The inadvertent power relay is controlled by the body control module (PZM). The PZM grounds the inadvertent power relay through connector C2 terminal C3.
The inadvertent power relay is commanded ON or OFF and the PZM feed back does not match that of the commanded state for at least 2 seconds.
The PZM continues to command the requested state of the relay until the state is achieved or no longer necessary.
• | The PZM feedback matches that of the commanded state for at least 2 seconds. |
• | A history DTC clears after 50 consecutive ignition cycles if the condition is no longer present. |
