Road Sensing Suspension (RSS)

CIRCUIT DESCRIPTION
The RSS module monitors the position sensor data for an "out-of-range" condition. The signal is out-of-range if it is under voltage (0.35v) or over voltage (4.75v).

CODE RS0060 WILL SET WHEN
The RSS module senses the position sensor signal is out of the normal range of 0.35 to 4.75 volts for 1 second.

ACTION TAKEN
The RSS module will display the "SERVICE RIDE CONTROL" message and switch all four of the damper solenoid valves to the firm position.

CODE RS0060 WILL GO "HISTORY" WHEN
The RSS module senses the correct position sensor input voltage.

NOTES ON FAULT TREE
1. Refer to Intermittents And Poor Connections. Diagnostic Aids
2. Refer to Clearing Diagnostic Trouble Codes. Clearing Diagnostic Trouble Codes

DIAGNOSTIC AIDS
The position sensor code may be set due to the corresponding position sensor overcurrent code being set. If this is the case, the overcurrent code must be diagnosed and repaired first.

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.

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.
