Dodge Code P1776 is a transmission control module (TCM) code that is triggered when the TCM detects that the low/reverse switch is closed while the vehicle is performing partial or full powertrain energy management control cycle (PEMCC) or full energy management control cycle (FEMCC). This code is a common issue for Dodge vehicles and can be caused by a range of issues, from wiring and connector problems to transmission pan debris and valve body damage. In this article, we will discuss the causes and solutions for Dodge Code P1776.
Causes and Solutions for Dodge Code P1776
| Cause | Solution |
|---|---|
| Related Diagnostic Trouble Code P0841 may be present | Replace related parts |
| Intermittent wiring or connector problems | Check wiring and connectors |
| L/R pressure switch sense circuit is open, shorted to ground or to voltage | Repair or replace circuit |
| Extremely low battery (system) voltage | Recharge or replace battery |
| Transmission pan has debris caused by valve body damage | Replace or repair valve body |
| Transmission internal problems, SSV sticking, or valve body damage | Replace or repair valve body |
| PCM has failed | Replace PCM |
When Dodge Code P1776 is triggered, it is important to accurately identify the cause in order to provide an effective solution. The code can be caused by a range of issues from wiring and connector problems to transmission pan debris and valve body damage. In this article, we have provided an overview of the causes and solutions for Dodge Code P1776, including information on related service bulletins. With this information, mechanics, technicians and vehicle owners can more accurately identify and address the issues that could be causing this code.
If Dodge Code P1776 is present, it is likely that the related Diagnostic Trouble Code P0841 is also present. This code is triggered when the transmission control module (TCM) detects that the Low/Reverse switch is in an open or closed state when the vehicle is performing a Partial or Full Powertrain Energy Management Control Cycle (PEMCC) or Full Energy Management Control Cycle (FEMCC). To address this issue, it is necessary to replace the related parts such as the Low/Reverse switch and the transmission control module (TCM).
Intermittent Wiring or Connector Problems
Another potential cause of Dodge Code P1776 is intermittent wiring or connector problems. This can be caused by a faulty connector, a damaged wire, or a corroded connector. To ensure that this issue is addressed correctly, it is important to check all wiring and connectors for damage and corrosion. If any damage is found, it is necessary to repair or replace the damaged parts.
L/R Pressure Switch Sense Circuit
The L/R pressure switch sense circuit is another potential cause of Dodge Code P1776. This circuit is responsible for sensing the pressure in the transmission and communicating this information to the transmission control module (TCM). If this circuit is open, shorted to ground or to voltage, it is necessary to repair or replace the circuit to address the issue.
Extremely Low System Voltage
Another common cause of Dodge Code P1776 is extremely low system voltage. This can be caused by a faulty battery or a faulty alternator. To address this issue, it is necessary to recharge or replace the battery and/or the alternator.
Transmission Pan Debris and Valve Body Damage
The transmission pan can also be a potential cause of Dodge Code P1776. This can be caused by debris in the transmission pan or valve body damage. To address this issue, it is necessary to replace or repair the valve body.
Transmission Internal Problems, SSV Sticking or Valve Body Damage
Transmission internal problems, SSV sticking or valve body damage can also cause Dodge Code P1776. To address this issue, it is necessary to replace or repair the valve body.
PCM Has Failed
Finally, Dodge Code P1776 can be caused by a failed PCM. To address this issue, it is necessary to replace the PCM.
Conclusion
Dodge Code P1776 is a transmission control module (TCM) code that is triggered when the TCM detects that the low/reverse switch is closed while the vehicle is performing partial or full powertrain energy management control cycle (PEMCC) or full energy management control cycle (FEMCC). This code is a common issue for Dodge vehicles and can be caused by a range of issues, from wiring and connector problems to transmission pan debris and valve body damage. In this article, we discussed the causes and solutions for Dodge Code P1776. With this information, mechanics, technicians, and vehicle owners can more accurately identify and address the issues that could be causing this code.
