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

CLEAR the DTCs and CARRY OUT a self-test of the PSCM. If the DTCs return, CARRY OUT a self-test of the PAM. If the scan tool indicates that the PAM is not responding, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the network communication concern. If DTCs are still present in the PAM, REFER to PARKING AID SYSTEM - ACTIVE PARK ASSIST for diagnostic information.
