* The TCM enables torque management.

* The TCM freezes transmission adaptive functions.

* The TCM turns OFF all solenoids.

* The TCM turns OFF the TCC solenoid.

P0723

* DTC P0723 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 enables torque management.

Conditions for Clearing the DIC/DTC

DTCs P0722 and P0723 are Type A DTCs.

Diagnostic Aids

Inspect the ISS/OSS, harness, connector and control solenoid valve assembly for metallic debris and output shaft housing machined slots for

damage or misalignment. Proper torque of the ISS/OSS mounting bolt is critical to proper speed sensor operation.

For equivalent regional tools, refer to Special Tools (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Tools and Equipment).

Circuit/System Verification

1. Ignition ON, verify with a scan tool the transmission ISS/OSS supply voltage test status parameter displays OK.

2. Operate the vehicle at 16-32 km/h (10-20 mph) while observing the Transmission OSS parameter on the scan tool. The Transmission OSS

parameter should vary with the vehicle 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 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly

Replacement (See: Powertrain Management/Transmission Control Systems/Actuators and Solenoids - Transmission and

Drivetrain/Actuators and Solenoids - A/T/Shift Solenoid/Service and Repair).
