Road Sensing Suspension (RSS)

CIRCUIT DESCRIPTION
The RSS module monitors the steering sensor data for a sensor out-of-range condition.

CODE RS0080 WILL SET WHEN
The RSS module senses the steering sensor signal below 0.6 volts or above 4.75 volts for more than 10 seconds while at a vehicle speed of 50 MPH.

ACTION TAKEN
Sets a code RS0080, turns on the "SERVICE RIDE CONTROL" message, and sets steering wheel angle to 0 degrees.

CODE RS0080 WILL GO "HISTORY" WHEN
The RSS module no longer senses an out-of-range condition on the steering sensor signal.

DIAGNOSTIC AIDS
History codes are used to help diagnose intermittent fault conditions and do not necessarily indicate a faulty RSS module. The RSS module itself is a reliable component and is not likely the cause of the malfunction. Most system complaints are linked to faulty wiring and connectors and, occasionally, components.

Performing a thorough inspection of all related wiring and connectors pertaining to the history code stored will reduce diagnostic time and prevent unnecessary part replacement. If the problem is intermittent, try performing the tests shown while "wiggling" wiring and connectors. This can often cause the malfunction to appear. Check for poor connections at both the RSS module and the related components. These could cause an open, short, or an intermittent malfunction. Refer to Intermittents And Poor Connections. Diagnostic Aids

NOTES ON FAULT TREE
1. Refer to Intermittents And Poor Connections. Diagnostic Aids
2. After replacing the position sensor always perform the Electronic Leveling Control (ECL) Trim Height Adjustment. Suspension Control ( Automatic - Electronic )
3. Refer to Clearing Diagnostic Trouble Codes. Clearing Diagnostic Trouble Codes

IMPORTANT
^ Do not backprobe sensors, dampers, electronic leveling control (ECL) connectors, or SSS connectors.
^ When all diagnosis and repairs are complete, clear codes and verify operation.
