I could not see the diagrams, but are they the ones for the coolant temperature senor wiring going to ECU?

Hello again,

Yes they are of the Engine Coolant Temperature (ECT). If you left click on the diagram to bring it up, then right click on it, the first thing in the menu box is to open image in a new tab. Left click on this and it will open the diagram in a new tab and should be full page sized and a lot easier to read. Please get back to us with how everything turns out.

Thanks,

Vehicle phone requires service message on my radio screen and it gives a code but says short circuit to ground.

Hello again,

Okay, what is the code that it is giving you. A short to ground in any circuit will cause the fuse that protects that circuit to blow, so you can check the circuit that the code is talking about, or you can check all of your vehicle's fuses to find the one that is blown. Please get back to us with the code and we can go from there.

Thanks,

The code for the radio is b156011 active cellular antenna 1 circuit short to ground.

Hello again,

In the diagrams down below I have included the basics for the factory diagnostic troubleshooting guide for Direct Trouble Code (DTC) P0128 as well as the guide for DTC B156011. Basically for DTC P0128 I would replace the Engine Coolant Temperature (ECT) sensor and you just need to trace the wire coming from your vehicle's stereo and find the short to ground. I have also included a guide for how to find a short to ground in an automotive electrical circuit for you as well. Please go through these guides and get back to us with what you are able to find out.
