Step 1: Check the Wiring
The first thing you should do when you encounter this issue is to check the wiring. Look for any loose or damaged wires that may be causing the short circuit.

Step 3: Check the Transmission Control Module
If the wiring and connectors are not the issue, you should check the Transmission Control Module (TCM).

If the TCM is the issue, you will need to replace it.

Finally, you should check the battery. A weak or dead battery can cause all sorts of issues with your vehicle, including the P1811 error code. You can check the battery using a multimeter to see if it is holding a charge. If the battery is weak or dead, you will need to replace it.
