C1760

CIRCUIT DESCRIPTION
The CVRSS position sensor provides an analog voltage (0 - 5 volts) to the CVRSS module which represents the position between the body and the wheel. The CVRSS module provides the sensor with 5.0 volt supply. The sensor is also grounded through the CVRSS module.

CONDITIONS FOR SETTING THE DTC
^ The DTC is set when the CVRSS module measures the position sensor signal voltage below 0.35 volts or above 4.75 volts for more than 1.0 second.
^ The DTC turns HISTORY when the CVRSS module senses voltage in the normal range (0.35 - 4.75 volts) for more than 1.0 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.

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 back probe 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.
29. This step checks for a short circuit condition in the sensor feed circuit.
31. This step checks for a short to battery voltage condition in the sensor feed circuit.
