3. Connect each component associated with the affected 5 V reference circuit one at a time while monitoring the appropriate scan tool 5 V



Reference Circuit Voltage parameter. Verify the voltage remains between 4.8-5.2 V.



瀚慖f not within the specified range when a component is connected, test the signal circuit of that component for a short to voltage. If the



circuit tests normal, replace the component.

DTC Descriptors



DTC P0658



- Solenoid High Control Circuit Group 1 Low Voltage



DTC P0659



- Solenoid High Control Circuit Group 1 High Voltage



Circuit/System Description



The transmission control module (TCM) high side driver 1 is located inside of the control solenoid valve assembly, which has no serviceable



components. The high side driver 1 provides power to the TCM pressure control solenoids and shift solenoids. This fault is handled inside the TCM



and no external circuits are involved.



Conditions for Running the DTC



P0658



* High side driver 1 is enabled.
