Question
How do vehicle manufacturers implement TPMS protocols differently?
Answer
Each uses proprietary communication rules (burst timing, checksum, security) to prevent tampering.
Explain
Toyota uses 8-byte ID packets with CRC checksum; Ford uses 6-byte IDs with rolling codes; GM adds encryption for security. CHEPQ tools decode 200+ OEM protocols, enabling universal service without brand-specific tools.
