Code meaning and manufacturer information

Original wording in English · Historical directory labels; manufacturer applicability has not been established for every entry.

SCP (J1850) Invalid or Missing Data for Tires

Can I keep driving?

A code alone cannot establish whether driving is safe. A flashing malfunction light, severe shaking, overheating, oil-pressure warning or loss of braking or steering needs prompt attention. Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
