Scan Tool Output Control | Additional Menu Selection(s) | Description
--- | --- | ---
TCC Pressure Control Solenoid | -- |

• | The transmission control module (TCM) commands the torque converter clutch pressure control (TCC PC) solenoid pressure in order to apply and release the TCC.

• | When the ignition is ON, and the engine is OFF, there are no limits to this control. The solenoid remains ON until commanded OFF and vice versa.

• | When the engine is running, the following control limits apply:

- | If the transmission range is Park, and the transmission is in hot mode, the TCC PC solenoid may not be commanded OFF. If the solenoid is requested OFF, the message "TCC OFF command disabled in Hot Mode" appears on the scan tool display.

- | The TCC PC solenoid may not be commanded OFF for more than a calibrated amount of time. If the solenoid is commanded OFF, for a certain amount of time, the message "TCC OFF time has been exceeded" appears on the scan tool display.

Shift Solenoid 1 Shift Solenoid 2 | -- |

• | The TCM commands Shift Solenoid 1 and Shift Solenoid 2 ON and OFF.

• | When the ignition is ON, and the engine is OFF, there are no limits to this control. The solenoid remains ON until commanded OFF, and vice versa. When the output control is exited, the solenoid state is determined by the TCM.

• | When the engine is running, the following control limits apply:

- | The transmission range must be in Park or Neutral. If the transmission range is not in Park or Neutral, the message "Engine running and transmission range is not Park/Neutral" appears on the scan tool display

- | The solenoid remains ON until commanded OFF, and vice versa. When the output control is exited, the solenoid state is determined by the TCM.

- | Transmission range DTCs must not be active. If a transmission range DTC is active, the message "Engine running with transmission DTC present" appears on the scan tool display.

Line PC Solenoid | -- |

• | The scan tool is used to request pressure in increments of 207 kPa (30 psi) from 0 to 1862 kPa (0 to 270 psi). The TCM will then command the solenoid to achieve the requested pressure.

• | When the ignition is ON, and the engine is OFF, the pressure request may be controlled within calibrated limits. There are no limits to the output control when the engine is OFF.

• | When the engine is running, the following control limits apply:

- | When the transmission range is in Park or Neutral, the pressure request may be controlled within calibrated limits. The engine speed must be less than 1,500 RPM. If the engine speed is greater than 1,500 RPM, the message "TR in park/neutral and engine speed over 1,500 RPM" appears on the scan tool display.

- | When the transmission range is not Park or Neutral, the requested pressure can only be controlled equal to or greater than the pressure determined by the TCM. The TCM does not allow a pressure to be selected that may cause damage to the transmission. If the requested pressure is less than allowed by the TCM, the message "Requested pressure for the Line PC Solenoid is too low" appears on the scan tool display.

- | Transmission range DTCs must not be active. If a transmission range DTC is active, the message "Engine running with transmission DTC present" appears on the scan tool display.

PC Solenoid 2 | -- |

• | The TCM commands the pressure control solenoids in order to apply and release the clutches.

• | When the ignition is ON, and the engine is OFF, there are no limits to this control. The solenoid remains ON until commanded OFF, and vice versa. When the output control is exited, the solenoid state is determined by the TCM.

• | When the engine is running, the following control limits apply:

- | The transmission range must be in Park or Neutral. If the transmission range is not in Park or Neutral, the message "Engine running and transmission range is not Park/Neutral" appears on the scan tool display.

- | The solenoid remains ON until commanded OFF, and vice versa. When the output control is exited, the solenoid state is determined by the TCM

- | Transmission range DTCs must not be active. If a transmission range DTC is active, the message "Engine running with transmission DTC present" appears on the scan tool display.

PC Solenoid 3 | --
PC Solenoid 4 | --
PC Solenoid 5 | --
High Side Driver 2 | -- |

• | The TCM commands the driver for the solenoid voltage supply ON and OFF.

• | When the ignition is ON, and the engine is OFF, there are no limits to this control.

• | High side drivers may not be commanded ON and OFF with the scan tool if the engine is running.
