CIRCUIT DESCRIPTION
The CVRSS position sensor provides an analog voltage (0 to 5 volts) to the CVRSS control module which represents the position between the body and the wheel. The CVRSS control module provides the sensor with an 8 volt supply. The sensor is also grounded through the CVRSS control module.

CONDITIONS FOR SETTING THE DTC
The DTC is set when the CVRSS control module measures the position sensor signal voltage below 0.35 volts or above 4.75 volts for more than I second.

The DTC turns HISTORY when the CVRSS control module senses voltage in the normal range (0.35 - 4.75 volts) for more than 1 second.

ACTION TAKEN WHEN THE DTC SETS
^ The CVRSS will enter the Speed Dependent damping mode.
^ Both ICCS2 Datalink Outputs will be set to the default output states.
^ The SERVICE RIDE CONTROL message will be displayed.
^ Rear leveling will ignore the faulted position sensor input.
^ The ALC will be disabled if both rear position sensors are faulted.

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

DIAGNOSTIC AIDS
This fault condition may be set due to the CVRSS position sensor supply over-current fault. If this is the case, the position sensor supply over-current fault (C1768) must be diagnosed first.

TEST DESCRIPTION

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.

The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks to see if the sensor supply line is faulted.
3. This step checks for mechanical problems.
4. This step checks for a low voltage fault condition.
5. This step checks for an open circuit condition in the supply line or signal line.
13. This step checks for a short circuit condition between the sensor ground and the signal line.
15. This step checks for a short circuit condition between the sensor signal and chassis ground.
17. This step checks for a high voltage fault condition.
18. This step checks for a short to battery voltage condition on the sensor signal line.
19. This step checks for a short circuit condition between the sensor signal line and the supply line.
21. This step checks for an open circuit condition in the controller to ground path.
23. This step checks for an open circuit condition in the controller to ground path.
