Diagnostic Fault Information
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The diagnostic Fault Information table identifies each circuit that makes up an electrical subsystem and the associated circuit faults. DTCs and symptoms are listed in the table for all circuit fault modes. This information can be used to diagnose an electrical fault, or as a quick visual aid showing how the different symptoms and DTCs apply for the subsystem being diagnosed.
Even though all the DTCs and symptoms are shown in this table it does not mean they will all be diagnosed in the same procedure.
An example table from an engine coolant temperature (ECT) procedure:
| Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
| ECT Sensor Signal | P0117 | P0118 | P0118 | P0125, P0128 |
| ECT Low Reference | - | P0118 | P0118 | P0125, P0128 |
