Traction Control is disabled and I have Service Stability warning with DTC of C0283. The brake system is JL4.
I originally had C0131 and I replaced the pressure valve and the EBCM. Due to rust, I was unable to separate the EBCM from the pressure valve and replaced both with a used part. After reconnecting everything, the vehicle gives the code C0283 (Mode Switch Circuit Malfunction).
I found these two troubleshooting references on the web which I had trouble following:
Here is what I have done on this code:
* Cleaned ground by the EBCM
* Checked electrical connection to the EBCM
* Removed the TCS switch and tested the 4 wires - three are connected to either power or ground, one was open. It was one of the brown wires and coded as H on the connector.
Does anyone have any suggestions on what I should do to isolate the source of the DTC?
Thanks
Jonathan
