QUESTION: Fuel Data window displays: 88.8, E48, E52, 8.8.8, 7.0
AnswerOK, Lets see if we can CLEAR (erase) the E48 and E52 codes.
1. Go back into diagnostics OFF & WARMER and when you see .7.0
2. Simultaneously push and hold the OFF and HI (^) buttons on the climate control panel until you see E.0.0 and release the buttons.
3. drive the car and see if the codes come back. The 88.8 and .70 are NOT codes thay are the beginning and ending of the diagnostics.
