3. Verify with a scan tool that DTCs P0601, P0603, P0604, or P062F are not set.

瀚慖f DTCs P0601, P0603, P0604, or P062F are set, replace the control solenoid valve and transmission control module assembly.

4. 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 Description

This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM) and the throttle actuator control

(TAC) system. This diagnostic also addresses if the ECM is not programmed.

The ECM monitors its ability to read and write to the memory. It also monitors a timing function. The ECM and the TAC processors are used to
