Hummer H3. Manual — part 931

The PCM/ECM detects that the clutch pedal switch has been activated.

Cruise Off

The PCM/ECM detects that the cruise On/Off switch was turned to OFF when the cruise
control system was enabled.

Coast Low Speed

The PCM/ECM detects that the Set/Coast switch is activated until the vehicle speed is
below 37 km/h (23 mph).

Coast Disengage

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.

Decel Rate

The PCM/ECM detects that the vehicle deceleration is greater than the calibrated cruise
control threshold.

DTC Set

The PCM/ECM detects that a DTC has been set which affects the cruise control operation.

Engine Run Time

The PCM/ECM detects that the cruise control system has been requested and the engine run
time counter is not active.

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 throttle actuator control (TAC) system.

First Gear

2007 Hummer H3

2007 ACCESSORIES & EQUIPMENT Cruise Control - H3

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

2007 Hummer H3

2007 ACCESSORIES & EQUIPMENT Cruise Control - H3

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

2007 Hummer H3

2007 ACCESSORIES & EQUIPMENT Cruise Control - H3

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, CC 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.
