HOST AUTO PRODUCTS Product Lines We Repair
Our engineers are trained on the full HOST AUTO PRODUCTS product range. Below are the major product families we service.
Engine Control Units (ECU)
HOST ECUs manage fuel injection, ignition timing, and emission control for petrol and diesel engines. Common repair issues include firmware corruption, burnt power driver stages, sensor signal processing failures, and thermal management failures in underhood environments.
Transmission Control Modules (TCM)
HOST TCMs govern automatic and manual transmission shift logic, torque converter lockup, and adaptive learning. Failures include solenoid drive circuit faults, CAN communication loss, and EEPROM corruption affecting shift quality and limp-home mode.
Body Control Modules (BCM)
HOST BCMs handle lighting, climate control, window motors, and comfort functions. Repair challenges include multiplex network faults, relay driver burnouts, CAN transceiver failures, and water ingress in door/roof mounted variants.
Sensor Interface Boards (SIB)
Standalone PCBs conditioning signals from oxygen sensors, mass air flow, throttle position, and pressure transducers. Common defects include input protection diode failures, signal conditioning IC burnout, and thermal drift in analogue circuits.
Industrial Automation Controllers (IAC)
HOST IACs manage plant-floor machinery timing, motor soft-start functions, and relay logic automation for light assembly and manufacturing equipment. Failures stem from noisy industrial power supplies, inadequate EMI filtering, and relay weld damage.

Common HOST AUTO PRODUCTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOST AUTO PRODUCTS equipment arriving at our workshop.
- ✓ECU fuel injector driver circuit burnout — HOST ECUs use high-current push-pull MOSFET drivers to energise fuel injectors. Inductive kick, reversed battery polarity during jump-start, or shorted injector windings can destroy the gate driver IC and power transistors, triggering injector fault codes and limp mode.
- ✓TCM CAN bus communication loss and limp shift — HOST TCMs communicate with engine ECUs and ABS modules via CAN protocol. Corrosion in connector pins, CAN transceiver IC failure, or software corruption on the CAN interface layer causes redundant transmission mode and jerky shifts, triggering transmission fault codes.
- ✓BCM multiplex network short and door lock malfunction — HOST BCMs manage door lock solenoids and window motors on a CAN or LIN multiplex bus. Water ingress through door seals or manufacturing defects in solenoid connectors create short circuits, causing the BCM watchdog to disable all door functions and illuminate malfunction lamps.
- ✓Oxygen sensor signal conditioning failure and rich/lean codes — HOST sensor interface boards convert the 0-1V oxygen sensor signal into engine ECU logic levels. Input stage capacitors fail due to underhood vibration, or the precision amplifier IC drifts in calibration, causing false rich/lean signals and increased emissions and fuel consumption.
- ✓IAC relay contact weld and automation freeze — HOST industrial automation controllers drive relay coils in noisy plant environments. Lack of freewheeling diodes, high inductive transients, or arc welding nearby causes relay contacts to stick closed, freezing automation sequences and requiring manual machine shutdown until relay replacement.
- ✓HOST firmware CRC error and ECU brick state — Incomplete OTA updates, electrostatic discharge during servicing, or EEPROM wear-out can corrupt HOST ECU firmware, causing a cyclic reboot or permanent 'brick' state where no engine functions are available and no code reader can communicate.

Frequently Asked Questions — HOST AUTO PRODUCTS Repairs
Do you repair HOST Auto Products ECU and control modules across India?+
Yes. Synchronics repairs the complete HOST Auto Products range — engine control units, transmission modules, body controllers, sensor interface boards, and automation controllers. We offer pan-India pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and 100+ smaller cities, with all repairs performed at our 180+ engineer facility in Vadodara, Gujarat. Typical TAT is 5-7 working days.
Can you fix HOST ECU firmware corruption and brick states?+
Absolutely. Synchronics uses JTAG, ISP, and proprietary HOST programming interfaces to recover bricked ECUs. We validate firmware integrity against factory CRC checksums, reflash with authentic HOST software, and test on advanced ECU test benches. Even units that failed to boot are typically recovered to full functionality within 2-3 days.
What is the typical repair cost and warranty for HOST modules?+
Repair costs depend on failure type — typically Rs. 3000-12,000 for sensor boards, Rs. 8000-18,000 for TCMs/BCMs, and Rs. 10,000-22,000 for complex ECUs. All repairs include 12 months parts warranty covering component failure. We also offer OEM replacement modules at competitive rates if repair is uneconomical.
Do you support HOST Auto Products OEM warranty and dealership repairs?+
Yes. Synchronics is an authorised repair partner for OEM dealerships and Tier-1 suppliers across India. We maintain HOST factory software authenticity, perform detailed test protocols, and provide comprehensive repair documentation and warranty tracking compatible with dealer management systems.
Can Synchronics diagnose HOST module faults using customer fault codes?+
Absolutely. Provide fault codes (e.g., P0101, U0101, U0410) and symptoms, and our engineers will diagnose the root cause and provide a repair quote within 24 hours. Many faults (CAN communication loss, sensor failures, software corruption) can be diagnosed remotely before module shipment to Vadodara.
How do I send my HOST AUTO PRODUCTS unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HOST AUTO PRODUCTS drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HOST AUTO PRODUCTS repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HOST AUTO PRODUCTS unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
