The RTD scan tool data display values and definition information that can assist in diagnosing RTD 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

Compressor Signal (If Equipped) -- ON/OFF: This data indicates when the compressor relay is activated.

Controller Battery Voltage--Range 10.0-16.0 Volts: This data refers to the battery system voltage as measured by the suspension control module.

EVO Actual Current (If Equipped) -- ma: The scan tool displays the current that the ESC module is actually commanding to the EVO solenoid.

EVO Desired Current (If Equipped) -- ma: The scan tool displays the current that the ESC module is trying to command to the EVO solenoid.

EVO Drive PWM (If Equipped) -- Percent: The scan tool displays the percentage of available voltage for the EVO solenoid.

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.

Left Front Position Sensor--Range 0.5-4.5 Volts: This data refers to the vehicle height measured in volts.

Left Rear Damper Actuator--ON/OFF: This data refers to the state of the suspension damper solenoid contained within the shock absorber.

Left Rear Position Sensor--Range 0.5-4.5 Volts: This data refers to the vehicle height measured in volts.

Lift/Dive Status -- Active/Inactive: This data indicates when a change in pitch status is detected

Rear Leveling Air Pressure (If Equipped) -- psi/kpa: This data indicates the system pressure in psi.

Rear Leveling Air Pressure (If Equipped) -- Volts: This data indicates the system pressure in volts.

Right Front Damper Actuator--ON/OFF: This data refers to the state of the suspension damper solenoid contained within the shock absorber.

Right Front Position Sensor--Range 0.5-4.5 Volts: This data refers to the vehicle height measured in volts.

Right Rear Damper Actuator--ON/OFF: This data refers to the state of the suspension damper solenoid contained within the shock absorber.

Right Rear Position Sensor--Range 0.5-4.5 Volts: This data refers to the vehicle height measured in volts.

Sensor Supply Voltage -- Volts: This data indicates the voltage being supplied to the sensors from the ESC module.

Steering Wheel Position Signal 1 -- Volts: The scan tool displays the output voltage of the signal 1 circuit of the Steering Wheel Position Sensor.

Steering Wheel Position Signal 2 -- Volts: The scan tool displays the output voltage of the signal 2 circuit of the Steering Wheel Position Sensor.

Steering Wheel Rate -- RPM: The scan tool displays the speed at which the steering wheel is turning.

Vehicle Speed -- Range -- -193 km/h (0-120  mph): This is the ESC module measurement of the vehicle's speed from a discrete output from the powertrain control module (PCM).

Vehicle Speed (ZK3) -- Range--0 -193 km/h (0-120  mph): This is the ESC module measurement of the vehicle's speed from a discrete output from the powertrain control module (PCM). This is used for earlier version of ESC module used.
