The automobile fault code P1780 indicates a problem with the Transmission Control Switch (TCS). The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light. This fault code is triggered when the TCS is not cycled during the self-test, or when there is a faulty TCS, an open or shorted TCS harness, or a poor electrical connection in the TCS circuit.
To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour.
It is important to address this fault code promptly to ensure proper functioning of the transmission system.

P1780: Understanding The Transmission Control Switch Circuit Malfunction
The P1780 fault code refers to the Transmission Control Switch (TCS) being out of self-test range. The TCS is a switch located on the end of the transmission control selector lever.
It is used to engage or disengage the overdrive function of the transmission.
During the self-test, the TCS must be cycled. If the Powertrain Control Module (PCM) detects that the TCS is out of range during the self-test, the P1780 code will be set.
This code indicates a problem with the TCS and may require further diagnosis and repair.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1780 might be the culprit. This code can be caused by a few things, including the transmission control switch (TCS) not being cycled during the self-test, a faulty TCS, an open or shorted TCS harness, or a poor electrical connection in the TCS circuit. To visually inspect these possible causes, take a look at the related wiring harness and connectors. Check for any damaged components and keep an eye out for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Transmission Control Switch (TCS). This can happen if the TCS is not cycled during the self-test, if the switch itself is faulty, or if there is an issue with the TCS harness or circuit connection. To determine if the TCS is the culprit, visually inspect the wiring harness and connectors for any damage. Check for broken, bent, pushed out, or corroded pins on the connectors. This will help you identify and fix the problem.
To check for any open or shorted circuits in the Transmission Control Switch (TCS) harness and fix them, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded connector pins. This can help identify any issues with the TCS circuit. Additionally, make sure to cycle the TCS during the self-test to ensure it is functioning properly. By following these steps, you can diagnose and fix any open or shorted circuits in the TCS harness.
Wrap Up
If your engine light is on and you’re seeing the P1780 fault code, it could be due to a few reasons. First, check if the Transmission Control Switch (TCS) was cycled during the self-test.
If not, that could be the cause. Other possible causes include a faulty TCS, an open or shorted TCS harness, or a poor electrical connection in the TCS circuit. To fix the issue, visually inspect the wiring harness and connectors, looking for any damage or corrosion.
Also, check for broken, bent, or pushed out connector pins.
