To diagnose the P1DB1 Dodge code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
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. A Diagnostic Trouble Code (DTC) is set when one of the diagnostic voltage thresholds is reached for a calibrated amount of time.
