Peugeot 308 owners may be surprised to learn about the existence of hidden diagnostic and configuration menus accessible through cheat codes on the car’s infotainment system. These codes, primarily intended for technicians and engineers, can offer valuable insights into the vehicle’s performance, connectivity, and settings. This article explores the known cheat codes for the Peugeot 308’s SMEG+ system, providing a comprehensive guide to their functions and potential uses.
Unveiling the Secret Codes of SMEG+
Accessing the cheat code mode on the SMEG+ system is simple: press and hold the “Media/Radio” button for an extended period. This action will unlock a hidden menu where you can input specific codes to trigger various functions. Below is a list of known codes and their corresponding effects:
Audio and Bluetooth Controls
- ARKBYP: Activates the Arkamys audio bypass functionality, potentially altering the sound processing.
- AUDIOINFO: Displays detailed information about the audio system settings.
- BT0DB: Generates a constant 0dBm signal at 2441MHz (channel 39) for Bluetooth testing.
- BT;ECHO param1: Adjusts the Bluetooth echo filter, with values ranging from 0 (lowest) to 160 (maximum).
- BT;GAIN param1: Modifies the Bluetooth audio gain from 0 (lowest) to 30 (maximum).
- BT;NOISE param1: Controls the Bluetooth noise filter, with values from 2 (lowest) to 20 (maximum).
- BTADC param1 param2: Alters the ADC value of the Bluetooth signal. The # sign indicates whether to increase (P/6) or decrease (M/7) the value within the range of -54 to +12.
- BTINFO: Shows current Bluetooth settings.
- BTRENAME param1: Changes the Bluetooth device name.
- BTSTARTER param1: Enables (1) or disables (0) the Bluetooth module.
System Diagnostics and Information
- CATCLN: Clears specific configuration data; requires diagnostic tools for reconfiguration.
- CLNMEM: Erases all stored configurations; necessitates the use of diagnostic equipment to restore settings.
- DATA: Accesses critical system data, typically requiring specialized diagnostic tools.
- ECSAVE param1: Turns the ECO mode on (1) or off (0).
- FPS: Displays the Frames Per Second (FPS) meter on the left side of the clock, indicating system performance.
- GPSINFO: Shows GPS satellite information, signal quality, latitude, longitude, and speed.
- GUIDBG: Activates a graphical user interface debugger, primarily for development purposes.
- HWINFO: Reveals hardware information including battery voltage, SMEG+ temperature, fan speed, and free memory.
- REBOOT: Restarts the SMEG+ infotainment system.
- SWINFO: Displays information about the installed software version.
- SYSMON: Shows system monitoring data, such as CPU load, RAM usage, and ROM capacity.
- TUNERINFO: Provides detailed information about the radio tuner.
Network and Connectivity
- MMIMON: Monitors multimedia data streams, likely for debugging purposes.
- NETINFO param1: Displays network connection information and configuration settings.
- PING param1: Sends a ping command to a specified address (e.g., ping 8.8.8.8) to test network connectivity.
Logging and Debugging
- SPYCLN: Clears system logs.
- SPYSTORE: Saves a copy of the system logs to a FAT32 formatted USB drive.
- SPYTAKE: Retrieves logs from a USB drive and restores them to the SMEG+ system.
Proceeding with Caution
While these cheat codes offer intriguing possibilities for exploring your Peugeot 308’s inner workings, it’s crucial to exercise caution. Altering certain settings without proper understanding could potentially lead to unexpected behavior or even system malfunctions. It is strongly recommended to avoid modifying any parameters unless you possess the necessary technical knowledge and understand the potential consequences. These codes are primarily intended for diagnostic and troubleshooting purposes by trained professionals.
