Causes

  • Faulty or failing TPMS module
  • Faulty TPMS sensor(s) (weak battery, corrupted ID, or bad data)
  • CAN/LIN wiring problems, loose connectors, poor ground, or short
  • Bus communication errors (terminator fault, high/low CAN voltage)
  • Software/configuration mismatch after module replacement or update
  • Radio frequency interference or aftermarket device interference

Symptoms

  • TPMS warning lamp or message on instrument cluster
  • Incorrect, missing, or rapidly changing tire pressure readings
  • Intermittent TPMS warnings that clear after key cycle or re-learn
  • Related drivability or stability control warnings if other modules ignore TPMS data
  • No communication with TPMS module when scanned

What to check

  • Read all stored freeze frame data and related U-codes with a capable scan tool
  • Verify ignition state and that the TPMS lamp/message pattern matches DTC
  • Scan the network to confirm TPMS module presence and check message frequency
  • Inspect TPMS module connectors and wiring for damage, corrosion, or loose pins
  • Check TPMS module supply voltage and ground at the connector (reference vehicle spec)
  • Monitor TPMS CAN/LIN messages for framing errors, checksum/CRC failures, or invalid payloads

Signal parameters

  • Message ID and CAN DLC for TPMS messages
  • Byte fields: sensor ID, tire pressure, temperature, status flags, CRC/Checksum
  • Message frequency (expected interval between TPMS broadcasts)
  • Voltage on CAN high and CAN low lines (dominant/recessive levels)
  • TPMS sensor battery voltage (if provided in payload) or RF signal strength
  • Module supply voltage and ground continuity

Diagnostic algorithm

  1. Record DTC, freeze frame and any accompanying U- or B- codes. Note when lamp illuminated.
  2. Verify TPMS warning behavior during key cycles. Attempt an ignition cycle to see if the DTC returns.
  3. Use a diagnostic tool to list TPMS sensor IDs and live data. Look for missing sensors, invalid IDs, or out-of-range pressures/temps.
  4. Inspect TPMS module connector and wiring for physical damage, corrosion, or poor ground. Wiggle test while monitoring communication for intermittent faults.
  5. Check module power and ground with a multimeter against vehicle specifications. Repair any supply/ground faults.
  6. Monitor CAN/LIN traffic with a scope or capable scan tool. Look for corrupted frames, incorrect voltages, or missing termination.
  7. If a single sensor is flagged, verify sensor battery and replace that sensor, then perform TPMS re-learn and re-check for U0430.
  8. If messages are corrupted or format is wrong and wiring is good, attempt reprogramming/configuration of the TPMS module or restore proper calibration level (use OEM procedures).
  9. If invalid data continues after wiring, power, and reprogramming are confirmed good, replace the TPMS module and re-check entire system and perform relearn procedure.
  10. After repairs, clear codes and road test to confirm the DTC does not return and TPMS readings are stable and plausible.

Likely causes

  • TPMS module transmitting corrupted messages (module hardware or firmware fault)
  • One or more TPMS sensors sending implausible pressure/temperature or invalid ID
  • Damaged wiring harness, poor connector, or corrosion on the TPMS module connector
  • CAN bus termination or voltage fault preventing proper message framing
  • Incorrect module coding or incompatible replacement module

Fault status

⚠️ Status
Invalid data received from Tire Pressure Monitor Module — message failed validation (CRC/check, wrong format, out-of-range values, or unexpected ID).
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
