Output State Control Mode

Output state control allows the technician to take control of certain parameters to function the transmission.

For example, output state control allows the technician to shift the transmission only when commanding a gear change. If the technician commands 1st gear in output state control, the transmission will remain in 1st gear until the technician commands the next gear.

Another example of the output state control features is that a technician can command the torque converter to turn ON or OFF to check operation.

This transmission output state control has one mode of operation; DRIVE. This mode has a unique set of operating requirements that the technician must meet before allowed to operate the torque converter or select gears.

NOTE: To operate output state control, the Transmission Range (TR) sensor and the Output Shaft Speed (OSS) sensor must be operational. No DTCs related to the TR sensor or the OSS sensor can be present.

- The vehicle requirements MUST BE MET when SENDING the output state control value. Refer to the vehicle requirements for each test.
- If the vehicle requirements are NOT MET when SENDING the output state control value, an ERROR MESSAGE will appear. Output state control is aborted and must be restarted.
- If, after the sent value is substituted, the vehicle requirements are no longer met, the PCM will cancel the output state control value and resume normal operations. No error message will be sent.
