Diagnostic Aids

This DTC alone does not indicate a fault in the PSCM. It indicates an overtemperature condition due to ambient conditions and/or a heavy load on the EPAS system. A heavy load is defined as multiple parking lot maneuvers over a short duration of time with low tire pressure or towing for long distances followed by multiple parking maneuvers.

The thermistor used by the PSCM is calibrated for 80| C (176| F) and as ambient temperature decreases, so does the accuracy of the sensor. At room temperature and lower, the sensor will be +/- 20| C (68| F).
