OBD Manual OEM Request Validation Instruction
Revision as of 12:29, 4 June 2026 by Maynard.castro (talk | contribs)
This guide outlines the procedure for manual OEM request validation using the obdoemdatasource: command. This process is used to manage and verify data sources when the device retrieves multiple or incorrect diagnostic values.
Recommended firmware 04.02.00.rev.602+
When to Use
- Incorrect Values: When an OEM parameter value is wrong due to incorrect validation.
- No Value: When no OEM parameter value is received by the device.
- Erratic Data: When a source (e.g., OEM Ignition) provides sporadic data that does not correspond to the actual vehicle state.

The command can be executed through various communication channels:

Step-by-Step Validation Examples
Example 1: Locking Total Mileage to a Correct Source
