At DQ Car Care, we understand that as vehicles age and run longer, wear and tear can lead to both electrical and mechanical problems. Issues may arise from heavy usage, rough handling, or accidental damage—but with the right expertise, most electrical faults can be diagnosed and repaired or replaced quickly and effectively.
Modern cars are built with advanced electrical and electronic systems integrated into mechanical components. These include ABS (Anti-Lock Braking System), EPS (Electric Power Steering), EPB (Electronic Parking Brake), TPMS (Tire Pressure Monitoring System), throttle position sensors, crankshaft and camshaft sensors, steering torque sensors, MAP and MAF sensors, oxygen sensors, electronic throttle controls, transponder keys, immobilizers, and ECM-controlled fuel injectors.
Our trained technicians use advanced diagnostic tools to identify issues accurately and provide reliable solutions. Whether it’s repairing electronic modules or replacing faulty wiring and sensors, DQ Car Care ensures your car’s electrical systems are restored to optimal performance for a safe and smooth drive.
As vehicles accumulate mileage, various electrical and electronic systems may start to fail due to wear or minor damage. In most modern cars, issues like hard starting, poor pickup, or overheating are often caused by faulty sensors or control modules—not the ECM itself. Since ECMs are costly, a proper diagnosis is essential before replacing anything. DQ Car Care uses advanced scanning tools to detect faults in systems such as ABS, EPS, TPMS and various engine sensors. Our diagnostic equipment reads DTC codes and helps us accurately find and fix the exact problem.
ECM / ECU DIAGNOSIS & REPAIR
The ECM monitors and controls key functions such as fuel injection and ignition timing using input from various sensors. Faulty or unstable sensor input can directly affect its performance. At DQ Car Care, we can diagnose, recalibrate, repair and reprogram ECMs using specialised equipment. Our trained technicians ensure that the module is handled safely and repaired correctly — without unnecessary replacements.
SENSORS
Modern vehicles depend on sensors to manage vital functions like fuel injection, ignition timing, emissions, transmission, and throttle control. In many advanced models, including Toyota and Nissan, the ECM and TPS handle throttle response without a physical cable. For smooth performance, these sensors must always deliver accurate inputs. At DQ Car Care, we use advanced diagnostic tools to detect faulty sensors, repair wiring, recalibrate systems, or replace components. Our skilled service ensures your car remains safe, reliable, and efficient on every drive.
INSTRUMENT CLUSTER
Instrument cluster serves as the central display panel, providing the driver with essential real-time information about the vehicle’s performance and condition. Modern vehicles now use fully digital clusters instead of older mechanical ones. Like all electronics, issues can occur, such as faulty readings, dim displays, or warning light failures. At DQ Car Care, we diagnose and repair these problems through recalibration, sensor fixes, or part replacements. Our expertise ensures your dashboard stays accurate and dependable for safe driving.
FUEL & TEMPERATURE GAUGE
Modern vehicles often experience issues with fuel and temperature gauges due to faulty sensors, wiring, or the instrument cluster. The fuel gauge depends on a sensor in the tank, which may need repair or replacement if readings are inaccurate. Likewise, the temperature gauge uses an engine sensor to monitor coolant levels and can malfunction over time. At DQ Car Care, we perform detailed diagnostics to find the exact fault. Our expert solutions restore accurate readings, ensuring safe and worry-free driving.
ODO METER & RPM METER
Today’s cars feature digital odometers and RPM meters powered by speed sensors instead of older cable systems. When sensors fail or lose calibration, the dashboard may display incorrect values. These errors can affect both accuracy and driving safety. At DQ Car Care, we use advanced tools to recalibrate, repair, or replace faulty components. With our expertise, your odometer, speedometer, and RPM meter will deliver reliable, precise readings every time.
ALTERNATOR REPAIR
The alternator is responsible for charging the battery while the vehicle is running. When the alternator becomes weak or fails, the battery voltage drops and warning lights may appear on the dashboard. If the battery warning lamp stays on after starting the car, it indicates that the alternator is not charging. In such cases, bring your vehicle to DQ Car Care — we test, repair or replace faulty alternators to prevent unexpected breakdowns.
POWER WINDOW / GLASS WINDER & MOTOR
Power windows rely on an electrical motor and winding unit to lift and lower the glass. Faulty switches, damaged wiring or failed motors can stop the windows from moving. We repair the winder mechanism, motors, switches and control wiring to ensure smooth and reliable operation.
AUTOMATIC SIDE WINDOW / DOOR GLASS SYSTEM
Automatic door glass systems in modern cars use multi-directional motors, electronic modules and switches linked with the ECM. If the glass moves slowly or gets stuck, our technicians inspect the mechanism and repair or replace the defective components to restore proper functionality.
COOLING FAN MOTORS
The radiator cooling fan activates when the engine temperature rises above normal. If the fan motor fails, the engine will overheat and may suffer serious damage. Our technicians repair or replace cooling fan motors, temperature relays and related wiring to ensure proper cooling and safe operation.
SELF-STARTER MOTOR SERVICE
A worn starter motor often causes starting trouble. Instead of replacing the entire unit, we inspect and rebuild the starter motor by replacing brushes, bearings, solenoid switches and other internal components. This approach restores normal performance at a much lower cost than a full replacement.
