U0462Invalid Data Received From Compass Module
- Generic OBD-II code · Network
- How the car detects it
- The compass module measures the earth's magnetic field, usually with two perpendicular sensors in the interior mirror or overhead console, and sends the heading to a display or navigation unit. Gentex patented a mirror compass of this kind with automatic calibration, compensation for magnetic disturbances inside the car and a link to the vehicle bus. U0462 is set when the receiving unit, for instance the instrument cluster, still gets compass messages but rejects them, for example because a counter or checksum fails or a value lies outside the possible range; if the messages stop, U0161 applies. No manufacturer documents U0462 publicly. The heading may show dashes or jump about; recalibration after a magnetic disturbance or a battery change sometimes helps. Driving is not affected and no MIL lights.
