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.
