Invalid Data Received from Cruise Control Front Distance Range Sensor
ACC receives bus messages from the radar but their content is implausible (e.g. negative distances, jittering targets). Adaptive cruise is disabled until the radar reports plausible data again.
Affected components
- Acc radar
Common causes
- High likelihood: Radar obstructed by snow/dirt
- Medium likelihood: Radar misaligned after collision
- 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
- The malfunction indicator lamp may illuminate
