Hybrid Electric Indicators
The hybrid electric warning indicators alert the driver that a hybrid electric system concern is detected. There are 3 indicators dedicated to the hybrid electric system:
- over-temperature indicator
- powertrain malfunction indicator (wrench)
- hazard indicator
Over-Temperature Indicator - The PCM monitors the engine, the motor electronics coolant temperature (MECT), and the electronically controlled continuously variable transaxle (CVT) for an over-temperature condition. If either of the temperatures exceed their threshold value, the fail-safe cooling status changes status to ON, and the PCM broadcasts an over-temperature indicator on controller area network (CAN) message to the instrument cluster. The instrument cluster then illuminates the indicator light. The over-temperature indicator is extinguished when the temperature returns below the threshold value.
Powertrain Malfunction Indicator (Wrench) - The powertrain malfunction indicator (wrench) is illuminated whenever a concern within the hybrid electric system is detected and a repair is needed. When the concern is present, the control module that detected the concern stores the diagnostic trouble code (DTC) and broadcasts a caution on CAN message to the instrument cluster. Upon receiving the CAN message, the instrument cluster turns the indicator on.
Two actions can extinguish the powertrain malfunction indicator (wrench):
- the module requesting the indicator ON is reset.
- the concern is not present anymore and the key is cycled.
If the powertrain malfunction indicator (wrench) flashes at the once per second rate, it indicates that the vehicle is in the engine running diagnostic mode. Refer toDIAGNOSTIC MODES for engine running diagnostic mode. The powertrain malfunction indicator (wrench) illuminates for 3 seconds during instrument cluster prove-out when the key is cycled from the OFF to the ON position.

Hazard Indicator (Red Triangle) - The hazard indicator is illuminated whenever a severe concern within the hybrid electric system is detected and continued use of the vehicle is likely to cause damage to the system or to the vehicle. When the concern is present, the control module detects, sets the DTC and broadcasts a hazard on CAN message to the instrument cluster. Upon receiving the CAN message, the instrument cluster turns the indicator on.
Two actions can extinguish the hazard indicator:
- the module requesting the indicator on is reset.
- the concern is not present anymore and the key is cycled.
If the hazard indicator flashes at the once per second rate, it indicates that the vehicle is in the engine cranking diagnostic mode. Refer toDIAGNOSTIC MODES for engine cranking diagnostic mode. The hazard indicator illuminates for 3 seconds during the instrument prove-out when the key is cycled from the OFF to the ON position.
