  1. Test drive vehicle. If odometer accumulates 10 miles and then loses 10 miles, go to step 3). If odometer accumulates zero mileage, go to next step.
  2. Verify that speedometer works properly. If okay, replace EIM. If not, perform SPEEDOMETER READS "0" WITH VEHICLE IN MOTION test.
  3. Replace non-volatile memory module and recheck odometer operation. If odometer now accumulates mileage, system is okay. If not, replace EIM.
