DTC B1D23: Overheat Sensor: Action

DIAGNOSE any other PSCM DTCs before diagnosing DTC B1D23:4B. If no other DTCs are present, ADVISE the customer that high ambient temperatures or heavy loads on the EPAS system cause this DTC to set, resulting in higher than usual steering effort. 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.
