P0717
* DTC P0717 is a Type A DTC.
* The high side driver is turned OFF.
* The TCM turns OFF all solenoids.
* The TCM freezes transmission adaptive functions.
* The TCM inhibits Tap Up/Down functions.
* The TCM inhibits manual shifting of forward gears.
Conditions for Clearing the DTC
P0716 and P0717 are Type A DTCs.
Diagnostic Aids
Inspect the ISS/OSS, harness, connector, and control solenoid valve assembly for metallic debris and the 1-2-3-4 and 3-5-R clutch housing splines
on the outside diameter surface for damage or misalignment. Proper torque of the ISS/OSS mounting bolt is critical to proper speed signal
operation.

For equivalent regional tools, refer to Special Tools (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Tools and
Equipment/6L45/6L50/6L80/6L90 - Automatic Transmission).
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 Transmission ISS parameter on the scan tool while varying the engine speed. The Transmission ISS
parameter should vary 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 Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly
