4. Setup and Initial Connection
4.1 Connecting the Device to Your Vehicle
The MUCAR CS90 connects to your vehicle via the OBDII port, also known as the Data Link Connector (DLC). This is a standard 16-pin port where diagnostic tools interface with the vehicle's onboard computer.
- Locating the DLC: In most vehicles, the DLC is typically found within 12 inches (approximately 30 cm) of the center of the dashboard, usually under or around the driver's side.
- Alternative Locations: If the connector is not under the dashboard, a label might indicate its location. In some Asian and European vehicles, the DLC may be located behind the ashtray, which might need to be removed for access.
- Guidance: If you cannot locate the DLC, refer to your vehicle's service manual for specific guidance.

- Mode 6: System Monitoring: Retrieves results of on-board diagnostic monitoring tests for specific components/systems.
- Mode 7: Read Pending DTCs: Displays diagnostic trouble codes detected during the current or last driving cycle that are not yet confirmed.
- Mode 8: Control Operation of On-Board System: Allows control of on-board system components or tests.
- Mode 9: Read Vehicle Information: Retrieves vehicle information such as VIN, Calibration ID (CALID), and Calibration Verification Number (CVN).
- Mode 10: Request Emissions-Related Diagnostic Trouble Codes with Permanent Status: Requests emissions-related DTCs with permanent status after a clear/reset of emission-related diagnostic information.

5.3 Maintenance Services (28 Reset Functions)
The Maintenance menu provides access to 28 commonly used maintenance and reset functions to assist with regular vehicle upkeep. These services are crucial for maintaining vehicle performance and safety:
- Oil Lamp Reset Service: Allows you to perform reset for a new calculation of Engine Oil Life system once changed the oil.
- EPB Electronic Park Brake Reset: It is important in the maintenance of electronic braking system's safety and efficiency.
- BAT Battery Service: Allows the scan tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, and activate the rest state of the vehicle.
- DPF Diesel Particulate Filter Reset: Specially works for Diesel Particulate Filter system with DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit.
- SAS Steering Angle Sensor Reset: Helps clear the fault steering angle sensor memories and plays an important role in the steering angle sensor calibration.

- Sunroof Reset: The sunroof needs to be reset when the sunroof control unit have communication problem or changed.
- Suspension Reset: Try reset electronic suspension air ride with the massage system close all doors koeo flip through messages system go to suspension reset or on off.
- Gearbox (Transmission) Reset: Procedure Reset Transmission Adaptive Learning DIY. Start the car and drive. Once you perform this procedure the Engine Control Unit (ECU) and Transmission Control Unit (TCU) will work together to learn how you drive by monitoring your driving pattern. After you follow this programming method of the TCU / ECU drive the car.
- AFS Headlamp Reset: 'AFS' means Adaptive Front lighting System (at night with the Bi-Xenon headlights) it swivels either side, pressing that button means they stay pointing straight ahead and don't turn when you turn the steering wheel.
- Injector Coding: Leaking injectors and some dead injectors can be missed even when an injector is disabled. Other problems with the ignition system and mechanical components also may not show an rpm loss when an injector is turned off.
- Throttle Adaptation: The throttle body is a tube containing a pivoting flat valve (butterfly) that is used to control the amount of air entering an engine. In an electronically fuel injected car, a throttle position sensor and air flow sensor communicate with the computer, which supplies the corresponding amount of fuel needed at the injectors. It must need re-learning throttle sensor position after clearing or repair.
- Gear Learning: The scan tool monitors certain camshaft position sensors signals to determine if all conditions are met to continue with the procedure for Engine running.
- EGR Reset: Reduce nitrogen oxides (NOx) in the exhaust gas and improve fuel economy at partial load.
- A/F Reset: This function is applied to set or learn Air/Fuel ratio parameters.
- Adblue Reset (Diesel Engine Exhaust Gas Filter): After the diesel exhaust treatment fluid (car urea) is replaced or filled up, urea reset operation is required.

- AT Learning: This function can complete the gearbox self-learning to improve gear shifting quality. When the gearbox is disassembled or repaired (after some of the car battery is powered off), it will lead to shift delay or impact problem. In this case, this function needs to be done so that the gearbox can automatically compensate according to the driving conditions so as to achieve more comfortable and better shift.
- Language Change: This function is used to change the system language of the vehicle central control panel.
- Nox Sensor Reset: Nox sensor is a sensor used to detect the content of nitrogen oxides (Nox) in engine exhaust. If the Nox fault is re-initialized and the Nox catalytic converter is replaced, it is necessary to reset the catalytic converter learned value stored in the engine Ecu.
- ODO Reset: a) ODO reset is to copy, write, or rewrite the value of kilometers in the chip of odometer by using a car diagnostic computer and data cable, so that the odometer shows the actual mileage. b) Usually when the mileage is not correct due to the damaged vehicle speed sensor or odometer failure, it is necessary to do ODO reset after maintenance.
- Stop/Start Reset: This function is used to open or close the automatic start-stop function via setting the hidden function in ECU (provided that the vehicle has a hidden function and supported by hardware).
- Seat Calibration: This function is applied to match the seats with memory function that are replaced and repaired.
- Transport Mode: In order to reduce power consumption, the following functions may be disabled, including limiting the vehicle speed, not waking up the door opening network, and disabling the remote control key, etc. At this time, the transport mode needs to be deactivated to restore the vehicle to normal.
- Windows Calibration: This feature is designed to perform door window matching to recover ECU initial memory, and recover the automatic ascending and descending function of power window.
