Scan Tool Data Definitions Cruise Control

Cruise Inhibit Signal Command: Displays Yes or No. Indicates if the PCM is commanding the cruise control module to inhibit cruise control operation.

Cruise Active: Displays Yes or No. The status of the cruise engaged signal. The cruise control module grounds the circuit when cruise control is on.

Scan Tool Data Definitions Disengage History

Important:  The following data list terms MAY NOT apply to all vehicle lines.

ABS:  Antilock Brake (ABS) is active.

Active Brake Yaw: A Class 2 message is received by the PCM that the Brake Yaw is active.

ALDL: A scan tool message to inhibit cruise control operation is received by the PCM.

Brake: A class 2 message is received by the PCM that a basic brake problem has occurred. The PCM senses any brake active operation.

Battery Voltage: The battery positive voltage is out of range.

Clutch Switch: A failure of the clutch switch has been detected.

CC Cancel Switch: A class 2 message is received by the PCM that a cruise cancel event has occurred.

CC Inhibit Circuit: A fault on the cruise control inhibit signal circuit has been detected.

Delta Vehicle Speed: The vehicle speed is greater or less than the cruise control operating criteria speed.

Engine Not Running: The engine is not running

Engine Run Time: The engine run time does not equal the cruise control enable criteria run time.

Engine Speed: The vehicle speed is greater or less than the cruise control enable criteria speed.

Injector: Any number of injectors are disabled by high mph.

Manual/Neutral CC: The vehicle is shifted into neutral while cruise control is in operation.

MPH Limited: The mph is limited, by the PCM controlling the fuel and electronic spark timing.

P0756: 2-3 shift solenoid valve performance.

P0758: 2-3 shift solenoid control circuit fault.

P0785: 3-2 shift solenoid control circuit fault.

Park Brake Active: A Class 2 message is received by the PCM that the parking brake is active.

Serial Communications: A class 2 serial communication problem is detected.

SMCC Fault: A fault is detected with the stepper motor cruise control module.

TCS: The traction control is active.

Trans: The clutch pedal is pressed on a manual transmission vehicle or when the gear selector is shifted out of DRIVE during cruise control operation.

Vehicle Speed Fault: A problem is detected with vehicle speed.

Vehicle Speed: The vehicle speed drops below the cruise control engaged criteria.
