Under most conditions, the Insight engine is started by the IMA motor, which instantly spins the engine to 1000 rpm.

The Insight also has a conventional 12v auxiliary starter motor that is used in the following situations:

• The state of charge of the Battery Module is too low.
• The ambient temperature is too high or too low.
• There is a failure of the IMA system.

Because the Insight won't enter idle stop mode in any of the above situations, all engine starts other than the initial start will always be done using the IMA motor.

To test the 12v auxiliary starting system, first disable the IMA starting system by removing fuse #2 from the under-dash fusebox.
