Manufacturer summary

Original wording in English

Some vehicles may exhibit that, after using the cabin preconditioning, when starting the engine, the CHECK ENGINE light illuminates with DTC P0531:00 (Refrigerant pressure sensor No.1 system: Function malfunction) stored in memory. NOTE: If the cabin preconditioning was not used, this TSB is not applicable. (DTC P0531:00 concern without using the cabin preconditioning is under investigation.) This is caused by improper control logic of the PCM. To eliminate this concern, the control logic of the PCM has been modified.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
