Code C0323 Chevrolet Description

The transfer case shift control module controls the Transfer Case Lock Solenoid.
The lock is energized (locking action released, grounding the Lock Control Circuit) during gear shifts and in AUTO 4WD mode of operation. When power or ground is removed from the lock solenoid, (locking action applied), the transfer case motor is prevented from moving. In this manner, the system is capable of providing a 4H and 4L lock-up without the need of additional vehicle power to hold the transfer case in these positions.
This DTC detects an open lock control circuit or an open Lock feed.
