• The electric shift selector sends shift position information to VCM.

• BCM transmits a door switch signal to VCM.

• VCM judges the vehicle condition according to shift position information and a door switch signal. VCM

transmits a shift P range request display signal to the combination meter if the driver’s door is opened with

the shift position not in P position.

WARNING/INDICATOR OPERATING CONDITION

When all of the following conditions are satisfied:

• Shift position: Except P range

• Front door (driver side): Open

SYSTEM DIAGRAM

SIGNAL PATH

• VCM monitors 12V battery voltage, and if the voltage drops, then VCM transmits a DC/DC converter warning

request signal to the combination meter to operate a DC/DC converter warning chime.

• When VCM receives a P position signal from the electric shift selector, the operation of DC/DC converter

warning chime is cancelled.

WARNING OPERATING CONDITION

When all of the following conditions are satisfied:

• Shift position: Except P range
• 12V battery voltage stays low (approximately 10 – 12 V or less)

*

 for a few consecutive seconds.

*: Threshold voltage depends on vehicle speeds.

NOTE:

When 12V battery voltage drops sharply while in READY state, the READY state is also cancelled.

WARNING CANCEL CONDITION

When any of the following conditions are satisfied:

• Shift position: P range

• The 12V battery voltage returns to approximately 12.5 V or more.
