Electronic Suspension Control Scan Tool Output Controls
| Output Control | Description |
|---|---|
| LF Damper Actuator Command | Commands the left front shock solenoid ON and OFF. |
| LR Damper Actuator Command | Commands the left rear shock solenoid ON and OFF. |
| RF Damper Actuator Command | Commands the right front shock solenoid ON and OFF. |
| RR Damper Actuator Command | Commands the right rear shock solenoid ON and OFF. |
| Reset Diagnostic Counter | Commands the module to reset the internal ignition cycle counter. This enables the module to set DTCs immediately by bypassing the requirement to see the fault condition for 3 consecutive ignition cycles before a DTC is set. Once the ignition is cycled the ignition cycle count is re-enabled. |
