Pinpoint Tests QB: Keep Alive Power: Introduction
WARNING:
To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.
This pinpoint test is intended to diagnose the following:
- battery cables loose or intermittent connections
- harness circuit: KAPWR
- engine cooling system concerns
- PCM (12A650)
