DTC P0658 or P0659
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an
overview of the diagnostic approach.

DTC Descriptors
DTC P0658
- Solenoid High Control Circuit Group 1 Low Voltage
DTC P0659
- Solenoid High Control Circuit Group 1 High Voltage
Diagnostic Fault Information
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 parts.
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
* The engine speed is greater than 500 RPM for 5 seconds.
* Ignition voltage is 8.6 volts or greater.
* High side driver 1 is enabled.
* DTC P0658 has not set this ignition.
P0659
* DTC P0659 has not set this ignition.
* Ignition voltage is 8.6 volts or greater.
* Ignition switch transitions from OFF to run position.
Conditions for Setting the DTC
P0658
The TCM detects an internal open or short to ground on the high side driver 1 for 1 second.
P0659
The TCM detects an internal short to voltage on the high side driver 1 circuit for 1 second after engine start.
Action Taken When the DTC Sets
P0658
* DTC P0658 is a Type A DTC.
* The TCM turns OFF high side driver.
* The TCM turns OFF all solenoids.
* The TCM commands maximum line pressure.
* The TCM freezes transmission adaptive functions.
* The TCM commands the TCC OFF.
* The TCM allows the vehicle to operate in transmission protection mode.
* The TCM inhibits the TAP Up/Down function.
* The TCM inhibits manual shifting of forward gears.
