P1DB1 - Transmission Control Module System Voltage Excessively Low
P1db1 DescriptionThe 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. A Diagnostic Trouble Code (DTC) is set when one of the diagnostic voltage thresholds is reached for a calibrated amount of time.
