Problem Phenomenon
DESCRIPTION
1989 323, 626, 929 and MPV (3.0L) models produced between November 1988 and January 1989 may exhibit the following problem in temperatures of
less than 0~C.
The problem is that the engine starts while the I.G. key is turned to the "START" position, but immediately stalls when the key is returned to the "ON"
position. This occurs only when the temperature of the Emission Control Unit (E.C.U.) is approximately 0~C or less. However, the engine operates
normally when the temperature is higher than 0~C.
REPAIR PROCEDURE
1.
Verify whether the engine stalls under the above condition.
2.
Replace the E.C.U. if the problem is observed.
