If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the
situation. Check the following and perform the appropriate proce-
dure:
■ The hybrid system will not start, even though the correct
starting procedure is being followed. ( P. 135)
One of the following may be the cause of the problem.
● The electronic key may not be functioning properly. ( P. 433)
● There may be a malfunction in the immobilizer system.
( P. 8 8 )
● There may be a malfunction in the steering lock system.
● The hybrid system may be malfun ctioning due to an electrical
problem such as an open circuit or a blown fuse. However,
depending on the type of malf unction, an interim measure is
available to start the hybrid system. ( P. 430)
■ The interior lights and headlights are dim, or the horn does
not sound or sounds at a low volume.
One of the following may be the cause of the problem.
●The 12-volt battery may be discharged. ( P. 436)
● The 12-volt battery terminal c onnections may be loose or cor-
roded.
