16-00722020-12-07. Service bulletin. STEERING. For 2005-2012 Crown Victoria, 2005-2011 Grand Marquis and Town Car vehicles, Regional Program 13R01 applies to vehicles not registered in corrosion states and not included in Safety Recall 13S08, where operation in high corrosion areas for an extended period may lead to corrosion in the lower intermediate steering shaft swing link. This may result in a compressed upper intermediate steering shaft and separation from the steering column, which can result in a loss of steering control. Vehicles covered under 13R01 that were inspected or repaired without replacement of the lower intermediate shaft, and have relocated to high corrosion areas, may experience subsequent corrosion of the lower intermediate steering shaft swing link.

The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
