Maintenance Reminder Flag - Reseting Procedure
Bulletin 84-6E-9Date March '84
Ref. No. 84-068-6E
SUBJECT: MAINTENANCE REMINDER FLAG RESET
MODELS AFFECTED: VEHICLES EQUIPPED WITH SPEEDOMETER EMISSION SERVICE FLAG
Beginning in 1978, Buick began using an emission reminder flag incorporated within the speedometer on certain models, to alert the customer that an emission device on their vehicle was due for service or replacement. Depending on the speedometer design used for different models, one of two resetting procedures must be used. The emission flag resetting procedures are detailed in the following illustrations.
To avoid early deployment of the flag (and to avoid causing a "comeback") it is important to feel 3 clicks or detents of the flag wheel and to insure that the alignment mark is in the center of the window after resetting is complete, per #3 in both illustrations.
FIGURE 1 - SPEEDOMETERS WITH REMOVABLE LENS:
Procedure for Speedometers With Removable Lens (See Figure 1)
1. Detent on flag outer rim.
2. A. Remove instrument cluster bezel.
B. Remove instrument cluster lens.
C. Using pointed tool turn flag wheel downward. Insert tool at an angle to engage detents.
3. Alignment mark must be in center of window when reset.
FIGURE 2 - 1980 BUICK B-C SPEEDOMETERSPEEDOMETERS (NON REMOVABLE LENS):
Procedure for 1980 Buick B-C Speedometers (Non Removable Lens) (See Figure 2)
1. Remove instrument cluster bezel.
2. Pull cable until flag wheel hits a built-in stop. When properly reset, a black location mark on the edge of the flag must be visible thru the odometer window.
3. Alignment mark must be in center of window when reset.
