How to use OBD Service Deactivation -Configuring OBD

This module allows users to modify the communication mode of the OBD Dongle. Changing these settings is essential for managing power consumption, ensuring stealth (listen-only), or troubleshooting protocol discovery.

There are four available modes, each tailoring how the stacks and services interact with the vehicle.

Active ModeThe default setting. All services and ObdStacks are fully operational.Standard Operation: Full read/write capabilities and standard data transmission.
All deactivated, no listen onlyOBD, DTC, and ObdStacks are completely disabled.Maximum Restriction: Minimum power draw with zero vehicle interaction.
Activated with Protocol autodetection disabledProtocol autodetection is deactivated, but allows for manual connection configuration using ObdStacks setConnection.Manual Configuration: Used when you need to bypass automatic protocol discovery and set the connection parameters manually.
Full passive mode, with listen onlyObdStacks remain active to allow for listen-only monitoring.Stealth & Conflict Prevention: Silent bus monitoring without data transmission. Required if an OEM connected service (e.g., Mercedes me) is active on the vehicle to prevent dashboard error messages.
Passive mode with active connectionThe OBD service is active only for protocol discovery. RPM requests for ignition simulation are disabled.Troubleshooting: Used when ignition simulation is handled externally by the MDI_OBD_RPM database.
