🔧 What Is This Part?
The Engine Control Module (ECM) — Part No. 33920-68PL3 (33920M68PL3) — is the brain of your Maruti Suzuki K10B engine. Manufactured by Bosch with MOTRONIC platform 0261S19300, this ECU controls fuel injection, ignition timing, idle control, and emissions. Made in India.
⚠️ Faulty ECU Symptoms — Mechanic Verified

- 🐢 No Power to Injectors — Fuel injectors not receiving signal/current from ECU.
- ⛽ No Power to Ignition Coils — Spark plugs not firing due to missing coil current.
- ❄️ A/C Stops Working — ECU controls A/C relay; faulty ECU = no cooling.
- 🌡️ Radiator Fan Not Running — ECU controls fan relay; engine overheats.
- 🚫 Accelerator Pedal No Response — Throttle body not receiving signal.
- 💥 Engine Misfiring — Random or consistent cylinder misfires.
- 📉 Rough Idle / RPM Fluctuation — Unstable idle, hunting RPM.
- ⛽ Poor Fuel Efficiency — Mileage drops significantly.
- 🔇 Engine Stalling — Shuts off while driving or at idle.
