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 ignition 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 to DIAGNOSTIC MODES for engine running diagnostic mode. The powertrain malfunction indicator (wrench) illuminates for 3 seconds during instrument cluster prove-out when the ignition is cycled from the OFF to the ON position.
