Diagnostic Aids

Press and release the VSES mode switch several times while observing the message center in order to verify that the VSES full stability/limited status changes each time the switch is pressed and that DTC C0283 does not set. Using the scan tool in order to observe the Mode Switch Pressed or Released status may also be helpful in diagnosing an intermittent fault within the switch.

Thoroughly inspect connections or circuitry that may cause an intermittent malfunction. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS .
