| DTC | Description | Action |
|---|---|---|
| P0562:00 | System Voltage Low: No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| P0563:00 | System Voltage High: No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| P185A:00 | Differential Lock-Up Input Switch Circuit High: No Sub Type Information |
NOTE:
Failure to place the ELD MSS in OFF position prior to carrying out a self-test of the TCCM results in the false setting of DTC P185A:00. GO to Pinpoint Test A |
| P185D:00 | Differential Lock-Up Control Circuit Low: No Sub Type Information | GO to Pinpoint Test D |
| P187C:00 | Differential Lock-Up Control Circuit/Open: No Sub Type Information | GO to Pinpoint Test B |
| P187D:00 | Differential Lock-Up Control Circuit Low: No Sub Type Information | GO to Pinpoint Test B |
| P187E:00 | Differential Lock-Up Control Circuit High: No Sub Type Information | GO to Pinpoint Test C |
| U0100:00 | Lost Communication With ECM / PCM "A": No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| U0101:00 | Lost Communication With TCM "A": No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| U0121:00 | Lost Communication With ABS Control Module: No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| U0140:00 | Lost Communication With BCM: No Sub Type Information | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| U0418:00 | Invalid Data Received From Brake System Control Module: No Sub Type Information | REFER to: Anti-Lock Brake System (ABS) and Stability Control . |
| 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 (BCM) . If no DTCs are present, 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 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 (BCM) . 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 sets 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: Body Control Module (BCM) . If no DTCs are present, 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 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 (BCM) . If no DTCs are present, 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 U3000:49 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 U3000:49 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 | REFER to: Four-Wheel Drive Systems - Electronic Shift . |
| All other TCCM DTCs | REFER to: Four-Wheel Drive Systems - Electronic Shift . | |
