Mercedes-Benz 722.9 Conductor Plate TCM Repair
This is a repair service for your existing 2004+ Mechatronic Mercedes Benz 722.9 Transmission Control Module (TCM) Conductor Plate or VGS that eliminates the need for any programming or SCN coding on vehicles that utilize the 7 speed transmission (7G Tronic). Our repair service is the only way to avoid the costly fees of programming a replacement conductor plate. Beware of other repair services that still require a Mercedes scan tool to clear the error codes that cause the vehicle to remain in limp mode. Circuit Board Medics offers the option to include a scan tool that will clear the codes when we return the rebuilt 722.9 conductor plate (see details below).

Just reinstall the Mercedes TCM on your valve body, and you’re back in business!
Please do not ship your TCM with the valve body or the solenoids.
When removing your TCM, take care not to damage the transmission connection plug. As pictured below, the plug sticks up through the body of the transmission and must be pulled out along a straight path to avoid damage. There is a $50 charge if the transmission connection plug is broken.
Symptoms of a failed mechatronics transmission control module conductor plate can cause the vehicle to enter into limp mode and will also cause the following error codes - our repair service will only correct the following error codes:
- Turbine Speed Sensor - Y3/8N1
- 0715 - Input/Turbine Speed Sensor Circuit Malfunction
- 0716 - Input/Turbine Speed Sensor Circuit Range/Performance
- 0717 - The signal from component Y3/8N1 (Turbine Speed Sensor (VGS)) is not available
- 0718 - The signal from component Y3/8N1 (Turbine Speed Sensor (VGS)) is defective
- P2204 - The signal from component Y3/8N1 (Turbine speed sensor (VGS)) is not available
- P2205 - The signal from component Y3/8N1 (Turbine Speed Sensor (VGS)) is defective
- Internal Speed Sensor - Y3/8N2
- 2766 - Excessive rpm’s have occurred at component Y3/8n2 (Internal speed sensor (VGS))
- 2767 - The signal from component Y3/8n2 (Internal speed sensor (VGS)) is not available
- 2768 - Component Y3/8n2 (Internal speed sensor (VGS)) is defective
- P2200 - Component Y3/8n2(Internal Speed Sensor (VGS)) is not available
- P2201 - The signal from component Y3/8n2 (Internal speed sensor (VGS)) is defective
- Output Speed Sensor - Y3/8N3
- 0720 - Output Speed Sensor Circuit Malfunction
- 0721 - Output Speed Sensor Range/Performance

- P2206 - The signal from component Y3/8N3 (Output Speed Sensor (VGS)) is not available
- P2207 - The value of component Y3/8n3 (Output Speed Sensor) is implausible
False diagnostic codes for the Output Speed Sensor can be caused by faulty wheel speed sensors. For better diagnosis, please scan your ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) modules for wheel speed sensor codes and inspect wheel sensor data PID (Parameter Identification Data). If any wheel speed sensor codes are present or a wheel speed "data is implausible" message exists, we recommend that you replace all affected wheel speed sensors and test again before removing your TCM.
If you are experiencing any other error codes than the ones listed above, please give us a call at (800) 547-2049 to discuss options.
