Pressure Deviation Alert
The Pressure Deviation Alert is initiated when the measured tire pressure deviates from the required pressure by more than the preset level. The gage light will change colors and alert indicator flashes on and off. The audible alarm sounds once and the digital readout displays the amount of deviation from required pressure. Press any button to acknowledge the alert and stop the flashing, the gage light remains on and the system returns to normal mode.
Example:
Pressure Deviation Alert Level = ±5 PSI (0.34 Bar)
Required Pressure = 35 PSI (2.40 Bar)
Actual Pressure in a wheel drops to 30 PSI (2 Bar)
Pressure Deviation reading as shown will be -5 PSI (0.34 Bar). You should stop and check your tires as soon as possible. The Pressure Deviation Alert is cancelled when the tires are properly re-inflated to correct levels. See Capacities and Specifications for Tire Pressure Monitoring System Setting Chart.
Low Pressure Warning
A Low Pressure Warning is initiated when the pressure drops below the programmed level. The gage light, low-pressure warning indicator and the audible alarm turn on and off continuously. Press any button to acknowledge and stop the flashing. The gage light remains on and the display reverts to a normal mode. The Low Pressure Alert is cancelled when the tires are properly re-inflated to correct levels. See Capacities and Specifications for Tire Pressure Monitoring System Setting Chart.
High Pressure Warning
The High Temperature Alert is initiated when the air temperature within a tire exceeds the programmed level. The temperature alert indicator and audible alarm turn on and off continuously. Press any button to acknowledge the alert and stop the flashing. The gage light remains on and the display reverts to a normal mode. The High Pressure Alert is cancelled when the tires are properly re-inflated to correct levels. See Capacities and Specifications for Tire Pressure Monitoring System Setting Chart.
Error Code
An E1 error code may be displayed if the vehicle is not in motion for 15 minutes or longer with the key in the ON position. If after 5 minutes of driving 6 mph (10 kph) or greater the code is still present, contact your GM Goodwrench® dealer.
