Circuit/System Verification
1. Ignition ON, verify with a scan tool the transmission ISS/OSS Supply Voltage test status parameter displays OK.
2. Engine idling in Park, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter
should change with the engine speed and not drop out.
3. 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.
Circuit/System Testing
Note: You must perform the Circuit/System Verification first.
1. Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement (See: Transmission and
Drivetrain/Automatic Transmission/Transaxle/Valve Body/Service and Repair/6T70/6T75 - Automatic Transmission/Control Valve Body
Cover Replacement).
2. Connect the TCM harness connector.
3. Disconnect the ISS wiring harness connector X3 from the control solenoid valve assembly.
