The service reminder indicator (SRI) informs the driver that it is time for the car to be serviced. The lamp remains lit for 120 seconds when the ignition is switched on.

-Ignition position I
-Press and hold in the reset button for the trip odometer
-Ignition position II
-The service reminder indicator (SRI) starts flashing when the reset button for the trip odometer has been pressed for 10 seconds

any other sugestion?

 

I have a similar probelm with my 1999 S-80 2.9 136000miles. The "Engine System Service Required" indicator came on. The mechanic said no service codes were on. I went throught reset sequence and it went off for a while but then came back on.

What does this messge mean and am I going the right directionto have it turned off or reset?

 

Very simple folks..

Position I...press and hold down trip button..change to Position II..wait for the lights to blink 3 times..let up on trip button..turn off the ignition.

Start the car..it should be gone...
