If your 2007 Chevy Tahoe Hybrid is unable to crank, it is likely due to the hybrid motor lacking sufficient power to start the engine, as opposed to a traditional starter motor and 12V battery. In this SUV, the hybrid electric motor serves the dual purpose of driving the wheels and initiating the engine's start-up. In the event of a vehicle shutdown, you can utilize an OBD II scan tool to activate jump mode, enabling the use of regular jumper cables. Jump assist mode permits the hybrid motor to access the 12V battery located under the hood in an attempt to start the car, bypassing the standard 300-volt system. If this method proves unsuccessful, it may be necessary to have the vehicle towed to a dealership for hybrid battery replacement.
Why not sick?
Where do I need to go on the scanner to switch it to jump mode?
Where can I find an OBD2 scanner?
The reason why the 2008 Chevy Tahoe won't start could be because the battery is dead or there is a problem with a wire in the hybrid system.
