If the vehicle uses an Indirect Tire Pressure Monitoring System, the TS601 will not be able to communicate with the vehicle via the OBD port. If available, use one of Autel’s fully bi-directional diagnostic tool such as the MS906 or MS906TS to auto scan the vehicle and confirm the vehicle has a TPMS module.
The tire pressure monitoring system can also be managed by the Body Control module. If one of these modules is present, contact Autel Technical Support to ensure the tool and its associated cable is functioning correctly.
