ISSUE
Some vehicles equipped with the 4.0L engine may exhibit a condition of "unable to access" with the SecuriLock Passive Anti-Theft System (PATS). When an operation requiring PATS Security Access is attempted, an error message may be displayed, or a reference to Coded Access may be displayed. It will not be possible to enter Security Access to erase or program ignition keys into the vehicle with this condition present. This may be caused by the calibration of the Powertrain Control Module (PCM).

ACTION
Verify the condition. If normal diagnostics cannot pinpoint the condition, reprogram PCM to the latest level calibration. Refer to the following Service Information for details.

SERVICE PROCEDURE

If the New Generation Star Tester (NGS) or Worldwide Diagnostic System (WDS) displays either of the following error messages when attempting to enter Security Access for the Passive Anti-Theft System (PATS), reprogram the PCM using the NGS or WDS as necessary.

^ WDS: "The test has found a fault" followed by a screen, "Coded Access mode not supported"

^ NGS: "Security Code number: _ _ _ _ _ _ Contact local hotline for access code"
