Invalid Data Received From V2X Module

A receiving module detected implausible data from the V2X (vehicle-to-everything) communication module. Position, V2V/V2I message content or signal-quality flags fail plausibility checks and are rejected.

Affected components

  • V2x module

Common causes

  • High likelihood: Module internal fault or sensor input drift
  • Medium likelihood: Software version mismatch after replacement
  • Low likelihood: Gateway module routing CAN messages incorrectly

Possible symptoms

  • Multiple warning lights may illuminate
  • Affected modules may go into limp mode or shut down
  • Specific functions inoperative depending on module
  • Diagnostic tools may show communication faults

Diagnostic notes

  • A drive cycle may be required after repair
