Cruise Control: Scan Tool Testing and Procedures
Scan Tool Data Definitions (Disengage History)
Scan Tool Data Definitions (Disengage History)
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.
Accel Rate
-
The engine control module (ECM) detects that the vehicle acceleration is greater than the calibrated cruise control threshold.
APP Override
-
The ECM detects that the accelerator pedal overrides the set vehicle speed for approximately 60 seconds.
Brake
-
The ECM detects that the stop lamps have been activated according to the brake pedal position (BPP) sensor / stop lamp switch input from the
platform module. Also, the brake pedal being applied according to the brake fluid pressure sensor input can also set this disengagement reason
with vehicles equipped with the vehicle stability enhancement system (VSES).
BPP Data
-
The ECM detects an invalid brake pedal apply serial data message from the platform module.
BPP DTC
-
The ECM detects that DTC P0703 is active.
Cancel
-
The ECM detects that the cruise control cancel switch has been activated.
Clutch
-
The ECM detects that the clutch pedal switch has been activated.
Coast Disengage
-
When the ECM detects that the cruise set/coast signal is active and the throttle blade fully closes the cruise control system will disengage until the
ECM detects that the set/coast signal is inactive. The cruise control system will then engage and set with the new vehicle speed.
Coast Speed Low
-
The ECM detects that the Set/Coast switch is activated until the vehicle speed is below 37 km/h (23 mph).
Cruise S/W
-
The ECM detects that a cruise control software execution error is present.
Cruise Sw Data
-
A fault in the serial data circuit from the cruise control switch to the platform module is detected.
Cruise Sw. Off
-
The ECM detects that the cruise On/Off switch was turned to OFF when the cruise control system was enabled.
D Whl Spd Low
-
The ECM detects the driven wheels are at a slower speed than the non-driven wheels.
D Whl Spd Hi
-
The ECM detects the driven wheels are at a faster speed than the non-driven wheels.
Decel Rate
-
The ECM detects that the vehicle deceleration is greater than the calibrated cruise control threshold.
DLC Override
-
The ECM detects that a DLC override has occurred.
DTC Set
-
The ECM detects that a DTC has been set which affects the cruise control operation.
