Scan Tool Data Definitions (Disengage History)

SCAN TOOL DATA DEFINITIONS (DISENGAGE HISTORY)

The Cruise Control Scan Tool Definitions Disengage History is a common list for all of the available cruise control disengagement definitions available on the scan tool. The cruise control system equipped on the vehicle determines which cruise control disengagement parameters are available for review on the scan tool.

One of the following conditions must be present in order for a disengagement parameter to appear:
- The cruise control system is active and disengagement is requested.
- The engagement of the cruise control system is requested while a fault is present.

1st Gr Dis.: The PCM/ECM detects that the transmission is in Drive 1.

ALDL: The PCM/ECM detects that a fault in the ALDL wiring exists

Analog Outreach: The PCM/ECM detects a malfunction in the analog cruise control switch or in the cruise control switch wiring.

Bad Mem.: An internal PCM/ECM fault is detected.

Brk: The PCM/ECM detects that the stop lamp switch or the TCC brake switch/cruise release signal has been requested.

Brk < Cruise: The PCM/ECM detects that a stop lamp pedal activation had not occurred before the cruise control system was requested.

Cancel: The PCM/ECM detects that the cruise control cancel switch has been activated.

Clutch: The PCM/ECM detects that the clutch pedal has been pressed.

Cst Inhibit: The PCM/ECM detects that the Set/Coast switch is activated until the vehicle speed is below 40 km/h (25 mph).

Cst Disengage: The PCM/ECM detects that the cruise Set/Coast signal is ON when the cruise control system is OFF.

Driven Whl Spd Greater: The PCM/ECM detects that the traction control system is active.

Engine Run Time: The PCM/ECM detects that the engine run time counter is not active.

Eng Spd: The PCM/ECM detects that the engine speed is less than or greater than a predetermined RPM.

ETC: The PCM/ECM has detected that a TAC module fault is present.

High Accel: The vehicle acceleration is greater than the expected acceleration rate calculated by the PCM/ECM.

High Decel: The vehicle deceleration is greater than the expected deceleration rate calculated by the PCM/ECM.

High Ign. Volt: The PCM/ECM detects that the ignition voltage is above 18 volts.

Hi Spd: The PCM/ECM detects that the vehicle speed was greater than 265 km/h (165 mph).

Ill. Cruise Mde: The PCM/ECM will not allow cruise control operation with the current position of the cruise switches.

Inj. Dis.: The PCM/ECM detects a that the engine is overspeed and that the fuel injectors have been disabled.

Low Spd: The PCM/ECM detects that the vehicle speed had decreased to less than 40 km/h (25 mph) while the cruise control system was enabled.

Low Ign Volt.: The PCM/ECM detects that the ignition voltage is below 9 volts.

Malf: The PCM/ECM detects a malfunction in the PCM/ECM and that a DTC has been set.

Man Neutral Cruise: The PCM/ECM detects that transmission is in Neutral, Reverse or Park.

Metal Ovrtmp Active: The PCM/ECM detects that the engine has been overheated.

MPH Limited Fuel: The PCM/ECM detects a that the vehicle is overspeed and the fuel cut-off is active.

None: This parameter is displayed when a battery disconnect occurs.

Off: The PCM/ECM detects that the cruise On/Off switch was activated to turn the cruise control system Off.

Over Spd: This parameter is displayed when the current vehicle speed is greater than the set vehicle speed by more than a predetermined value.

Over Spd Tap-Down: This parameter is displayed when the Set/Coast switch is applied until the current vehicle speed is less than the set vehicle speed by more than a predetermined value.

PCM Inhibit: The PCM/ECM detects a RAM corruption.

Pedal > Cruise: The PCM/ECM detects that the accelerator pedal overrides the set vehicle speed for greater than 60 seconds.

RA/SC Sw. Press Together: The PCM/ECM detects that the Set/Coast switch and the Resume/Accel switch are active at the same time.

Sequence: The PCM/ECM detects that the specific sequence for enabling cruise control operation has not been completed.

Serial Data Fault: A fault in the serial data circuit from the cruise control switch to the BCM is detected.

TCS: The PCM/ECM detects that the traction control system had been activated.

Under Schedule: The PCM/ECM detects that the vehicle speed is less than the cruise memory speed by more than a predetermined amount.

Undriven Whl Spd Greater: The EBCM detects that the wheel speed of a non-drive wheel was greater than the wheel speed of a driven wheel.

Veh. Stability Active: The PCM/ECM detects that the vehicle stability system had been activated.
