Notes on Intermittents

INTERMITTENTS AND POOR CONNECTIONS
Intermittent failures in electronic systems may be very difficult to detect and accurately diagnose. The Continuously Variable Road Sensing Suspension (CVRSS) control module tests for different vehicle conditions; for this reason, it is often necessary to perform a test drive to repeat the failure and allow a code to set. If the system malfunction is not repeated during the test drive, a good description of the complaint may be very useful in locating an intermittent fault condition. Most intermittent problems are caused by faulty electrical connections or wiring. When an intermittent condition is suspected, check suspected circuits for:
^ Poor mating of connector halves or terminals not fully seated in connector body (backed out).
^ Improperly formed or damaged terminals.
^ Dirt or corrosion on the terminals.
^ Damaged connector body
HISTORY codes are used to help diagnose intermittent fault conditions and do not necessarily indicate a faulty CVRSS control module. Most system complaints are linked to faulty wiring and connectors, and occasionally components. Always perform a thorough inspection of all related wiring and connectors pertaining to the HISTORY code stored. The following conditions may result in an intermittent operation of the SERVICE RIDE CONTROL message with no Code (s) stored:
^ Any condition which results in interruption of power to the CVRSS control module.
^ Battery or ignition voltage which is out of range (below 10 Volts or above 16 bolts)
^ Loose or damaged grounds
