C1782

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 Data link Left and Right Outputs. The EBTCM uses this information to provide improved rough-road braking performance.

CONDITIONS FOR SETTING THE DTC
The Diagnostic Trouble Code (DTC) is set when the CVRSS control module measures a feedback voltage greater than a preset threshold during an ICCS2 Data link Left Output ON state. The DTC turns HISTORY when the CVRSS control module no longer senses a high feedback voltage during five (5) consecutive ICCS2 Data link Left Output ON states.

ACTION TAKEN WHEN THE DTC SETS
^ Both of the ICCS2 Data link Outputs are set to default output states.
^ The SERVICE RIDE CONTROL message will be displayed.

CONDITIONS FOR CLEARING THE MIL/DTC
^ Use the scan tool
^ Use the On-Board diagnostic CLEAR RSS CODES feature.

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
1. This step checks for a short circuit to battery condition in circuit 960.

IMPORTANT:
^ Do not backprobe the sensors, actuators, or any sealed connectors.
^ When all the diagnostics and repairs are complete, clear the DTCs and verify the operation.
