U0430 Invalid Data Received From Tire Pressure Monitor Module
U0430 means that a receiver gets frames from the tire pressure monitor module but rejects what they contain, such as wheel pressures, sensor identifiers or a system status outside the permitted range, or a broken message counter. A stand-alone evaluation unit exists for example in the 2020 Jeep Gladiator Rubicon, whose TPM module FCA reflashed to add the selectable tire fill alert (bulletin 08-023-20). No manufacturer documents U0430 publicly with thresholds or a named receiver. FMVSS 138 obliges the TPMS malfunction telltale to light within 20 minutes of a fault that disturbs how the system creates or transmits its signals, so a lit warning lamp and missing pressure readings are the usual result. U0127 is lost contact, U0330 a software mismatch.
Likely causes
Symptoms
- TPMS malfunction lamp on or flashing
- Tire pressures missing or shown as dashes in the cluster
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
