Diagnostic Aids

WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

The wastegate circuits are provided with a voltage stabilizer diode package that may cause a DTC to set if one or both of its internal diodes have failed resulting in a short circuit between the ignition voltage circuit and the control circuit of the wastegate.
