Scan Tool Data Definitions - Disengage History

Brake Switches: The TAC module detects one of the brake switches active (TCC Brake Switch/Cruise Control Brake Switch or Stop Lamp Switch).

Pedal Initialization: The PCM does not detect the brake or clutch switches active during an ignition cycle.

Clutch Switch: The TAC module detects the clutch switch active.

S/C (Set/Coast) On, CC (Cruise Control) Off: The TAC module detects the Cruise Set/Coast signal is ON. When the switch is pushed (Cruise Coast Mode), this parameter will be displayed. If a fault is present with the Cruise Set/Coast signal circuit, this parameter will be displayed.

Coast Speed Low: The Set/Coast switch is pushed and held until vehicle speed drops below 32 km/h (20 mph). Vehicle speed below 32 km/h (20 mph) will disable the cruise system.

TAC Inhibit: The TAC module has detected that an Electronic Throttle Control fault is active.

Accel (Acceleration) Rate: The vehicle acceleration is greater than the expected acceleration rate which is calculated by the PCM.

Decel (Deceleration) Rate: The vehicle deceleration is greater than the expected deceleration rate which is calculated by the PCM.

High Speed: The PCM detects that the vehicle speed is greater than 265 km/h (165 mph).

CC (Cruise Control) Switch Position: The TAC module will not allow cruise with the current position of the cruise switches.

Low Speed: The PCM detects that the vehicle speed is less than 39 km/h (24 mph) when cruise enable is attempted.

No History: The No History parameter is displayed when a battery disconnect occurs.

Cruise Off: The TAC module does not detect that the cruise enable switch is active.

Over Set Speed: The TAC module detects that the vehicle speed is greater than the cruise memory speed by more than a predetermined amount or, the vehicle speed is greater than a predetermined value during a transient maneuver, such as, Resume, Accel, Tap-up or Tap-downs, etc.

S/C On-Speed High: This parameter is displayed when the Set/Coast switch is applied (tap down vehicle speed) and the vehicle speed is greater than the cruise memory speed by more than a predetermined value. For example, if the cruise control system is set to maintain a vehicle speed of 48 km/h (30 mph) then the vehicle is accelerated to 80 km/h (50 mph) and you press the Set/Coast again, the S/C On-Speed High message appears in the Cruise Control Disengage History.

PCM Inhibit: The PCM detects one of the following conditions:
^ The transmission is not in gear.
^ The Engine Coolant Over Temperature-Fuel Disabled mode is active.
^ The TAC module detects a Resume/Accel switch fault.
^ The TAC module detects a Set/Coast switch fault.
^ The PCM detects a Vehicle Speed sensor fault. A brake or clutch switch fault is detected.
^ An internal PCM fault is detected.

Two CC Commands: The TAC module detects the Set/Coast and Resume/Accel switches are active at the same time.

PCM Error: An internal PCM fault is detected. Traction Loss: The TAC module detects the vehicle is in a Traction Control event.

Under Set Speed: The TAC module detects that the vehicle speed is less than the cruise memory speed by more than a predetermined amount or, the vehicle speed is less than a predetermined value during a transient maneuver, such as, Resume, Accel, Tap-up or Tap-downs, etc.
