WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition ON, observe the DTC Information with a scan tool. DTCs P0033, P0034, or P0035 should not set.
- If any of the DTCs are set, refer to DTC P0033-P0035 for further diagnosis.
- Ignition ON, command the Turbocharger Bypass Solenoid Valve between Inactive and Active with a scan tool. An audible click should be heard.
- Engine running, command the Turbocharger Bypass Solenoid Valve between Inactive and Active with a scan tool while observing the following control circuit status parameters:
- Turbocharger Bypass Solenoid Valve Control Circuit High Voltage Test Status
- Turbocharger Bypass Solenoid Valve Control Circuit Open Test Status
- Turbocharger Bypass Solenoid Valve Control Circuit Low Voltage Test Status
The parameters should alternate between OK and Not Run with each change in command.
- Engine idling, rapidly depress the accelerator pedal from the rest position to the wide open throttle (WOT) position and release pedal. A valve that is stuck shut will generate an unusual pulsating noise. Compare to similar vehicle. There should not be any unusual noise.
- If there is unusual noise, refer to Turbocharger Cleaning and Inspection .
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
