NOTE:
DTC U1900 will set in a module that is reporting a communication fault from another module on the data bus. The module that reports the fault is not the problem module. Do not install a new RCM
as part of the repair for a RCM
DTC U1900 fault. VIEW and REPAIR the following PIDs to determine the module with the concern: IC_MSG_RCM, PCM_MSG_RCM, OCS_MSG_RCM or APIM_MSG_RCM. For IC_MSG_RCM, PCM_MSG_RCM or OCS_MSG_RCM, REFER to MODULE COMMUNICATIONS NETWORK
to diagnose the High Speed Controller Area Network (HS-CAN)/module concern.For APIM_MSG_RCM, CHECK Accessory Protocol Interface Module (APIM) for DTCs. REFER to the appropriate part to diagnose the DTC concern. If no other DTCs are present, REFER to APIM Software Level Check in the General Procedures portion of INFORMATION AND ENTERTAINMENT SYSTEMS
