Reduced Engine Power

The reduced power telltale is turned On by the cluster when it receives a command from the BCM. The ECM (L81) engine sends a message to the BCM over the CAN serial data link.

The reduced power telltale is illuminated when the ECM is limiting engine torque in a low traction situation. This telltale is used only for the V6 (L81) engine application.

The reduced power telltale is turned On by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.
