ISSUE
Some 2003 Expeditions built 4/1/2002-1/31/2003, 2003-2005 Town Car and 2003-2006 Lincoln LS, and Navigator vehicles may exhibit an inoperative parking aid system and diagnostic trouble code (DTC) C1983 stored in memory of the Parking Aid Module (PAM).
ACTION
Follow the Service Procedure steps to verify the vehicle has DTC C1983 in memory. If DTC C1983 is the only DTC present, it may be necessary to replace the PAM.
NOTE
IF THE VEHICLE ALREADY HAS THE LATEST LEVEL PAM MODULE (REFERENCING THE PART NUMBERS LISTED IN THIS TSB) AND C1983 IS THE ONLY DTC PRESENT, CONTINUE WITH NORMAL DIAGNOSTICS IN THE APPROPRIATE WORKSHOP MANUAL.
SERVICE PROCEDURE
1. Use the IDS to run PAM self-test.
2. If DTC C1983 is the only code present, replace the PAM referring to the physical replacement procedure in the on-line Workshop Manual (WSM). If other codes are present, repair other DTCs before continuing with this TSB.
Refer to the following for the correct WSM section:
^ Expedition/Navigator/Town Car: Section 413-13
^ Lincoln LS: Section 413-00
3. Reprogram the PAM using the following procedure:
a. Start vehicle and place transmission gear selector into Reverse (R), wait a minimum of 10 seconds.
b. Shift the gear selector into Drive (D), drive the vehicle ABOVE 25 MPH (40 Km/h) for a minimum of 15 seconds.
c. Stop the vehicle and cycle the key off, then back on.
d. Repeat Steps a, b, and C, three (3) more times for a total of four (4) times.
NOTE
THE IDS NOW HAS THE CAPABILITY TO CHECK THE PIDS FOR THE RADAR SENSORS. USE THESE PIDS TO VERIFY OPERATION OF THE TWO (2) RADAR SENSORS.
