C1782

CIRCUIT DESCRIPTION
The CVRSS 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.

CONDITIONS FOR SETTING THE DTC
The DTC is set when the CVRSS module measures a feedback voltage greater than a preset threshold during an ICCS2 Datalink Left Output ON state.

The DTC turns HISTORY when the CVRSS module no longer senses a high feedback voltage during five (5) consecutive ICCS2 Datalink Left Output ON states.

ACTION TAKEN WHEN THEN DTC SETS
^ Both of the ICCS2 Datalink 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

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

The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks for a short circuit to battery condition in circuit 790.
