Coolant Level Indicator Lamp: Customer Interest
Instruments - Low Coolant Warning On Driver Info Center

Number

85-8-18

Date

10/85

Subject:

"LOW COOLANT" WARNING ON DRIVER INFORMATION CENTER

1985 GRAND AM

CONDITION:

Driver  Information  Center  flashes  a  "low  coolant"  warning. However, a visual check of the coolant level shows that it is not low.

CAUSE:

Electromagnetic interference (EMI) causes the DIC to interpret a stray signal as a low coolant.

CORRECTION:

Replace DIC module P.N. 25076572 with module 25072474.  All VIN's prior to FC736995 may be affected.  (Any DIC's that were replaced in service
and do not indicate a "low coolant" warning need not be changed.)
