Diagnostic Aids

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

This DTC alone does not indicate a fault in the PSCM. It indicates an over-temperature 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).

The presence of DTC B1D23:68 will prevent the active park assist system (if equipped) from activating. If set during an active park assist event, the event will be terminated and the active park assist system will deactivate.
