Hi, you will need a scanner to obtain the code for the power cover , ford has a TSB that adresses several things possibly, but without knowing what the code maybe it will be hard to say for sure. See below for the TSB. If you have anymore questions , please let me know thanks
TSB 02-9-2 | - BODY - TONNEAU COVER DIAGNOSTIC AID
|
| Publication Date: APRIL 26, 2002 |
ISSUE:
The tonneau cover may not stay closed (automatically reverses when commanded to close) on some vehicles. This may be caused by either the Pinch Strip or the Rear Latch Switches (latches misaligned), or a combination of both.
ACTION:
Verify condition and check for Diagnostic Trouble Codes (DTC). Refer to the following Diagnostic Procedure to help identify and correct tonneau cover condition.
SERVICE PROCEDURE
Check for DTCs. Possible codes are B2417 (Pinch Strip stuck active) and/or B2422 (Open Switch stuck active), or B2787/B2788 (Latch error codes for the right and left latch respectively).
If both Pinch Strip and Rear Latch codes are retrieved, address the Pinch Strip code first as the Latch codes could be a result of the Pinch Strip concern.
Observe the Pinch Strip PID on WDS or equivalent. If the status does not change, (always active), visually check for a mis-positioned strip (strip out of groove/pulled out of corners). If the strip is not damaged, re-install it, clear codes, and re-test the system. If it is damaged, replace the strip, clear codes and re-test the system.
If just the Rear Latch codes were received or if they are still present after repairing the Pinch Strip, shim the latches as necessary, clear codes and re-test the system.
