- Normal Operation and Fault Conditions
The TCCM monitors the internal circuitry and memory for errors. If a fault is detected multiple times, a DTC is set.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition TCCM P06B8:00 Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error: No Sub Type Information Sets when the TCCM detects an internal control module Non-Volatile Random Access Memory (NVRAM) Error. INSTALL a new TCCM. REFER to: Transfer Case Control Module (TCCM) . TCCM U3000:04 Control Module: System Internal Failure This DTC sets if an internal error is detected while the clutch is on. INSTALL a new TCCM. REFER to: Transfer Case Control Module (TCCM) . TCCM U3000:46 Control Module: Calibration/Parameter Memory Failure This DTC sets if the two-point motor or clutch calibration is invalid. INSTALL a new TCCM. REFER to: Transfer Case Control Module (TCCM) . TCCM U3000:49 Control Module: Internal Electronic Failure This DTC sets if voltage levels vary across different internal circuit. INSTALL a new TCCM.
