INSTRUMENT CLUSTER WARNING LAMPS

Malfunction Indicator Lamp (MIL)

•

The yellow MIL indicates a vehicle malfunction that requires

service.

•

The MIL will illuminate during these conditions:

– a concern exists where long-term damage may result

– when a less serious concern occurs twice within five key cycles

•

The IAA monitors the other “smart” modules and uses the MIL to

indicate a concern.

Low Fuel Warning Lamp

Low Fuel Warning Lamp

•

The Low Fuel Warning Lamp alerts the driver when the state of

charge is low.

•

This lamp illuminates when the traction battery state of charge

reaches 10%.

– Limited operating strategy is in effect when the lamp is

illuminated to conserve remaining power.

•

The Low Fuel Warning Lamp will flash when the battery state of

charge reaches 0% (the vehicle has very limited range at this point).

– Speed is limited to 10 km/h (6 mph).

POWER LIMIT Warning Lamp

POWER LIMIT Warning Lamp

•

The IAA monitors input from the TIM through the J1850 (SCP)

network and uses the POWER LIMIT Warning Lamp to indicate

the vehicle’s performance is limited to conserve remaining battery

power (lamp illuminated).

•

As the traction battery nears complete discharge, the lamp begins to

flash to indicate performance is further limited to allow for safe

parking of the vehicle before the battery is completely drained.
