Warning Light Circuit: Description

• The key warning indicator light, which is built into the combination meter, comes on or blinks as a warning to the driver.
• The certification ECU sends key warning indicator light on / blink request signals to the combination meter via BEAN.

HINT:

If the key warning indicator light does not come on or blink properly, there may be a problem in the power source of the multiplex communication system and combination meter or in the certification ECU.
