Circuit/System Verification

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

Verify that all of the following scan tool parameters: = OK
- Pressure Control Solenoid Valve 1 Control Circuit High Voltage (L-363) tool displays Pressure Control Solenoid Valve 1 High Voltage Test Status
- Pressure Control Solenoid Valve 1 Control Circuit Low Voltage Test Status
- Pressure Control Solenoid Valve 1 Control Circuit Open Test Status
- Pressure Control Solenoid Valve 2 Control Circuit High Voltage Test Status
- Pressure Control Solenoid Valve 2 Control Circuit Low Voltage Test Status
- Pressure Control Solenoid Valve 2 Control Circuit Open Test Status (L-367) tool displays Pressure Control Solenoid Valve 2 Open Circuit Test Status
- Pressure Control Solenoid Valve 3 Control Circuit High Voltage Test Status
- Pressure Control Solenoid Valve 3 Control Circuit Low Voltage Test Status
- Pressure Control Solenoid Valve 3 Control Circuit Open Test Status (L372) tool displays Pressure Control Solenoid Valve 3 Open Circuit Test Status
- Pressure Control Solenoid Valve 4 Control Circuit High Voltage Test Status
- Pressure Control Solenoid Valve 4 Control Circuit Low Voltage Test Status
- Pressure Control Solenoid Valve 4 Control Circuit Open Test Status
- If any of the parameters do NOT display OK
  Refer to Circuit/System Testing
- If all of the parameters display OK
Verify that the following scan tool parameters track each other as engine RPM changes. (P2763 or P2764 only)
- Actual TCC Pressure Control Solenoid Valve Current
- TCC Pressure Control Solenoid Valve Current Command
- If the parameters do not track each other as engine speed RPM changes
  Refer to: Circuit/System Testing
- If the parameters do track each other as engine speed RPM changes
Verify DTC P0961-P0963, P0965-P0967, P0970, P0971, P2720, P2721, P2763, P2764 is only set as a history DTC.
- If any of the DTCs are set as current
  Refer to Circuit/System Testing
- If any of the DTCs are only set as history
  Refer to Testing for Intermittent Conditions and Poor Connections
Clear DTC P0961-P0963, P0965-P0967, P0970, P0971, P2720, P2721, P2763, P2764 from history.
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Verify DTC P0961-P0963, P0965-P0967, P0970, P0971, P2720, P2721, P2763, P2764 is not set.
- If any of the DTCs are set
  Refer to Circuit/System Testing
- If none of the DTCs are set
All OK.
