Action
DIAGNOSE any other power steering control module (PSCM) DTCs before diagnosing DTC B1D23:68. If no other DTCs are present, INSPECT the electronic power assist steering (EPAS) gear heat shield. INSTALL new as necessary. ADVISE the customer that high ambient temperatures and/or heavy loads on the EPAS system will 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.
