Envoy 4WD V8-5.3L VIN P (2004)
Engine Speed: The PCM/ECM detects that the engine speed is less than or greater than a calibrated RPM.
ETC: The PCM/ECM detects a fault within the TAC system.
First Gear: While the cruise control system is active, the PCM/ECM detects that the transmission is in Drive 1.
High Accel.: The PCM/ECM detects that the vehicle acceleration is greater than the calibrated cruise control threshold.
High Decel.: The PCM/ECM detects that the vehicle deceleration is greater than the calibrated cruise control threshold.
High Speed: The PCM/ECM detects that the vehicle speed is greater than the calibrated amount.
Illegal Mode: The PCM/ECM detects that the acceleration mode is active without the activation of the Accel. switch.
Injector Disable: The PCM/ECM detects that the engine is overspeed and that the fuel shutoff has been activated.
Low Speed: The PCM/ECM detects that the vehicle speed is less than 37 km/h (23 mph) while the cruise control system was enabled.
Low Voltage: The PCM/ECM detects that the ignition voltage is below 9 volts.
Manual/Neutral: The PCM/ECM detects that transmission is in Neutral, Reverse or Park.
Memory Corrupt: An internal PCM/ECM memory fault is detected.
MPH Limit: The PCM/ECM detects a that the vehicle is overspeed and that the fuel shutoff has been activated.
No History: This parameter is displayed when a new PCM/ECM has been installed.
None: This parameter is displayed when a new PCM/ECM has been installed.
Off: The PCM/ECM detects that the cruise On/Off switch was turned to Off when the cruise control system was enabled.
Over Set Speed: This parameter is displayed when the current vehicle speed is greater than the set vehicle speed by more than a calibrated amount.
Over Speed: This parameter is displayed when the current vehicle speed is greater than the set vehicle speed by more than a calibrated amount.
Over Speed Tap: This parameter is displayed when the Set/Coast switch is briefly applied while the current vehicle speed is greater than the set vehicle
speed by more than a calibrated amount.
Pedal Initialize: The PCM/ECM detects that a stop lamp pedal activation had not occurred before the cruise control system was requested.
PCM Error: The PCM/ECM detects that a cruise control software execution error is present.
PCM Inhibit: The PCM/ECM detects a RAM corruption associated to the cruise control system.
Pedal Cruise: The PCM/ECM detects that the accelerator pedal overrides the set vehicle speed for approximately 60 seconds.
Serial Data: A fault in the serial data circuit from the cruise control switch to the platform module is detected.
S/C On, S/C Off: When the PCM/ECM detects that the cruise set/coast signal is active and the throttle blade fully closes the cruise control system will
disengage until the PCM/ECM detects that the set/coast signal is inactive. The cruise control system will then engage and set with the new vehicle speed.
S/C On - Speed High: This parameter is displayed when the Set/Coast switch is briefly applied while the current vehicle speed is greater than the set
vehicle speed by more than a calibrated amount.
Stop Lamp Switch: The PCM/ECM detects that the stop lamps have been activated.
TAC Inhibit: The PCM/ECM detects a fault within the TAC system.
Traction: The PCM/ECM detects that the traction control system had been activated. It is also possible that a tire with low air pressure can also set this
disengagement reason.
Traction Loss: The PCM/ECM detects that the traction control system had been activated. It is also possible that a tire with low air pressure can also
set this disengagement reason.
