Scan Tool Data Definitions
Compressor Signal: Indicates when the compressor relay is activated.
Controller Battery Volts: Range 10.0 V-16.0 V This data refers to the battery system voltage as measured by the suspension control module.
Exhaust Signal: Indicates when the exhaust solenoid is commanded on or off.
Left Rear Position Sensor: Range 0.5 V-4.85 V This data refers to vehicle height measured in volts.
Rear Leveling Air Press: Indicates the system pressure in psi.
Rear Leveling Air Press: Indicates the system pressure in volts.
Right Rear Position Sensor: Range 0.5 V-4.85 V This data refers to vehicle height measured in volts.
Sensor Supply Voltage: Indicates the voltage being supplied to the sensors from the suspension control module.
Vehicle Speed: The speed of the vehicle.
Scan Tool Data Definitions - ESC
Scan Tool Data Definitions
The electronic suspension control (ESC) scan tool data display values and definition information that can assist in diagnosing ESC related problems,
especially when no diagnostic trouble codes (DTC) are stored in memory. A vehicle's scan tool data can be compared with the data display values
from a known good vehicle in the scan tool data display table. When data from the vehicle differs from the typical data display value, the data
definition information will help in understanding the nature of the difference and the source of the problem. This list is in alphanumeric order.
Data Definitions
Battery Voltage Signal-Range 10.-16.0 Volts: This data refers to the battery system voltage as measured by the suspension control module.
Compressor Signal, if equipped-ON/OFF: This data indicates when the compressor relay is activated.
Digital SWPS Phase A-High/Low: This data indicates the state of phase A in the steering wheel position sensor.
Digital SWPS Phase B-High/Low: This data indicates the state of phase B in the steering wheel position sensor.
Exhaust Signal, if equipped-ON/OFF: This data indicates when the exhaust solenoid is commanded On or Off.
Left Front Damper Actuator-ON/OFF: This data refers to the state of the suspension damper solenoid contained within the shock absorber.
