INTERMITTENT ECM CONNECTION - MAY BE WEAK TERMINAL GRIP

Model(s): 1988 Pontiac Models

Bulletin No.: Pontiac 88-8-13

Date: 05/31/1988

CONDITION

A condition may exist in which the female terminals in the connector to the ECM do not make a solid connection to the male pins in the ECM (see illustration). This can result in an intermittent condition, in any circuit operated by the ECM. The Service Manuals direct a check of connections any time an intermittent condition is found, and this may be the cause of some of these conditions.

CORRECTION

Visually inspect the terminal using a flashlight, or use a .95mm pin gage.

The gage should not pass freely through the female terminal. Do not probe the terminal with anything other than the pin gage, as probing could damage the terminal. If the female terminal does not grip properly, replace the terminal with P/N 12020757. General directions on wiring repair are shown in Section 8A of the Service Manual.

Use existing Labor Operations.
