Circuit Description

WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) supplies a ground path for the crank relay when start enable has been requested. The PCM monitors this circuit for conditions that are incorrect for the commanded state. If the PCM detects an improper circuit condition, starter relay DTC P0615 will set.
