When switching between an AFM and MAP calibration the service maintenance reminder will sometimes trigger. This illuminates the wrench light on the dash and the dash displays 'service A' or 'service B' along with a negative number of miles.
To clear the maintenance minder light:
| • | Switch the ignition on, but do not start the engine. |
| • | Hold down the 'SEL/RESET' button for 10 seconds, until the display starts to flash. |
| • | Release the 'SEL/RESET' button, and then hold it down for an additional 6 seconds. The display will clear. |
