Circuit/System Verification
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.
IMPORTANT:
On the scan tool, the powertrain relay is referred to as the EC ignition relay.
- If DTCs B1370, B1380, P0685, P0689, or P0690 are set, diagnose those DTCs first.
- Ignition ON, engine OFF, observe both the Ignition 1 voltage signal and the EC Ignition Relay Feedback Signal parameters on the scan tool. Both parameter values should display no more than 3 volts difference between the 2 parameters.
- If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records data list.
