C1784

CIRCUIT DESCRIPTION
The Continuously Variable Road Sensing Suspension (CVRSS) control module estimates the road surface and communicates that information to the Electronic Brake and Traction Control Module (EBTCM) using the ICCS2 Datalink Left and Right Outputs. The EBTCM uses this information to provide improved rough-road braking performance.

CONDITION FOR SETTING THE CODE "CURRENT"
The CVRSS control module measures a feedback voltage greater than a preset threshold during an ICCS2 Datalink Right Output ON state.

ACTIONS TAKEN WHEN CODE SETS "CURRENT"
^ Both ICCS2 Datalink Outputs are set to default output states.
^ The "SERVICE RIDE CONTROL" message is displayed.

CONDITION FOR CODE TURNING "HISTORY"
The CVRSS control module no longer senses a high feedback voltage during five (5) consecutive ICCS2 Datalink Right Output ON states.

HOW TO CLEAR THE CODE
^ Use the scan tool.
^ Use the On-Board diagnostic "CLEAR RSS CODES" feature.
