Component Resistance

WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

Connect DMM between specified terminals at component or at transaxle in-line 20-pin connector to transaxle. Measure individual component resistance at specified temperature. See Figure and Figure . See COMPONENT RESISTANCE . If resistance is not as specified, replace appropriate component. See Fig 2 .
