DTC U0159: Lost Communication With Parking Assist Control Module A: Description

WARNING: This page is about a different car, the 2014 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The parking assist control module is integrated into the PAM.

The PSCM will monitor the HS-CAN bus when the ignition has been on for more than 5 seconds, when the voltage to the PSCM is greater than 9 volts and when there are no DTCs present that are inhibiting PSCM operation.

DTC U0159:00 (Lost Communication With Parking Assist Control Module A: No Sub Type Information) - This DTC will set if communication between the PSCM and the PAM fails. The PAM sends various commands to the PSCM along the HS-CAN bus. If these commands are missing for more than 80 milliseconds, then the PSCM will set U0159:00.
