B1342	ECU is Defective	Instrument Cluster	Clear all DTCs. Retrieve the DTCs. If DTC B1342 is still present, install a new instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
B1363	Ignition Start Circuit Failure	Instrument Cluster	See PINPOINT TEST 23: DTC B1363 - IGNITION START CIRCUIT FAULT , .
B2143	NVM Memory Failure	Instrument Cluster	See PINPOINT TEST 5: THE ODOMETER IS INOPERATIVE , .
B2207	ECU ROM Checksum	Instrument Cluster	Clear all DTCs. Retrieve the DTCs. If the DTC B2207 is still present, install a new instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
B2477	Module Configuration Failure	Instrument Cluster	Reconfigure the instrument cluster. See MODULE CONTROLLED FUNCTIONS , .
B2675	Trip Reset Button Stuck	Instrument Cluster	Verify that there is no interference between the instrument cluster lens or mask and the trip reset button. If OK, install a new instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
C1221	ABS Warning Lamp Output Circuit Short to Ground	Instrument Cluster	See PINPOINT TEST 16: BRAKE WARNING INDICATOR IS NEVER ON , .
C1226	Brake Warning Lamp Output Circuit Short to Ground	Instrument Cluster	See PINPOINT TEST 8: ANTI-LOCK BRAKE SYSTEM (ABS) WARNING INDICATOR IS NEVER/ALWAYS ON , .
C2784	RAM Checksum Failure	Instrument Cluster	Clear all DTCs. Retrieve the DTCs. If DTC C2784 is still present, install a new instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
U0102	Lost Communication With the Transfer Case Control Module	Instrument Cluster	See PINPOINT TEST 19: 4WD AND 4WD LOW INDICATOR IS NEVER/ALWAYS ON , .
U0140	Lost Communication With the Body Control Module (GEM)	Instrument Cluster	Monitor the instrument cluster indicators and warning indicators for correct operation. If any indicators or warning indicators do not function correctly, See SYMPTOM TROUBLESHOOTING CHART - INSTRUMENT CLUSTER , . If all indicators are functioning correctly, clear the DTCs. Repeat the self test, If DTC U0140 returns, install a new SJB. See SMART JUNCTION BOX (SJB) , .

If any gauges indicators or warning indicators do not function correctly, See SYMPTOM TROUBLESHOOTING CHART - INSTRUMENT CLUSTER , . If all indicators are functioning correctly, clear the DTCs. Repeat the self test, If DTC U0294 returns, install a new PCM. See POWERTRAIN CONTROL MODULE (PCM) REMOVAL / INSTALLATION , .
U2023	Fault Received From External Node	Instrument Cluster	See PINPOINT TEST 11: MALFUNCTION INDICATOR LAMP (MIL) INDICATOR IS NEVER ON , .
U2050	No Application Present	Instrument Cluster	Reflash the instrument cluster. If the DTC occurs after a software reflash, reflash the instrument cluster again. If the DTC is present after each attempt to reflash, install a new instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
U2472	Unexpected Ignition State	Instrument Cluster	Clear all DTCs. Repeat the instrument cluster self-test. If DTC U2472 is still present, install a new smart junction box (SJB). See SMART JUNCTION BOX (SJB) , . Test the system for normal operation.
