Do's & Dont's (For Service & Maintenance) DO’S - ECU (Electronic Control Unit) DO - Ensure right terminals /connections are made to battery DO - Check for condition of fuses, relay & wiring harness before replacing ECU DO - Always use anti static mat, straps & gloves while handling ECU to avoid electrical overstress (EOS) DO - Tightening torque of mounting screws to be maintained DO - Ensure proper dataset is flashed into the ECU & also ensure proper dataset is selected while flashing into ECU. DO - After mounting ECU, as soon as possible assemble the harness connector DO - Ensure proper grounding / earthing. Ground line of ECU to be free from paints, dust DO - Make sure there are no joints in the cable between PC/laptop and Diagnostic connector DO - Ensure proper grounding / earthing DO - Ground line of ECU to be free from paints DO - Ensure no power interruptions, communication loss during flashing of dataset to ECU. DO’S - Sensor (Engine Speed Sensor) DO - Engine speed sensor must be removed from its packing just prior to installation in the vehicle. DO - Sensor to be mounted by pushing it into place. DO - First support of wire after connection: Max 250 mm. It should be on the sensor carrier. DO - Replace damaged O-Ring. DO - The storage area must be dry, dust-free and within the per missible storage temperature range. DO - Clean and grease O-Ring prior to installation with mineral oil-based grease. DO - Fix with only partially self-sealing cylindrical screw M6X12. DO - Tightening Torque specification should be 8 ± 2 Nm. DO - Storage temperature: -20ºC to 50ºC. DO - Short-term storage temperature: -10ºC to 55ºC at 85% DO’S - Sensor (Accelerator Pedal Sensor) DO - Tightening Torque of the retaining screws should not exceed 9±1.5 Nm DO - Use only self locking screws. DO - After damage or in doubt of damage (e.g. dropped APM) the APM has to be separated and scrapped. 62
