Malfunction Indicator Lamp: Service and Repair
SERVICE VEHICLE SOON INDICATOR
The "SERVICE VEHICLE SOON" light will come on if there are certain non-emission related vehicle problems.
These problems may not be obvious and may affect vehicle performance or durability. The light will come on briefly when the ignition is turned on to
show that it is working properly.
This light does NOT come on at certain mileage intervals.
There is probably a PCM or a BCM Code set that will aid you in diagnosis.
RESET PROCEDURE
The only way to get the light to go off is to clear the PCM or BCM code(s).
This light can NOT be reset or shut off any other way.
PCM/BCM codes should be read & repaired before clearing them.
