Road Sensing Suspension (RSS)

CIRCUIT DESCRIPTION
The RSS module monitors the position sensor supply voltage for a fault condition that prevents correct supply regulation.

CODE RS0066 WILL SET WHEN
A code RS0062 is present and the RSS module has detected that the position sensor supply line is less than 7.0 or greater than 9.0 volts.

ACTION TAKEN Sets a code RS0066 and RS0062 and turns on the "SERVICE RIDE CONTROL" message.

CODE RS0066 WILL GO "HISTORY" WHEN
The RSS module no longer senses the an over-current condition on the position sensor supply circuit.

DIAGNOSTIC AIDS
A position sensor signal fault 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. 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.
