3. Operating Instructions

3.1 Key Programming Functions

The MUCAR KEY581 offers advanced key programming capabilities:

• Immobilizer Matching: This function electronically binds the key chip with the vehicle's Immobilizer system (such as the ECU) through authentication, ensuring that only authorized keys can start the vehicle.

• Remote Cloning: This feature copies the wireless signal of an existing remote control directly to a new remote, allowing the new remote to fully perform all original functions (e.g., unlocking, car locating).

Figure 5: Remote Cloning Function

• Remote Generation: This function creates or copies the wireless signal of a vehicle remote control, enabling remote operations such as door unlocking and trunk access.

Figure 6: Remote Generation Interface

• Chip Read & Clone & Write:
  • Read Chip: Gives you access to basic information pertaining to the key, including chip type, IMMO type, transponder ID, locking status, and code mode.
  • Clone Chip: Used to directly clone and generate a functional chip for your vehicle, saving the trouble of using the old OBD approach.
  • Write Chip: Allows you to choose an IMMO type (accessible via the transponder reading function) and edit it according to your needs.

• Key Frequency Detection: Detects the frequency of car keys.
• Ignition Coil Detection: Detects the status of the ignition coil.

3.2 OBD2 Diagnostic Functions

The MUCAR KEY581 provides comprehensive OBD2 diagnostic capabilities, offering all-in-one solutions for vehicle health monitoring:

Figure 8: OBD2 Diagnostic and Reset Functions Overview

• Data Stream (Mode 1): Retrieves and displays live data and parameters from the vehicle's ECU.
• I/M Readiness (Mode 1): Indicates if all emissions components have been evaluated by the OBD II system.
• Display Freeze Frame (Mode 2): Records certain vehicle conditions when an emission-related fault occurs.
• Read Codes (Mode 3): Identifies which part of the Engine emission control system has malfunctioned.
• Clear Codes (Mode 4): Erases diagnostic trouble codes (DTCs) from the vehicle after repairs. Ensure the ignition is ON and engine is OFF before clearing codes.
• O2 Sensor Test (Mode 5): Displays results of the ECU's last O2 sensor test. Note that not all test values are applicable to all vehicles.
• On-board monitor Test (Mode 6): Reads results of on-board diagnostic monitoring tests for specific components/systems.
• EVAP System Test (Mode 8): Initiates a leak test for the vehicle's EVAP system. The tool signals the vehicle's computer to start the test. Refer to your vehicle's service manual for specific procedures.
• Vehicle Information (Mode 9): Displays vehicle information such as VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number).
• Turn off MIL (Malfunction Indicator Lights): Resets the Malfunction Indicator Light after issues are resolved.

3.3 Hot Reset Maintenance Functions

The device supports 9 critical maintenance reset functions:

Figure 9: 9 Hot Special Functions

• Oil Lamp Reset Service: Resets the Engine Oil Life system after an oil change.
• EPB Service: Essential for the maintenance of electronic braking system's safety and efficiency.
• BAT Battery Service: Evaluates battery charge state, monitors close-circuit current, registers battery replacement, and activates the rest state of the vehicle.
• Throttle Adaptation: Re-learns the throttle sensor position after clearing or repair, crucial for electronically fuel-injected cars.
• Injector Coding: Addresses issues with leaking or dead injectors that might not be detected otherwise.
• SAS Service: Clears fault steering angle sensor memories and assists in steering angle sensor calibration.
• Gear Learning: Monitors camshaft position sensor signals to ensure conditions are met for engine running procedures.
• Gearbox (Transmission) Reset: Resets Transmission Adaptive Learning. After performing this, the Engine Control Unit (ECU) and Transmission Control Unit (TCU) will learn your driving pattern.
• AFS Headlamp Reset: Resets the Adaptive Front lighting System (AFS) to keep headlights pointing straight ahead, preventing them from turning with the steering wheel.

3.4 Read Voltage & Leakage Current Detection

This function is specifically designed for leakage and voltage detection of remote controls. It should not be used for other products.

• Leakage detection: Detects current leakage in the remote. Supports a current range of 1 microamp to 35 milliampere. (Do not insert battery into remote during this test).
• Voltage detection: Detects the voltage of the remote battery. Supports a voltage range of 0V-36V.
