P1DB1 Chrysler Code - Transmission Control Module System Voltage Excessively Low
Quick Answer
The Transmission Control Module (TCM) monitors the system voltage level at the TCM supply voltage terminal for the following failure conditions: - System Voltage Excessively Low - System Voltage Low - System Voltage High If the TCM supply voltage is below a threshold that is lower than the System Voltage Excessively Low threshold, the TCM will not supply power to the solenoid valves and pressure regulators. Common causes include Open fuse, Low battery voltage, Engine charging system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1DB1 Chrysler Description
- System Voltage Excessively Low
- System Voltage Low
- System Voltage High
If the TCM supply voltage is below a threshold that is lower than the System Voltage Excessively Low threshold, the TCM will not supply power to the solenoid valves and pressure regulators. A Diagnostic Trouble Code (DTC) is set when one of the diagnostic voltage thresholds is reached for a calibrated amount of time.
What are the Possible Causes of the DTC P1DB1 Chrysler?
- Open fuse
- Low battery voltage
- Engine charging system
- Faulty Transmission Control Module (TCM)
