B2818

DTC B2818





Circuit Description
The Instrument Panel Cluster (IPC) monitors the Tire Press Reset switch signal circuit, w/systems monitor, or Driver Information Center (DIC) Reset switch signal circuit, w/DIC. If the IPC detects a ground on either switch signal circuit for more than a predetermined amount of time, a malfunction is detected.

Conditions for Running the DTC
^ The ignition is ON.
^ Ignition voltage is 10.5 - 14.7

Conditions for Setting the DTC
The IPC detects a ground on the Tire Press Reset switch signal circuit, or the DIC Reset switch signal circuit, for mole than 15 continuous seconds.

Action Taken When the DTC Sets
^ A DTC B2818 is stored in memory.
^ The IPC ignores the Reset switch signal circuit input.

Conditions for Clearing the MIL/DTC
^ A current DTC will clear on the next consecutive malfunction free ignition cycle.
^ A history DTC will clear after 100 consecutive malfunction free ignition cycles.
^ Using a scan tool

Diagnostic Aids
The IPC disables the switch input when a malfunction is detected making the switch status unknown when viewing the Reset switch parameter with a scan tool.
If an intermittent malfunction is suspected, cycle the ignition after repositioning wires and connectors to verify correct Reset switch status.
