WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
- Test for a fully engaged hybrid battery pack high voltage S15 manual service disconnect whenever an open or intermittent high voltage interlock circuit condition is observed. The hybrid battery pack high voltage manual disconnect lever must be fully inserted in the base and the locking pins engaged before rotating the cam lever down. When properly installed the high voltage manual disconnect lever should be flush with the base.
- With all monitored high voltage components engaged and the High Voltage Interlock Circuit is Energized, observe the scan tool hybrid/EV powertrain control module 2 High Voltage Interlock Circuit Status parameter for a PASS status. To help identify intermittent conditions, manipulate the monitored components and inline connectors. An open interlock circuit will display a FAIL status.
