensors (narrowband/wideband), knock
  • Sensor inputs (digital/pulse): Crankshaft position (CKP), Camshaft position (CMP), Vehicle speed (VSS)
  • Actuator outputs (low current): injectors drivers (low‑side), fuel pump relay control, idle air control (IAC) / stepper/servo or PWM valve
  • Ignition outputs: coil driver(s) or ignition module control, high‑current outputs often via external igniter
  • Emissions/heater circuits: heated O2 sensor heaters, EGR control solenoid, EVAP purge solenoid
  • HVAC / idle adaptations: AC input, neutral/start signals, clutch/torque converter lockup
  • Diagnostics and communications: K‑line, J1850, CAN (if later variant), TTL/RS232 debug pins, serial programming (SPI / MICROWIRE / HCS)
  • Miscellaneous: immobilizer/antitheft input, limp‑home indicators, reserved/test pins

The Bosch EDC17C61 is a high-performance diesel engine control unit common in vehicles like Mahindra (1.5d and 2.5 CRDI models). Understanding its pinout is essential for bench-mode programming, diagnostic testing, and ECU repair. Core Bench-Mode Pinout (Infineon TC1724) While there isn't a single "scholarly paper" specifically
