| U0300 | Internal Control Module Software Incompatibility |
NOTE:
When installing a new RCM
, always make sure the correct RCM
is being installed. If an incorrect RCM
is installed, DTCs will result. CARRY OUT Programmable Module Installation (PMI). REFER to
MODULE CONFIGURATION
. |
| U1900 | CAN Communication Bus Fault - Receive Error |
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 repair for a RCM
DTC U1900 fault. VIEW and RECORD IC_MSG_ RCM
, PCM_MSG_ RCM
and OCS
_MSG_ RCM
fault PIDs to determine the module with the concern. REFER to
MODULE COMMUNICATIONS NETWORK
to diagnose the High Speed Controller Area Network (HS-CAN)/module concern. |
