Transfer Case Control Module (TCCM) DTC Chart - ELD System
NOTE:
This module utilizes a 5-character DTC followed by a 2-character failure type code. The failure type code provides information about specific fault conditions such as opens or shorts to ground. have an additional 2-character DTC status code suffix to assist in determining DTC history.
NOTE:
Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to BATTERY, MOUNTING AND CABLES

| U0418:00 | Invalid Data Received From Brake System Control Module: No Sub Type Information | REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL to diagnose the wheel speed sensor concern. |
| U2300:54 | Central Configuration: Missing Calibration | This DTC can set if one or more expected configuration data identifications is missing (gearbox type, tire circumference) from the BCM . CARRY OUT a self-test of the BCM . If DTCs are present, REFER to MULTIFUNCTION ELECTRONIC MODULES . If no DTCs are present, CLEAR the DTCs. CARRY OUT a self-test. If U2300:54 returns, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U2300:55 | Central Configuration: Not Configured | This DTC can set upon power up only until all expected configuration data parameters (gearbox type, axle ratio, tire circumference) is received from the BCM . CARRY OUT a self-test of the BCM . If DTCs are present, REFER to MULTIFUNCTION ELECTRONIC MODULES . If no DTCs are present, CLEAR the DTCs. CARRY OUT self-test. If U2300:55 returns, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U2300:56 | Central Configuration: Invalid/Incompatible Configuration | This DTC can set if one expected configuration data parameter is out of range (gearbox type, axle ratio, tire circumference) from the BCM . CARRY OUT a self-test of the BCM . If DTCs are present, REFER to MULTIFUNCTION ELECTRONIC MODULES . If no DTCs are present, CLEAR the DTCs. CARRY OUT a self-test. If U2300:56 returns, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U2300:64 | Central Configuration: Signal Plausibility Failure | This DTC can set if the expected axle ratio or tire circumference is out of range from the BCM . CARRY OUT a self-test of the BCM . If DTCs are present, REFER to MULTIFUNCTION ELECTRONIC MODULES . If no DTCs are present, CLEAR the DTCs. CARRY OUT a self-test. If U2300:64 returns, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U3000:41 | Control Module: General Checksum Failure | CLEAR the DTC. REPEAT the self-test. If DTC U3000:41 is retrieved, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U3000:46 | Control Module: Calibration/Parameter Memory Failure | CLEAR the DTC. REPEAT the self-test. If DTC U3000:46 is retrieved, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U3000:49 | Control Module: Internal Electronic Failure | CLEAR the DTC. REPEAT the self-test. If DTC U3000:49 is retrieved, INSTALL a new TCCM . REFER to TRANSFER CASE CONTROL MODULE (TCCM) . |
| U300D:11 | Ignition Input On/Start: Circuit Short To Ground | GO to PINPOINT TEST L . |
