What Does The FIAT P1DB2 Code Mean?

The voltage supply circuit(s) for the solenoids and pressure regulators are monitored for open circuits, shorts to ground, and shorts to voltage.

If a failure is detected, the Transmission Control Module (TCM) will deactivate the affected power supply circuit and set a corresponding Diagnostic Trouble Code (DTC) relevant to the fault that was detected.
