DTC Chart: TCCM
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
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. CMDTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
| DTC | Description | Action |
|---|---|---|
| C1979:00 | IWE Solenoid Circuit Failure: No Sub Type Information | This DTC sets when the TCCM detects there is a possible mechanical fault present with the IWE system based on wheel speed message data. When the DTC is present IWE solenoid output shall continue to operate normally. PERFORM the Four-Wheel Drive (4WD) System Functional Test GO to Pinpoint Test A |
| C1979:11 | IWE Solenoid Circuit Failure: Circuit Short To Ground | GO to Pinpoint Test D |
| C1979:12 | IWE Solenoid Circuit Failure: Circuit Short To Battery | GO to Pinpoint Test D |
| C1979:13 | IWE Solenoid Circuit Failure: Circuit Open | GO to Pinpoint Test D |
| P0562:00 | System Voltage Low: No Sub Type Information | GO to Pinpoint Test C |
| P0563:00 | System Voltage High: No Sub Type Information | GO to Pinpoint Test C |
| P06B8:00 | Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error: No Sub Type Information | CLEAR the DTC. REPEAT the self-test. If the DTC still sets, INSTALL a new TCCM. REFER to: Transfer Case Control Module (TCCM) . |
| P1825:00 | 4-Wheel Drive Clutch Relay Open Circuit: No Sub Type Information | GO to Pinpoint Test F |
| P1826:00 | 4-Wheel Drive Low Clutch Relay Circuit To Battery: No Sub Type Information | GO to Pinpoint Test F |
| P1827:00 | 4-Wheel Drive Low Clutch Relay Circuit To Ground: No Sub Type Information | GO to Pinpoint Test F |
| U0100:00 | Lost Communication With ECM/PCM "A": No Sub Type Information | GO to Pinpoint Test G |
| U0101:00 | Lost Communication With TCM "A": No Sub Type Information | GO to Pinpoint Test H |
| U0121:00 | Lost Communication With Anti-Lock Brake System (ABS) Control Module: No Sub Type Information | GO to Pinpoint Test K |
| U0138:00 | Lost Communication with All Terrain Control Module | GO to Pinpoint Test I |
| U0140:00 | Lost Communication With Body Control Module (BCM): No Sub Type Information | GO to Pinpoint Test J |
| U0418:00 | Invalid Data Received From Brake System Control Module: No Sub Type Information | REFER to:Anti-Lock Brake System (ABS) and Stability Control . If no DTCs are present in the ABS module, REPEAT TCCM KOEO self-test. If U2300:54 returns, INSTALL a new TCCM. |
| U0439:00 | Invalid Data Received From All Terrain Control Module: No Sub Type Information | CLEAR the DTC. PERFORM ATCM KOEO self-test. Resolve all ATCM DTCs. REPEAT the TCCM KOEO self-test. If the DTC still sets, INSTALL a new ATCM. REFER to: Mode Select Switch (MSS) . |
| U2300:54 | Central Configuration: Missing Calibration | This DTC sets 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: Body Control Module B (BCMB) . If no DTCs are present, CARRY OUT a self-test. If U2300:54 returns, INSTALL a new TCCM. |
| U2300:55 | Central Configuration: Not Configured | This DTC sets upon power up only until all expected configuration data parameters (gearbox type, axle ratio, tire circumference) are received from the BCM. CARRY OUT a self-test of the BCM. If DTCs are present, REFER to: Body Control Module B (BCMB) . If no DTCs are present, CLEAR the DTCs. CARRY OUT self-test. If U2300:55 returns, INSTALL a new ATCM REFER to: Mode Select Switch (MSS) . |
| U2300:56 | Central Configuration: Invalid / Incompatible Configuration | This DTC sets if a 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: Body Control Module B (BCMB) . If no DTCs are present, CARRY OUT a self-test. If U2300:56 returns, INSTALL a new REFER to: Mode Select Switch (MSS) . |
| U2300:64 | Central Configuration: Signal Plausibility Failure | This DTC sets 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: Body Control Module B (BCMB) . If no DTCs are present, CARRY OUT a self-test. If U2300:64 returns, INSTALL a new REFER to: Mode Select Switch (MSS) . |
| U3000:04 | Control Module: System Internal Failure | CLEAR the DTC. REPEAT the self-test. If DTC U3000:04 is retrieved again, 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 again, 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 again, 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 B |
