Number 106
Corp. Ref. No. 918306
Date July, 1989
SUBJECT: TRIP ODOMETER DISPLAYS ALL ZEROS AT ALL TIMES


MODELS AFFECTED: 1986-1989 ELDORADOS AND SEVILLES


Some 1986-1989 Eldorados and Sevilles may exhibit a condition of the trip odometer displaying all zeros, while the season odometer continues to accumulate mileage. This may be due to the trip reset button continuously resetting.

When working on a vehicle with this condition, replace the trip reset button with a known good button from another vehicle. If the trip odometer begins to accumulate mileage, replace the trip reset button, P/N 25079404. Parts are currently available from GMSPO.

Refer to Section 8C of the Eldorado/Seville Service Information Manual for trip reset button replacement procedure.

If the trip odometer continues to display all zeros with a known good trip reset button installed, exchange the EPC. Refer to DSIB 89-I-24 for electronic instrumentation repair and exchange information.
